The Jones and Shipman 524 Easy surface and profile grinder meets the requirements of the production environment as well as the accuracy, quick set up and change over demands of the toolroom. It also fulfils the criteria of both CNC and manual operation thanks to a GE-Fanuc control system and Jones Shipman 'Easy' software. Complex shapes, angles, radii and ultra flat surfaces can be precision ground quickly and easily.
Even inexperienced operators can obtain immediate improvements in set up and changeover times and in overall productivity for more complex work.
This is due to the combination of GE-Fanuc Touchscreen technology with Jones and Shipman's proprietary 'Easy' icon based software, which offers numerical control without the inherent complexity or cost penalties of traditional CNC systems.
In fact the 524 Easy can function as either a simple hand/hydraulic controlled machine with manual dressing and no set-up procedures or, once set using the easy-to-use 'self teach' software, can perform fully automatic dressing and grinding cycles.
With levels of functionality comparable to CNC but at lower cost all 'Easy' models are fast and simple to set-up via the touchscreen and easy-to-use Jones and Shipman icon-based software.
The control possesses the capabilities to interpolate two axes simultaneously to provide the creation of complex shapes, angles, radii and surfaces, with quick and easy set-up.
Y and Z axis control is via ballscrews driven from GE-Fanuc AC digital servomotors with 0.000004in (0.01 micron) Heidenhain 'Absolute' linear scale feedback.
On start-up, the 'Easy' control offers the operator three simple options: Manual mode, Dress mode or Grind Cycle mode.
In Manual mode the 'Easy' operates as a simple hand operated machine with hydraulic or manual table movement and handwheels for the crossfeed and downfeed which show position via a scale readout on the screen.
Work speeds and feeds are simply adjustable via the touchscreen should the operator wish to set an area grind or auto downfeed in place of manual movement once he has touched on.
Dress mode offers five standard wheel shape options flat, slot, facing, Vee form and full ISO with one or two diamonds as needed.
Dressing increments, speeds and frequency allow for roughing and finishing to optimise wheel performance.
A great feature when the full software package is incorporated is 'intelligent roughing out' of the wheel, - the system will automatically 'chop out' a basic form and then finish dress using the exact profile.
Wheel dressing can be initiated in or out of cycle and dress-on-demand for plain or complex wheel forms is provided as standard.
Dress-On-Demand allows the operator to press the Dress button at any time and the machine will stop wherever it is, dress the wheel with full compensation and return to continue from where it left off.
Grind mode allows from one to 20 grind cycles to be linked as the complexity of the component dictates including plunge, multi plunge, area (intermittent or continuous), face grind, plunge and face and multi plunge and face.
The 524 Easy has been designed from scratch to give improved productivity.
With a new bed, saddle, table, column etc, it offers increased precision, geometry and rigidity and continues a long-established tradition of excellence in manufacture.
Generously proportioned high-grade cast iron major units all combine to create greater rigidity for optimum performance in terms of grinding accuracy and repeatability.
The wheelhead slide moves vertically on low friction, preloaded ball and roller bearings, thereby ensuring extreme sensitivity, while the hand scraped table and saddle slideways are Turcite coated and lubricated automatically to reduce friction to the minimum possible.
'Sliding dogs', which are simply moved by hand without the need for tools, set the table reversal length, their positions being detected by proximity switches sited in the saddle.
Innovative design, high build quality and a rigid and stable machine structure combine to ensure accuracy and productivity and makes this the product of choice for both old and new to the art of precision surface grinding.
The 524 Easy forms the cornerstone of Jones and Shipman's all new range of Surface Grinders.

CNC cylindrical grinder improves product roundness
Accura Technics announces advancements in precision grinding applicable to aerospace, automotive, bearing and optics manufacturing. In capability tests, Accura's Model 1210G CNC grinder produced 0.000010in (0.25 micron) roundness in ball bearing outer races and 0.000006in (0.15 micron) roundness in inner races. This multi-surface grinder was delivered to the USA's Adcole Corporation (Marlborough, Massachusetts; Pompano Beach, Florida) for grinding spindle components for camshaft and crankshaft measuring machines.
Roundness of these components directly impacts axial and radial run-out of the assembled spindle.
Excellent run-out is crucial to the measuring machines' performance.
Upon inspection of the first spindle processed on the 1210G, Adcole's general manager, Patrick Cole, said, 'Needless to say, we are impressed.
And it will only get better from here.' The 1210G is equipped with a hydrostatic bearing workhead, and two wheelheads: an air bearing ID/OD spindle, and a ball bearing rotary surface spindle.
The two wheelheads are mounted on independent CNC axes.
These axes are driven by ball screws and servomotors while the X-axis is driven by a linear motor.
The three slides are mounted on a thermally stable, natural granite base.
'Customers turn to us for creative solutions to their precision grinding needs,' said Patrick Hurst, president of Accura Technics.
'We work with our customers to develop robust processes that deliver higher precision at a competitive cost which saves them time and money.' The 1210G has a 12in (300mm) swing and 10in (250mm) workpiece height capacity.
Standard X-axis travel is 14in (350mm).
Standard Z-axis travel is 12in (300mm).
The machine can be fully automated with robot loader, conveyors and gauging.
Optional features include C-axis for non-round grinding and acoustic emission monitoring system.
Accura Technics other products include the MicroTol - a machine tool platform suitable for optics machining, hard turning, shoe centerless ID grinding, and miniature bore grinding.

Entry-level tool grinding and inspection
The trio of new Walter Helitronic tool grinding and Helicheck tool inspection machines announced by Kandoumlrber Schleifring UK of Honiley near Kenilworth not only reinforces Walter's position as a world leader in the tool grinding and inspection field, but the developments also address user demands both for entry-level tool grinding and inspection equipment plus a machine specifically to grind micro tools. The new machines are: The Helitronic Basic - a budget-priced five-axis tool grinder; The Helitronic Micro - for the consistent production of tools of 0.1 mm to 12.7 mm diameter; and The Helicheck Basic - an entry-level, high-accuracy tool measurement machine. The new machines are based on similar high-quality construction principles to Walter's existing models and, likewise, also incorporate the company's renowned tool grinding software.
But importantly, the new machines feature CNC and drive hardware from Fanuc - 'ultra-reliable and globally standardised technology', says Neil Whittingham, sales director of Kandoumlrber Schleifring UK.
A derivative of the highly successful Helitronic Power, the new Helitronic Basic tool grinder offers an unrivalled route for cost-effective tool regrinding.
With Fanuc 310i CNC and 15 inch touch screen monitor, the machine features a 70 mm grinding spindle powered by 7 kW drive plus worm gear drive in the A axis.
As standard it is supplied with Walter Window Mode P1 and P3 grinding programs (end mills and drills), and options include coolant tank, Eco tool loading system, automatic clamping and worktable.
The new six-axis Helitronic Micro, on the other hand, has been developed from a clean sheet and is designed to meet the increasing production demands by, for example, the medical and electronics sectors of micro tools of 0.1 mm to 12.7 mm diameter.
Tools from 2 mm to 12.7 mm diameter can be reground.
Featuring an HSK 40, 5 kW spindle and utilising Fanuc 310i CNC that incorporates Walter's 'what you see is what you grind' Helitronic Tool Studio software, the machine's double-ended grinding head (optionally three-spindle, with one 5 kW and two 1.5 kW drives) has integrated cooling that combines with linear drives and torque motor (with integral cooling) and the machine's mineral cast base to help generate high precision, excellent surface finishes and longer wheel life.
An integrated Fanuc robot (double gripper) loading system also features, for fast - less than 10 secs - tool change, in conjunction with the four-pallet Pallet load system.
This provides unmanned working of up to 300 tools per pallet - three pallets for unground tools; one pallet 'empty' for ground tools - of tools from 1 mm to 6.9 mm shank diameter and 120 mm long.
Larger tools of 7 mm to 12.7 mm shank diameter and 120 mm long can be handled at 108 tools per pallet.
An optional, additional manual X axis is available to reduce grinding traverses, where appropriate.
The new Helicheck Basic tool inspection machine occupies 30 per cent less floorspace than the Toolcheck it replaces (by adopting vertical design principles rather than horizontal) and, like its stablemates the Helicheck and Helicheck Pro, it offers 3C Direct View camera technology with cameras for back, front and top light illumination.
The back light provides magnification of 50x, front and top of 100x; and combined with the solid granite base plate for temperature resistance and high stability, the result is a repeatability of 1.5 micron and an absolute accuracy of +/- 2.2 microns at a measuring length of 10 mm (VDI/VDE 2617: E1 = 2.2 microns + L/300).
These new machines are complemented by a new grinding wheel/electrode wheel changer for the Helitronic Power Diamond two-in-one machine for grinding/eroding PCD tools - where up to eight electrodes/wheel sets, with coolant distributor, can be changed in 10 secs - and follow hard on the heels of recently-announced the Helicheck Plus tool inspection machine for measuring standard and micro tools down to 0.1 mm diameter.

Cylindrical grinding machine finishes in one pass
The New ShapeSmart NP4 by Rollomatic is a reinforced version of the existing CNC148P4 cylindrical grinding machine with a patented method of rough and finish grinding in one pass. This machine is ideal for cutting tool blank preparation and grinding precision punches and molding components. The grinding size range is from 16.0 mm (5/8') down to micro scale, with blank length capacity up to 300 mm (12') for automatic loading and 350mm (13.8') for manual loading.
The two grinding slides have been designed with a New technology known as the BoxSlide system, which enhances stability.
To eliminate any run-out on the grinding wheels, the ShapeSmart NP4 features a New arbor system called Perfect Arbor, which uses material compression as a means of centreing the arbor into the spindles.
The NP4 also features the user-friendly tool design software, P4Smart.
With drop-down windows that allow you to edit program text and graphically check the movement of both grinding wheels during machining, it's easier than ever to grind precision blanks, punches and pins.

Super abrasive peel grinding slashes cycle times
Holroyd has employed its super abrasive machining technology to reduce the cycle time for producing turbo charger stators from 5.1/2min to just 46s. These improvements have been achieved using Peel Grinding of the stator shaft, removing as much as 5mm a side in a single cut. In addition, the super abrasive wheel used in the Holroyd process lasts up to 200 times longer than tool inserts used with in twin turret turning, providing a life of at least 10,000 parts to minimise tooling and machine set-up costs.
One of the direct results of Holroyd's expertise in helical rotor production is that the company has established itself as one of the leading suppliers to the turbocharger and supercharger industries; both as a manufacturer and supplier of high precision machine tools, and as a sub-contract manufacturer of components using the self-same machines.
Recently, Holroyd was approached by one manufacturer concerning a cycle-time problem with the machining of turbocharger stators.
The stators comprise an Iconel impeller attached to a mild steel shaft.
Previously, the time to machine the shaft, and the faces and OD of each impeller was 5.1/2 min; this being achieved using twin turret lathes.
However, there were a number of problems with this machine set-up.
First, the cycle time was too long to enable the manufacture to achieve his desired component cost.
Second, although a twin turret lathe was used to ensure full depth of cut on the shaft - without bending, this did not account for the resulting upset of the shaft during the deep machining process.
Third, the depth of cut required - 5mm a side - from the twin turret lathe, and the resulting chattering of the tools in operation, meant that the life of tool inserts was extremely poor, with commensurate high costs for replacement.
Holroyd's approach to solving these problems centred on its super abrasive machining capability: in particular the use of an Edgetek Super Abrasive Turning (SAT) Centre.
The Edgetek SAT employs CBN wheels to achieve productivity rates far in advance of those obtained with hard turning.
It is designed to remove stock from the OD of cylindrical parts (slot, groove, and forms) in all types of materials (from soft to hard) at rates 40% faster than a conventional lathe.
Because productivity with the SAT system goes far beyond that typically obtained with hard turning, the machines are ideal for machining inconel and heat treated powder metal workpieces with interrupted cuts.
They can be used for such typical turning applications as machining slots, interrupted cuts on impellers, gears, splines and facing cylindrical parts.
The use of thin CBN wheels means that the SAT machines are especially well suited to Peel grinding, where high wheel speeds and high workpiece speeds result in very high stock removal rates with low grinding forces.
Thin CBN wheels used in this way have cutting edges similar to turning tools, thereby reducing the cutting forces required between the wheel and the work piece.
Compared to conventional grinding processes, Peel grinding typically removes three times the stock with half the force within the same time frame, and allows contour-grinding of a part in the same way that conventional machining does.
Holroyd applied its SAT Peel grinding technology to the tubocharger rotors with impressive results.
The overall cycle time for machining shaft, faces and impeller OD was reduced from 5.1/2 min to just 46s - a reduction of nearly 88%.
In addition, the improved burn threshold qualities of the Edgetek SAT machine result in a lower finished surface temperature of the workpiece, which means no upset and no undesirable friction weld rings generated during the super abrasive turning process.
Finally, toolwear and, consequently, tooling and set-up costs, are much lower using the Edgetek SAT machine: the life of the CBN wheels extending to an average of 10,000 parts before re-tooling and machine set-up is required.
'We are not surprised by these findings,' said Neil English, sales director of Holroyd.
'In every case where we have performed machining trials with our Edgetek machines we have achieved at least a 40 to 50% increase in throughput, and in many cases it is much, much more.' In one recent application in the aerospace industry, an Edgetek super abrasive machine replaced seven conventional milling and grinding machines, and achieved a reduction in the throughput time for machining a highly complex and extremely hard Inconel part from 8 hours, to just 12 minutes.
English said: 'The large depths of cut and accompanying lower temperature work-piece characteristics that can be achieved with our Edgetek machines - even across difficult to work materials, are the key to achieving improved productivity, reduced process times and improved quality in highly competitive global markets.
There is no doubt that Edgetek technology is the future for machining, with the added benefit that it's available now.' Holroyd manufactures the Edgetek machines in all types and configurations to suit specific applications.

UK pressworker steps in as home supplier
Corus Europressings (Cardiff), Harlow Pressings (Cwmbran) and West Riding Pressings (Brighouse), major manufacturers of pressed metal parts for the home entertainments and white goods industries, have recently closed down, giving Clamason a golden opportunity to step in as the alternative UK supplier who can meet all the necessary quality requirements and standards. On top of that, because Sharp Precision Manufacturing (UK) do not run a press shop any more at Wrexham, Clamason is manufacturing the top and bottom RFI shielding cans for the integrated digital tuner in the latest 42in and 50in plasma TV sets produced by Pioneer GB at Castleford, West Yorkshire, for the UK and Europe. Accordingly business is booming for Clamason Industries to the extent that the company quoted for a record �20m worth of presswork, and enjoyed record sales, in the first quarter of 2006.
As its guiding principle for 60 years, Clamason has always been prepared to refocus and diversify towards new areas of technical innovation and market growth, correspondingly investing in its manufacturing facilities to fulfil those needs.
And so the acquisition of tooling from factory closures has added Thomson Broadcast UK, Panasonic and Pioneer to Clamason's customer portfolio.
Their requirements are very similar in that they all need the painted covers, bases and backplates for home entertainment systems (DVRs, Sky and Freeview boxes).
Thomson and Panasonic no longer assemble these products in South Wales but, such is demand for replacement parts (1000's per week), the contracts will add significantly to Clamason's turnover.
Clamason has been able to intervene and help these household names in part because of its successful track record of having made the original BSkyB decoder box back in the 1990's, for which major project it installed a six-station transfer press line.
Further, with its new plant now open for business at Nitra, Slovakia, Clamason is discussing original equipment manufacture with Panasonic in the adjacent Czech Republic also.

Precision metal pressings fight back
Clamason's precision metal pressings are now fighting back in all sorts of ways against plastics, providing superior solutions for many so-called 'traditional' plastics applications in the medical device sector. Accordingly, in comparison with metal pressings, plastics may suffer from shrinkage, joint line and RFI / EMI shielding problems, be degraded over time by heat, light and ultraviolet rays and hold lower dimensional tolerances. Then, unlike plastics, Clamason presswork is recyclable in 95% of cases.
The latest examples of how metals are effectively replacing plastics in medical equipment were displayed on Clamason Industries' Stand 711 at Medical Device Technology 2006, NEC, Birmingham, on February 15th - 16th.
Clamason Industries takes great care to safeguard customer confidentiality, so therefore cannot detail the growing number of medical devices incorporating its pressed metal, precision components, which go well beyond the more traditional pressed scalpel blades, pins, rods and implants.
Clamason Industries can, however, quote the capabilities and procedures which the company has in place to ensure that its engineering solutions meet the exacting standards demanded of medical device protocols.
In fact 50% of the cost of a medical component can be its validation cost.
Accordingly, all Clamason medical components are fully process validated using Design, Installation, Operational and Production Qualification protocols (DQ / IQ / OQ / PQ).
In addition, the Clamason team is trained in the use of URS (User Requirement Specifications), CAPA (Corrective and Preventative Actions) and GMP (Good Manufacturing Practice).
The new �40,000 Simac Masic 3D realtime vision system at Clamason measures and monitors in 3D 100% of thin and intricate healthcare components fed from a high-speed press in a continuous strip and requiring measurement of key features to 50-micron tolerances.

Partnership makes quality medical components
Close co-operation at all stages between three companies Clamason Industries, Bruderer UK and Simac Masic has provided an exemplary engineering solution for a critical small precision component which exceeds the exceptionally stringent quality requirements of an international healthcare OEM. The growing number of medical devices incorporating Clamason's precision pressings go well beyond the more traditional pressed scalpel blades, pins, rods and implants. All Clamason medical components are fully process validated using Design, Installation, Operational and Production Qualification protocols (DQ / IQ / OQ / PQ).
In addition, the Clamason team is trained in the use of URS (User Requirement Specifications), CAPA (Corrective and Preventative Actions) and GMP (Good Manufacturing Practice) - all essential for medical industry approvals.
In this particular application, Clamason's new, state-of-the-art, �200,000 Bruderer press, model BSTA 250-75B, integrated with a decoiler and crop-off station, runs in a dedicated cell at high speeds of up to 800 strokes per minute, producing two parts per stroke.
The 25-tonne, PLC-controlled, Bruderer BSTA Series press has a bed length of 750mm and features quick-change tooling for JIT manufacture.
Plantmaker Bruderer is a world leader in stamping technology and a byword for precision, with a famous 60-year history dating back to its foundation in 1943 at Frasnacht, Switzerland, where Clamason's engineers were trained comprehensively on the new machine.
Most spare parts are held conveniently in stock at the Luton headquarters of Bruderer UK, who offer an impressive door-to-door service within 24 hours.
A �40,000 Simac Masic 'Stampede' 3D realtime vision system ensures zero-defect production of the intricate and highly toleranced healthcare components which are fed from this press in a continuous strip.
A world away from the previous UK-wide system of sample-based inspection, which was based upon periodic checks and charts of trends, the in-line inspection of 100% of the thin metal parts requires the measurement of four key features to a 50-micron tolerance.
For example, to analyse height characteristics, the system measures and monitors each component in 3D from the side.
A standard vision system can only measure in two dimensions but, by developing an innovative arrangement of a second camera, light and product strip, third-dimension features can also be checked with the required accuracy and repeatability.
In other applications for the Bruderer BSTA 250-75B, ten or more components can be stamped out per stroke at over 1000 strokes a minute and, if four or five measurements are required per part, the Simac Masic 'Stampede' inspection system has to perform up to 50,000 measurements per minute ! The company Simac Masic has been working since 1992 as an integrator with PPT Vision of Minneapolis, where their hardware and operating system are produced.
In addition, the Clamason team is trained in the use of URS (User Requirement Specifications), CAPA (Corrective and Preventative Actions) and GMP (Good Manufacturing Practice) - all essential for medical industry approvals.
In this particular application, Clamason's new, state-of-the-art, �200,000 Bruderer press, model BSTA 250-75B, integrated with a decoiler and crop-off station, runs in a dedicated cell at high speeds of up to 800 strokes per minute, producing two parts per stroke.
The 25-tonne, PLC-controlled, Bruderer BSTA Series press has a bed length of 750mm and features quick-change tooling for JIT manufacture.
Plantmaker Bruderer is a world leader in stamping technology and a byword for precision, with a famous 60-year history dating back to its foundation in 1943 at Frasnacht, Switzerland, where Clamason's engineers were trained comprehensively on the new machine.
Most spare parts are held conveniently in stock at the Luton headquarters of Bruderer UK, who offer an impressive door-to-door service within 24 hours.
A �40,000 Simac Masic 'Stampede' 3D realtime vision system ensures zero-defect production of the intricate and highly toleranced healthcare components which are fed from this press in a continuous strip.
A world away from the previous UK-wide system of sample-based inspection, which was based upon periodic checks and charts of trends, the in-line inspection of 100% of the thin metal parts requires the measurement of four key features to a 50-micron tolerance.
For example, to analyse height characteristics, the system measures and monitors each component in 3D from the side.
A standard vision system can only measure in two dimensions but, by developing an innovative arrangement of a second camera, light and product strip, third-dimension features can also be checked with the required accuracy and repeatability.
In other applications for the Bruderer BSTA 250-75B, ten or more components can be stamped out per stroke at over 1000 strokes a minute and, if four or five measurements are required per part, the Simac Masic 'Stampede' inspection system has to perform up to 50,000 measurements per minute ! The company Simac Masic has been working since 1992 as an integrator with PPT Vision of Minneapolis, where their hardware and operating system are produced.

Ultra high precision medical pressings in the UK
A not so traditional Black Country 'metalbasher' is now manufacturing five precision metal pressings for Pfizer's revolutionary new insulin dispense system and providing a service to other international customers, too, as a World-class supplier to the medical industry. Pfizer's device for pulmonary delivery is claimed to provide the first non-injectable form of insulin available since the discovery of the drug in the 1920's. As its guiding principle for 60 years, Clamason Industries of Kingswinford near Stourbridge has always been prepared to refocus and diversify towards new areas of technical innovation and market growth, correspondingly investing in its manufacturing facilities to fulfil those needs.
In three years up to the end of 2007, the leading-edge medical industry will have grown from a negligible amount to some 30% of the company's turnover, second in value only to its first-tier automotive engineering contracts.
Clamason's five pressings - two in 5052 grade aluminium alloy and three in 301 grade stainless steel - are for Pfizer's ground-breaking insulin delivery system via the lungs.
It dispenses a dry powder, synthesized insulin called Exubera, the first inhalable insulin set to become available on the mass market.
Exubera is inhaled before taking food and acts rapidly and effectively.
Pulmonary delivery has been in development for a number of years.
It offers a potential alternative to injections, which may subject diabetes patients (including the many needle phobics) to risk and discomfort.
Reducing a reliance on subcutaneous injection is more patient compatible, clearly lessening pain and the possibility of infection.
The charity Diabetes UK estimates that 2.1 million people in Britain have the condition.
It is reckoned that nearly 230 million people worldwide have diabetes, and the global figure is expected to rise to 350 million by 2025.
If uncontrolled, diabetes can lead to a number of complications including blindness, heart disease, stroke, kidney failure and nerve damage.
Already the complications of diabetes cost the NHS approximately �5 billion a year.
The new device allows adult patients with Type 1 and Type 2 diabetes to breathe in their insulin as powder from a handy blister pack rather than inject it.
The action of loading the drug primes the pump, so that no propellant is necessary.
Appliance and molecular powder formulation - including ironically the use of sugars to carry the drug - were developed by designers Nektar Therapeutics (www.nektar.com) for the Exubera insulin produced in a joint development program between the pharmaceutical giants Pfizer and Sanofi-Aventis.
It is now manufactured and sold exclusively by Pfizer.
The plastic injection mouldings are made and final assembly of the Exubera inhaler is performed by Clamason's UK customer, Bespak plc at their custom-built facility in Milton Keynes (www.bespak.com), and US customer, the Tech Group, Inc which includes a 50,000 sq ft, contract injection moulding facility for medical products at Tempe, Arizona (www.techgroup.com).
Bespak, a fast-growing British technology company, is quoted on the London Stock Exchange and has been providing dispense solutions for the pharmaceutical, medical, health and personal care sectors for more than 40 years.
As a World leader in the production of pressurised metered dose inhalers, Bespak's appointment as principal contractor on the Exubera inhaler project was an obvious one.
The five Clamason pressings in the Exubera device are as follows.
Manufactured in 5052 grade aluminium alloy are a mainframe assembly (with two stainless steel studs outsourced and assembled by Clamason) and a link pump handle.
In 301 grade stainless steel come three further parts - a blister retainer, a customised flat washer (replacing an off-the-shelf version) and a transjector punch.

Pioneering shielding can for TV sets
Privately owned British precision pressings manufacturer Clamason Industries of Kingswinford, West Midlands, is manufacturing a top and bottom RFI shielding can to house the digital tuner integrated into the latest 42in and 50in plasma TV sets being made for the UK and European markets by Pioneer GB at Castleford, West Yorkshire. The cover of tin-plated and the base of zinc-plated mild steel are essential for picture quality to shield against radio frequency interference (RFI) and electromagnetic interference (EMI). Clamason delivers the RFI screening cans in pairs on a JIT basis to Pioneer GB, always filling a timed delivery slot on a specific day.
Meanwhile plasma screens are flown in from one of the Pioneer Corporation's three plants in Japan for the sets to be built at Castleford - at a daily rate of up to 1800 units, 75% of which are expected to consist of the state-of-the-art 42in model.
The highly successful British operation employs 400 workers in a 12,000 sq ft factory and runs three assembly lines working 24/7, as it strives to meet the fast-expanding demand from retail and business sectors for the Pioneer and NEC brands which it manufactures.
Pioneer came to Clamason Industries as an alternative UK supplier able to meet all the necessary quality requirements and standards when their previous supplier Sharp Precision Manufacturing (UK) shut down its stamping operation at Wrexham.
In fact the current wave of press shop closures across Britain has meant that business is booming for Clamason, to the extent that this 'lean manufacturer' has quoted for a record �20m worth of presswork, and enjoyed record sales, in the first quarter of 2006.
Clamason has been able to intervene and help household names like Pioneer in part because of its successful track record of having made the original BSkyB decoder box for Pace in the mid-1990's, for which major project it installed a special Chin Fong Worcester transfer press line from Taiwan.
That line of six presses located together provides rapid transfer of pressings between stations by pick-and-place robots with careful handling.
The system allows the manufacture of highly complex parts with no carry strip and the automatic insertion of other components and has the facility to reverse the burr side automatically within the process.
It is ideally suited to complex and intricate set top box applications where the maintenance of excellent surface quality is an essential consideration.
Above and beyond other home entertainments uses (such as DVR bases and Sky and Freeview boxes) for Thomson Broadcast UK and Panasonic, Clamason makes similar RFI shielding components for automotive multinationals.
Those pressings are engine control unit (ECU) enclosures for its first-tier customers Delphi Worldwide (on a variety of vehicles assembled in Europe, Asia and Central America), Motorola ACES (soon to become Continental AG) in North America and France, and Hitachi Europe (on the Nissan Micra and Renault Clio).
Furthermore, in order to ease JIT deliveries to the Central European factories both of automotive first-tier suppliers such as Delphi and TRW and of home entertainments OEMs such as Panasonic and Thomson, Clamason Industries has opened a 10,000 sq ft satellite plant with a �300,000 investment at Nitra, on the motorway network 80km east of Bratislava, capital of Slovakia.

Heat exchanger benefits from welding technique
Carr's Welding Technologies have developed a welding procedure for the manufacture of a flat heat exchanger for A K Industries . The Under-shower-tray-heat-exchanger takes out heat from the waste-water from the shower and pre-heats the cold water coming in to the shower, thus saving money and energy, of course. Carr's make the 4 part heat exchanger on their big Trumpf CW robot welding laser, which welds the 2 thin sheets of stainless steel together.
The complicated path welded into the sheet is then subject to a further process to create a lattice of water ways.
Mains cold water is fed through this heat exchanger and the warm waste water from the shower flows over the surface.
This has the effect of pre-heating the incoming water so that the instant shower element does not have to work as hard.
Thereby reducing energy consumption by the shower.
The Development programme carried out by Carr's over the summer, has perfected the art of jigging and welding the thin steel sheets together, so that good penetration is achieved all round the part.
Running at 2.5metres per minute the 5 metre weld path is welded in under 2 minutes.
The product is then leak tested and then packed for shipment to A K Industries of Hereford who complete the heat exchanger with the plastic surround and all the fittings.
This simple patented design, has been entered into a national competition for best energy saving product of the year and has been short listed for the final round of judging.

Versatile rods gas-weld non-ferrous metals
Versatile rods gas-weld non-ferrous metals As well as gas-welding welding aluminium, welding rods can be used to weld almost all other non-ferrous metals and alloys - and galvanised steel and between dissimilar non-ferrous metals. Welding aluminium, usually a difficult task requiring expensive equipment and high levels of skill, is fast and straightforward with the revolutionary new Durafix Easyweld aluminium welding rods from Durafix. In addition to aluminium, the rods can also be used to weld almost all other non-ferrous metals and alloys - they can even be used to produce strong welded joints in galvanised steel and between dissimilar non-ferrous metals.
No special equipment is needed to make welds with Easyweld rods - their low working temperature of just 392 deg C means that they can be used in conjunction with almost any ordinary hand-held blow torch.
For the convenience of new users, Durafix offers the rods in the form of inexpensive kits, complete with a high-quality auto- or manual-ignition torch.
For users who already have a suitable torch, Easyweld rods can also be purchased separately, in a wide range of pack sizes.
Despite their convenience and ease of use, Easyweld rods produce dependable non-porous joints which are stronger than the parent metal, and which are entirely free from slag.
The quality and performance of the rods is confirmed by the US Army Engineering Corp, which has approved them under specification number MIL-R-4208 for use in an extensive range of military applications, including the repair of aircraft skins.
Among the many other applications for Easyweld rods are aluminium boat repair, which is usually impossible with conventional processes because of the thin gauge of the metal used for boat hulls; repair of die-cast components, which is also in most cases uneconomic by conventional means; and the maintenance of radiators, heat exchangers and cooling systems.
Because there are no toxicity hazards associated with the Easyweld process, it is equally suitable for use in domestic, workshop and industrial environments.
Whatever metals are being joined, the unique formulation of the Easyweld rods completely eliminates problems with oxidation at the weld, without the use of flux.
Not only does this mean that dependable joints can be readily produced even by users with no previous welding experience, it also avoids the environmental problems associated with the aggressive flux materials used in many other welding processes.
As well as being simple, safe and convenient, Easyweld system is also exceptionally economical.

Powerful portable machine bevels plate edges
Model SKF 2023 is the most powerful of a range of seven portable chamfering and bevelling machines available from Surtech. With its 2,5kW electric motor, variable cutting speed from 6500 - 8500 rev/min and the multi-bladed milling head it is the ideal machine for bevelling plate prior to welding. A large bearing guide on the end of the milling head and a large disc support make it easy to move the machine along both straight and contoured edges.
Bevel widths of up to 15mm at 30, 45 and 60 degrees are possible and with the correct choice of milling head and carbide inserts the machine will handle mild steel, stainless steel and aluminium.
Slightly hardened edges from thermal cutting are no problem.
Unlike standard bevelling machines which have milling heads with between one and four inserts Model SKF 2023 has a unique and patented milling head with two rows of eight inserts.
As a result metal removal rates are several times faster and the finish is smoother and more consistent.
Model SKF 2023 comes close in performance and results to dedicated bench and stationary bevelling machines with the benefit of costing considerably less and being more versatile.

Self-propelling bevelling tool prepares plate
Surtech's Model 800 is used for high speed weld preparation of mild steel, stainless steel and aluminium plate from 5mm to 40mm thick. The 100mm dia. rotary shearing tool is driven by a 1,5kW, 2800 rev/min motor and operates virtually without noise at feed speeds up to 1500mm per minute.
It lasts up to 2000m, depending on bevel widths and material.
When worn it can be re-sharpened.
The max.
bevel width is approx.
15mm at angles from 15 to 50 deg.
While bevelling the machine propels itself along the edge of long plates without any effort by the operator.
Model 800 will also hold smaller parts without the operator having to support it.

Cranable unit cuts plate edge bevels in-situ
Model ASO 900 bridges the gap between portable and stationary bevelling machines. When parts are too large to handle and required bevels too wide for portable machines Model ASO fits the bill. At approx.
85kg it needs to be lifted into place with the help of a crane but once in position it is self propelled and can easily be controlled manually.' For smaller parts it can be mounted on a wheeled carriage allowing parts to be hand fed.
The powerful 2.2kW motor combined with the 63mm diameter milling head will bevel mild steel 8mm wide in a single pass and up to a max.
of 40mm wide in several passes.
Feed rate is approx.
600mm/min.
Bevel angles are adjustable from 15 to 45 degrees.
Model ASO 900 uses milling cutters to produce smoother bevels than machines with rotary shearing tools.
Surtech offer more than a dozen portable, transportable and stationary machines for producing bevels prior to welding.

Portable weld prepping tools produce 15mm bevels
Surtech's SKF range of portable bevelling tools is claimed to be the fastest and most powerful available anywhwere. Whilst traditional bevelling tools have milling heads with 2 or 3 carbide inserts set at a fixed 45 degrees, SKF tools feature patented milling heads with 5 inserts at angles of between 10 - 80 degrees. As a result SKF tools will bevel up to a width of approx.
6mm in a single pass and up to a max.
of 15mm in three passes.
Faster and with a smoother finish than any other portable bevelling tool.
A 140mm dia support disc and a 28mm dia bearing guide allow accurate tracking of straight and contoured edges as well as holes with a min.
dia of 30mm.
There are five machines in the SKF range.
With motors from 1.2kW To 2.6kW, some with variable speeds suitable for all metals from aluminium to mild steel and from stainless steel to tool steels.
SKF machines can be viewed and tested at Surtech's Abrasive Test Centre or demonstrated in your works.

Plate machining systems combined in one
TIPO B251 is an automatic CNC line for the processing of plates of medium to heavy thickness. Its working range is very wide and goes from punching, drilling, milling and pointing to marking and shearing (also in shapes) using oxy-fuel gas cutting and plasma-arc cutting systems. The plates are processed in a single step, so performing several operations automatically reduces working costs and material handling.
Polygonal or shaped plates are processed with accuracy at reduced production costs.
TIPO B251 can process plates up to 2540mm wide and 6000mm long (longer lengths are optional).
The hydraulic punching unit is fitted with a single punch and an automatic plate hold-down.
The line can profile shapes and they can be automatically unloaded using a device with a capacity of 2500mm x 500mm.
The TIPO B251 is an upgraded version of Ficep's earlier TIPO B machine and has the following innovations: * Punching operations are performed using a punching tool with punch, die and positive stripper integrated such that the best punching quality is achieved.
The circular stripper holds and clamps the material evenly and constantly.
* The line can be fitted with an automatic tool changer having four, eight or 14 tool holders in a shuttle system.
* Thanks to the use of special valves, the punching cycle is very fast - reaching 1s/cycle.
* The line can drill (also combined with oxy-fuel gas cutting) plates up to 100mm thick (minimum thickness is 6mm).
It can process plates up to 10 tonnes and punch up to 25mm thickness (also combined with plasma-arc cutting).
These features are assisted by the design of the roller ways and the 'master' and 'slave' carriages, which are electronically synchronised, thus keeping the feeding of the plate always aligned along the X-axis.
In this way, it is possible to process with accuracy bent plates and plates with uneven edges.
* It is possible to perform milling operations not only inside the shaped plates but also along their external profile, to produce bevels for weld preparation.
* The datum line can be programmed according to needs and does not need any horizontal hold-downs.
* Thanks to the plasma-arc cutting system - a modified Hypertherm HT 2000 HS system - it is possible to reach cutting speeds 20% higher than earlier machines and the TIPO B251 achieves a considerably better cutting quality.

Portable unit cuts tube precisely on-site
Orbimatic (UK), the manufacturers of high quality automatic welding equipment have introduced the PS 4.5 Tube Cutting Machine into their product range which has been designed and developed for on-site use. The PS 4.5 is manufactured by Georg Fischer Piping Systems and works using the same 'Orbital Cutting' principle as the industry proven RA range of cutting machines. All Georg Fischer cutting machines use variable speed high powered motor units with a rotating carbide cutting blade to give high precision cut.
This system allows the PS 4.5 to be used prior to Orbital Welding application with no extra preparation work need on the tube end.
A simple cam system is used to introduce the cutting blade into the tube accurately and gently prior to the cutting process.
Because the cutting blade is introduced to the material gently its life expectancy will be extended.
Weighing in at only 19kg, the PS 4.5 is ideal for applications where it needs to be transported form one working area to another.

3D cutting system machines weld preps
Boiler making demands the assembly of complex components, but before this can be carried out all parts must be prepared as accurately as possible. Three dimensional parts such as pipes and dished ends can be particularly difficult and for high quality bevel and profile cutting of these components, ESAB Automation has introduced the VBA Wrist. This innovative 3D process technology can also be used for both normal 2D vertical weld and edge preparation of steel plate.
By totally eliminating manual measuring and manual cutting, as well as reducing workplace handling and post cutting operations, the VBA wrist will appeal to all boiler makers.
In combination with ESAB's Vision Control, extremely small bevel tolerances can be achieved and due to its compact design and low weight, the VBA Wrist can be used with the ESAB Suprarex SXE-P cutting machine.
The VBA Wrist operates on a new patented principle.
In contrast to conventional systems, the tool centre point (TCP) of the VBA Wrist remains fixed in space during swivelling.
Its high accuracy adapts perfectly to every cutting task and its integration into CNC cutting machines provides uncomplicated control of the cutting process.
Cutting parameters are automatically set for various material thicknesses as well as bevel angles, significantly reducing programming requirements.
Exactly repeated cycles in bevel cutting for X and Y cuts provide the highest cutting quality even on complex geometrics.

Quality centre lathe price cut by 40%
The latest 'special edition' Triumph VS2500 variable speed centre lathe is now available from Colchester Sales from just GBP 12,750 a massive price reduction of 40 per cent from the previous model. Based on a world-wide resurgence in the conventional manual machine market for Colchester Lathe and extensive value engineering, the new Triumph has a 7.5kW motor with triple range, variable speed drive giving 14 to 2,500 revs/min. It has a 400 mm swing over the 1250mm long hardened and ground bed and has been regarded internationally as the 'best-known' model of centre lathe.
The machine weighs in at a hefty 1,610kg in standard trim which demonstrates the inherent rigidity of the basic machine design and potential for high accuracy turning tasks.
The price reduction is a result of a swing to traditional centre lathe manufacturers such as Colchester Lathe due to problems of long-term reliability, poor spares and service support and disastrous residual values associated with low cost suppliers over the last five years or so.
This has enabled Colchester Lathe to respond to rising demand especially in workshop, education and training schools and instigate value engineering and competitive sourcing to maintain the level of quality associated with the brand name and make it more affordable.

Demand for centre lathes brings prices down
A dramatic turnaround in the demand for conventional lathes has enabled a lathe builder to reduce the price of selected models in its centre lathe range by up to 40 per cent.
A dramatic turnaround in the demand for conventional lathes which has improved the benefits associated with economies of scale has enabled Colchester Lathe to reduce the price of selected models in its centre lathe range by up to 40 per cent. The new pricing structure is in response to Colchester Lathes' distributors reporting a world-wide resurgence of training schools and workshops who are preferring to buy known brands such as Colchester. This follows bad experiences such as long-term reliability, poor spares and service support and disastrous residual values that are a growing problem associated with the newer breed of low-cost centre lathe suppliers.
The effect of the market shift in Colchester's favour is qualified by a recent surge in demand where some GBP 750,000 worth of centre lathes have been ordered from seven different countries in the Far East, America and Southern Ireland.
According to Sales Director, Mike Dawes: 'Sales of our traditional centre lathes have experienced a dramatic turnaround.
This has motivated us to rationalise machines in the range and certain key component parts while maintaining or improving quality of build.
With orders rising, we have been able to instigate value engineering and more competitive sourcing which also capitalises on the efficient production methods that are well-proven on our two and three-axis Tornado CNC lathe range.' Over the last five years or so, Colchester Lathe has grown its market share with its CNC range of slant bed Tornado and the Combi combination lathe.
Says Mike Dawes: 'Now with the new economies of scale, we have justified a total re-focus on our conventional machines which has resulted in a massive 40 per cent reduction in price on selected models.' When this is added to the world respected name of Colchester, built-up from over a century of centre lathe manufacture and being Europe's biggest lathe builder, distributors have already responded with a growing order book.
