Connector parts are produced within tolerance and at lower cost on a CNC sliding head automatic and economical batch sizes are 200-off and less.
A recent convert to CNC sliding-head mill-turning, Hampshire, UK subcontractor Croft Engineering supplies a local electronic equipment manufacturer with connector parts that were previously produced by another contract machinist in the UK to a lower standard on cam automatics. For years the customer thought that the poor quality was normal; then it approached a subcontractor in India to try to obtain a better price and was disappointed at the quality of the samples that came back. The parts are now produced within tolerance and at lower cost on Croft's multi-axis Star SR-32J sliding head automatic lathe, according to Jason Mortara, joint owner of Croft with his parents, Paul and Judy.
Furthermore, economic batch size is down to 200-off or less and delivery is fast, factors that are of considerable benefit to the customer, as it specialises in bespoke electronic instruments for niche markets.
The arrangement has worked so well that in the first seven months, over 50 different styles and sizes of connector from 6 to 16mm diameter and up to 30mm long had been produced on the Star.
What was originally envisaged as GBP 15,000 of business annually will in the 12 months to March 2007 be at least double that figure.
So pleased is the customer that its proprietor has written a letter to Mortara stating, 'The improved quality and delivery times from Croft, together with keener prices, have enabled us to give a better service to our existing clients and to gain new business from our competitors.' Croft found that there was little money to be made using its manually operated machine tools, so a few years ago the company invested in a CNC chucking lathe and milling machine.
However, staff costs were high because most parts still needed subsequent operations, and overheads such as rates and electricity were climbing.
Competition was fierce and profit margins remained slim.
It became obvious that a change of direction was needed.
Enquiries were being received for components that were more suitable for sliding-head machining.
So a study was carried out which showed that the best lathe for the type of work under discussion was the Star SR-32J.
An investment of over GBP 100,000 in a machine tool is a big step for a family-owned company, but Croft was getting all the right signals from potential customers, such as the electronic equipment manufacturer which happened to call in for a simple manual job to be done, and a press shop in Oxford that needed low cost, threaded inserts in quantities of 4,000-off.
Discussions with these two prospects, coupled with on-going machining of concrete drill adapter components up to 32mm diameter for another party, eventually persuaded Croft to take the plunge.
A second-hand sliding head machine was rejected, as Croft was new to the technology and needed the reassurance of having a comprehensive service package including warranty, cycle time estimates, programs, training, tooling advice and telephone helpdesk.
'All have been readily forthcoming from Star GB,' said Paul Mortara.
'It has been a very good experience.
We were comfortable with the Star lathe, Fanuc control and FMB bar magazine three months after installation - earlier than we thought.' He added: 'Star even recommended the finance house, which was able to offer good terms as it is familiar with the higher-than-average residual value of the machines.' Since the SR-32J was installed in March 2006, the situation at Croft Engineering has been transformed.
Few subcontractors in the area have such a capable mill-turning facility, so competition is much less.
Once set, the bar-fed machine works around the clock with minimal attendance during the day and unmanned overnight, turning out top quality components.
Paul Mortara sums up the advantage of the SR-32J using the example of the concrete adapter parts that the firm has been making since 1993.
Initially the components were machined entirely manually; then using the CNC chucker followed by manual drilling, tapping and hexagon milling on three separate machines; and finally in automatic, 'one-hit' cycles on the Star.
Where it used to take approximately 40h to machine a batch of 500-off, it now takes a third of the time with very little manual intervention, added to which quality is greatly improved.
Full use is made of the SR-32J's capabilities.
Tolerances within 10 micron are routinely held, whereas that was far more difficult on Croft's other production plant.
All parts are transferred to the opposed sub spindle for reverse endworking and around half undergo driven tool operations.
Of the other 50% of components, some can be extremely simple, prompting people to suggest one does not need a CNC slider to produce them.
Croft's experience is that these are machined just as cost effectively as more complex parts.
Jason cited the example of valve guides they produce in various sizes for classic cars.
Each guide requires only a short cycle, but all are very price-sensitive.
The job was referred from another subcontractor that was unable to be competitive.
Croft's view is that even if a majority of work is relatively simple and only the occasional part requires a complicated machining sequence, there is no problem justifying the purchase of a CNC sliding head automatic.
Unit production cost will always be an issue for customers, yet a subcontractor must be able to amortise a machine tool over a reasonable period.
One method that Croft uses to assist in meeting these conflicting needs is to suggest to a customer that design changes are made to a component so that it can be produced in a shorter cycle time on the Star, and perhaps in one operation rather than in two or three.
Another cost-down technique is to offer to fulfill a non-urgent order during the following week, say, when the correct size and type of bar is scheduled to be in the magazine.
This saves set-up time and reduces the price per part.
Paul Mortara concluded by commenting, 'Manufacturers in the UK often do not want to have their components made abroad, but feel that they are forced to by customers demanding ever lower prices.
Now there is another option to consider.' He said: 'Highly automated, multi-tasking machine tools like the Star are the answer to keeping work in Britain.
We will probably buy a 16mm or 20mm model next, which will be even more economical at producing smaller parts and increase our competitiveness further.'

Powered spindles and complex machining
The MultiAlpha 8x20 and 6x32 machines with their powered spindles and complex reverse face machining capability are well suited to machining complex components in a single operation.
The ongoing product implementation strategy for multi-spindle turning units at Tornos is progressing in giant steps. The recently launched MultiAlpha 8x20 and 6x32 machines with their powered spindles and complex reverse face machining capability are well suited to machining complex components right through to completion in a single operation. To enhance this capability even further, four additional units are being fitted to the new machines with immediate effect.
The first of the new innovations is the Y axis on the slide-rest.
This is an ideal addition for manufacturing complex components as it simplifies challenging operations such as offset transverse bores, the milling of surfaces with transit functions, the milling of slots and the deburring of transverse bores.
An extensive and diverse range of macros are provided to make these functions easy to program, giving the end user the immediate benefits.
The Y-axis on the slide rest has a 12mm stroke with a torque of 1.5Nm delivering a maximum speed of 8,000rpm.
For customers requiring more speed, a 0.75Nm unit is available to deliver 16,000rpm with gearboxes being readily available to enhance spindle speeds further.
The Y axis frontal unit is an option that exists in two versions - one as a driven unit and the other one not driven.
The non-driven unit is used primarily for internal machining.
This makes it possible to perform processing steps directly from the front, which were previously carried out using the slide-rest.
This leaves the slide-rest free to perform other machining operations simultaneously.
Here too, macros can be employed for operations such as internal thread whirling to simplify the task.
The second variant takes the form of a frontal Y axis with drive unit.
Complex components frequently require several drilling operations from the front with relatively narrow diameters.
This equipment is ideally suited to this purpose.
Thanks to the powered spindles, bar stock can be positioned virtually anywhere.
This unit, like the Y axis on the slide rest has 1.5Nm of torque with a maximum speed of 8,000rpm with the option of a 0.75Nm unit with a maximum speed of 16,000rpm.
The new transverse drilling unit is proving to be the icing on the cake for Tornos customers.
It is a small and powerful unit that can be fitted in any position without problem thanks to its intelligent symmetrical design.
This equipment can be retrofitted to existing MultiDECO units as well as the new MultiAlpha 8x20 and 6x32.
The modularity of this unit is further enhanced by equipping it with a diverse range of heads, either in the form of a direct drilling unit or with a 90 degree head for performing lateral drilling/milling operations.
The drill has 2Nm of Torque with a maximum speed of 8,000rpm, however there is the option of a gearbox that will provide a torque output of 10Nm with a maximum speed of 1,250rpm.
With these standard items of equipment, Tornos is consistently striving to enhance its multi-spindle product strategy, enabling complex components to be machined through to completion in a single fixture setting.

CNC 8mm bar automatic lathe has live tools
An 8mm capacity, single spindle, CNC automatic lathe now has a motorised unit to power live tooling and there is also an option of a workpiece conveyor with the machine.
The world's first 8mm capacity single-spindle, automatic lathe with tailstock - the Deco Sigma 8 (Previously Deco 8sp) from Tornos has undergone product enhancements. Since its launch in 2005, the highly successful Deco Sigma 8 with five basic linear axes now incorporates a motorised unit for live rotary tools and a workpiece conveyor belt to deliver additional productivity options for customers. The new motorised unit enables the user to install a front-mounted and a rear-mounted live rotary tool for simultaneous main and counterspindle operations respectively.
This allows customers to conduct drilling, face milling on or off axis, tangential milling on the diameter with polygon cutting, thread whirling and thread milling currently being researched.
This development brings significantly improved capability to the Deco Sigma 8 allowing customers to achieve relatively complex component manufacture without the cost of a high specification machine.
This development enables the workpiece to be machined on its front and rear faces within compact dimensions whilst retaining every tool position.
It also allows rotational speeds to be set digitally as it is powered by the same S11 motor used to drive transverse spindles.
This new development has a maximum rotational speed of 10,000 rev/min and is suited to ER8 collets with a maximum 5mm tool shank diameter.
The unit can be mounted right at the back of the tool system X1/Y1 and can replace the 'L-shaped' tool support for 2 x 4 fixed turning tools (front and back).
Whenever this equipment is being employed, an 'L-shaped' bracket can be mounted to hold 6 fixed-position axial tools, three at the front and three at the back.
* conveyor system - the Deco Sigma 8 developed from extensive market research enables Tornos to address markets such as the electronics and medical.
The second development, the workpiece conveyor belt lends itself to these specific sectors and enables customers to enhance productivity and simplifies post operation handling of components.
This option enables workpieces to be conveyed from the workpiece separating unit, which is located outside the machine.
The machined workpieces are collected in a perforated tray and when another sorting system is used such as a turntable or a bucket distributor, a workpiece slide can be mounted in place of the tray.
The conveyor belt enables the end user to remove workpieces safely with a conveyor belt speed that can be adjusted to suit the work cycle.
The belt feed rate is fully adjustable and can operate from 1.2 to 21m/min.
This unit can be adapted to work with the customer's choice of external workpiece retrieval and sorting system, making it a truly universal system.

CNC automatics replace cam-driven lathes
Replacing cam-driven automatic lathes with CNC sliding head automatic lathes means a couplings maker can benefit on delivery and price and run machines 'lights out'.
The replacement of cam-driven turning with high-technology citizen cnc mill/turning machines has given John Elliot, the 83-year-old managing director of Quality Couplings, a new lease of life. 'The new machines have transformed the company,' he said, 'Giving me completely renewed interest - you could say I've developed a totally new outlook on life.' Following the installation of two Citizen C-Series CNC sliding head automatic lathes Elliot reflected: 'One immediate benefit of CNC technology is that we know exactly where we are with production, quality, delivery and price, and the company is already benefiting from reduced cost of production per part as the new machines are run unmanned at night.' That's a 'far cry' from the situation 12 months ago when he was facing the spectre of a future lack of skills for his traditionally bread-winning, but ageing, cam-driven machine based turning operation as four of his key autosetters (with 75 years service between them) look forward to retirement next year. He decided then it was time for a change and to adopt high technology mill/turning.
After spending some time looking at the leading CNC sliding head machines on the market, he decided in 2005 to buy the two Citizen C-Series machines from NC Engineering in Watford, UK.
These were installed in a refurbished factory unit just four units away from his cam machine shop and arrangements were made for NC Engineering to retrain an autosetter, Dave Reynolds, (who can tell the tales of some 50 years of being around automatic lathes) while 26-year-old CNC setter/operator, Paul Holliman, was recruited to run the new Citizen C16-VII and C32-VIII machines.
Born in 1923, Elliot left school at 14 to serve a seven-year apprenticeship as a pattern maker, followed by several years in the Merchant Navy during the war.
When he was 58, he bought Quality Couplings from The Receiver - at a time when many would rather be thinking of retirement rather than building a business - and moved the company from Birmingham to its current base in High Wycombe, Buckinghamshire.
He set about using traditional cam autos to produce turned parts for pipe fittings, and over the years progressively built a very successful business.
Today, he runs the two machine shops from an office on the shopfloor.
He wakes at 5 am every morning, arrives at work by 7 am and most evenings leaves at 4.45 pm on the dot.
In March next year, he is due to be featured in a Channel 4 television documentary.
Quality Couplings has a customer base of some 600 clients spanning heating and ventilation, gas burner, valves, pipe and hose fittings, pneumatics, heating, hydraulics and automotive suppliers, and it manufactures batches ranging from 500 to 10,000 parts.
CNC machining now takes priority at the firm ('Once established with the Citizens we despatched 11 cam machines to a company in Birmingham,' he said) though six cam machines continue to be used.
However, capability to mill and turn parts of various levels of complexity in a single operation is dictating as much work as possible through the Citizen C16 and C32.
This is confirmed by Holliman, who reckons over 700 programs have been written since the machines were installed in April 2005.
Machines are often reset in the afternoon ready for the next job to run through the night and when the batch is completed, the machine switches off and is reset in the morning for the next part.
Due to the wide variety of batch sizes Holliman prefers to program at the machine while its running, working to the scheduled work load laid down by Elliot.
Far from sitting contemplating his life, Elliot is continuously busy.
He still goes to see customers, takes most of the phone calls to Quality Couplings and ensures all the machines are fully loaded with jobs.
'I issue the job cards manually - but early in 2007 we will be computerised, which will also help me control stock,' he said.
Computers will be an important addition to the citizen machines as with such a large customer base and a big demand for production call-off from stores for quick delivery, Quality Couplings has around GBP 1 million of finished stock components.
Other tasks performed by this most senior of managers is the raising of invoices and checking invoices from suppliers.
'There is no hierarchy in this business,' he said, 'I also do most of the quotes working with the setters to establish cycle times - well at least for CNC - I can still do cam machine quotes with my eyes almost shut, a factor of doing it for so long.' Both Citizen C-Series machines installed at Quality Couplings have main and sub spindles with two-gang tool slides enabling simultaneous machining with three tools.
The C32-VIII has an 8,000 rev/min main and 7,000 rev/min sub spindle with 14 tools and eight driven tools powered by 1kW motors.
The C16-VII has 18 tools plus eight driven by 1kW motors.
What has impressed Elliot is the support from NC Engineering.
'We had a couple of problems on a parts-catcher and for some reason a troublesome platen on the C16.
NC Engineering was able to locate and replace the platen the next day,' he said.
'Now that's what I call service,' he maintained.
While Elliot runs the day to day operation of Quality Couplings, his son, John 'junior', runs a submersible and surface pump supply operation from the same premises.
While not involved in his father's production interests, the two do vie for storage space and, with a knowing wink and a definite pride in his son's achievements, Elliot said he enjoys keeping the younger businessman on his toes.
'He's got to make space for my expansion,' maintained Elliot, 'Because I've got the bit between my teeth to adopt new technology and there will be more CNC machines installed soon.

Sliding head automatic lathe deep-hole drills
CNC sliding head automatic lathe has a deep hole drilling facility and a motion control that allows very high speed cutting cycles for relatively simple turning operations.
A defining feature of the new Star SR-20RIII lathe compared with the RII model is its ability to drill a hole down the center of a 20mm diameter bar to a depth of 100mm, using the 3.7kW / 10,000 rev/min main spindle in conjunction with two additional front-facing tools mounted next to the opposed spindle. Another key feature is the Fanuc 300iS CNC with motion control, capable of very high speed cutting cycles for relatively simple turning operations when running programs created and optimised off-line using powerful computer-aided manufacturing software from Star. Conventional ISO programming and computer numerical control is reserved for producing more complex components.
The SR-20RIII will be demonstrated for the first time in the UK at customer launch days to be held at Star Micronics GB's technical centre in Melbourne, Derbyshire, on April 24-26 2007.
Star is also keen to point out that there will be special offers on certain machine models during the three-day event.
In addition, Iscar tooling will feature and Delcam will be making presentations on its Partmaker CAM software.
Managing director, Bob Hunt, is particularly pleased that the Japanese parent company has priced the new 7-axis mill-turn centre at a similar level as the original cost of an SR-20RII, so the additional RIII features are available at almost zero cost.
The specification of the RII has been reconfigured and will be offered alongside the RIII.
Further promoting high productivity are 35m/min rapid feeds in all linear axes, higher than on the RII and equivalent to the fastest machine in Star's range, the SR-10J.
C-axis positioning of the main and sub spindles in 0.01 deg increments is similarly fast at over 9 rev/s.
Despite the RIII's agility, it is a robust machine weighing 2.2 tonnes, capable of achieving very high accuracy and surface finish.
Spindle cooling ensures thermal stability and also contributes to high precision machining.
The working area can accommodate a large number of cutters in addition to the deep hole drills and the usual six ganged turning tools above the guide bush.
They include four front-facing and four rear-facing end-working tools in the main sleeve holder; up to 10 live cross-working stations, some of which may be swapped for more end-working tools or other attachments such as for angle drilling, hobbing or roller burnishing; and an independent, four-spindle back-working unit with live and stationary positions.
The design of a new product is not complete these days without measures to reduce its environmental impact.

Manual/CNC lathe can also perform milling
The latest generation of advanced customised controls and conversational programming systems feature on the first Harrison manual/CNC lathe to have a milling facility.
The new Alpha X Series lathes from British lathe manufacturer T S Harrison, which was premiered at EMO 2005, features the latest generation of advanced customised controls and programming systems developed by Harrison design engineers in partnership with the industry-leading automation technology specialist, GE Fanuc. The Alpha X Series, comprising the XT, XS and top-of-the-range, 3-axis XM - the first Harrison lathe produced with milling capability - takes the Harrison range into a new era of performance, with significant enhancements in the crucial parameters of turning speeds, power and reliability. All new Alpha X Series lathes incorporate Fanuc's latest conversational programming software facility and offer the fastest, easiest set-up of any lathes in the market.
* Controls and control features - the 'entry-level' Alpha XT models (comprising the 1350XT, 1400XT, 1460XT and 1550XT) are all equipped with the GE Fanuc Oi Mate TC control.
This is loaded with the new Fanuc Turn Mate i conversational system.
The new controls for Harrison Alpha XT lathes feature: * 7.2in LCD mono operator touchscreens.
* ISO standard CNC.
* Full Fanuc CNC keyboards.
* One-click-one-micron feel handwheels.
* Sliding operator console for maximum convenience during loading and set-up.
* Rapid traverse joystick.
The Turn Mate i system on the XT models enables up to 40 separate operations to be stored in the software, allowing multiple options for profiling, grooving, facing, threading, drilling and tapping, radii and chamfers, boring, tapering and simple stops.
For the first time on the Alpha T range of machines it allows full contour programming at the control.
Another 'first' for the Alpha XT range, compared with the previous Alpha T models, is the ability to switch the control to full ISO functionality (CNC).
This empowers more experienced operators to run programmes previously used on other machines and/or to generate programs in the CNC format.
This is also the first time that any Alpha T model has been available with an eight-station bi-directional turret which increases its automation capability.
As with all previous Alpha machines, Harrison's Alphalink CAD/CAM software is supplied to customers free of charge.
The Windows-compatible system allows simple generation of standard ISO (CNC) programs and the use of previously-generated DXF files.
David Smith, Harrison's sales director, explained that the customized control system for the Alpha XT models has been extensively developed to provide a 'total system solution' for optimum integration of all key systems: servos, spindle, drives, control, operator panel and electrical components.
'Like all versions of the X Series, the Alpha XT lathes are perfectly suited to producing 'one-offs' and small-batch turned parts.
No other lathes on the market today, including full CNC machines, can compete with the X Series for speed of production when it comes to these small volume turning applications,' he said.
The new Harrison Alpha XS line-up (comprising the 1350XS, 1400XS, 1460XS, 1550XS, and 1800XS), was similarly developed between Harrison and GE Fanuc.
The Alpha XS lathes have the GE Fanuc 21i TB control, loaded with custom-written Alpha mode programming software, which is unique to Harrison Alpha lathes, and the Fanuc Manual Guide i conversational programming system.
The key specifications are: * Ultra high-speed GE Fanuc 21i TB CNC control.
* 10.4in colour operator touchscreen.
* Two software systems (Alpha system + GE Fanuc Manual Guide i).
* Industry standard ISO programming.
* High-speed fibre optic data transfer.
* PCMCIA (flash card) and RS232 communication ports.
* Twin MPG handwheels.
* Rapid traverse joystick.
'The Alpha system software is well-recognised as the easiest control in the world to both learn and operate by a manual-lathe trained operator.
Its functions start with electronic stops, which directly mimic the familiar manual stops, and progress to automatic machining of complex forms.
At no time does the operator require any knowledge of CNC programming,' explained Smith.
'Manual Guide i is an easy-to-use, intuitive programming system designed to assist the less experienced operator to gain full advantage of the features of even the most complex of machining functions.
It is important to note this has been customised by Harrison to make the Manual Guide i fitted to these XS machines absolutely unique to the Alpha products and faster to programme than any other similar lathe.' The customised control system fitted to all Alpha XS lathes are designed to allow operators to utilize the machines to their full potential and capability with minimal training.
The Manual Guide i system offers a full range of easy, conversational cycles for direct 'at the machine' component set up.
Following programming the cycles may be simulated using 3D solid model graphics.
The new Alpha 1550XM lathe is identical in operation to the XS range, but has the additional functionality of a C axis and driven tool capability.
These machines utilise a standard headstock and newly-developed servo-driven worm and wheel drive.
Engagement of the drive to establish C-axis control is achieved via an electrically-driven actuator.
The tool-mounting options offered with the Alpha 1550XM are a Duplomatic 8-station turret (4 driven tool positions) or a Sandvik Capto driven tool-post allowing manual change of standard, Capto or driven tool holders.
To utilise the total C-axis capabilities of the machine, comprehensive C-axis programming cycles are available through both the Manual Guide i conversational system and the enhanced version of AlphaLink CAD/CAM software.
This total C-axis functionality allows milling, PCD (pitch-circle-diameter) and radial drilling, tapping, keyways, cam profiles etc to be generated off-line.

Manual/CNC lathe expands turning capacity
Subcontract machinist said his customers knew he had acquired a manual/CNC (combination) lathe because he could make several parts in the time needed previously to machine one.
Chris Evans has been running Buckwood Engineering on his own for the past 20 years, and that is just the way he likes it. 'After 15 years in the family business, which employed 350 people, I decided I could do without the aggravation and set up on my own. I like being hands-on and will machine anything that comes my way.
I am never going to be a millionaire but I enjoy what I do.' Half of Buckwood Engineering's 1000ft2 premises at Markyate, Hertfordshire, is leased to another one-man engineering business, while the remainder is home to manual machines and, more recently, two manual/CNC machines supplied by Burlescombe, Devon-based XYZ Machine Tools.
Evans said: 'I bought an XYZ Edge 1500 manual/CNC turret mill as a replacement for an old manual turret mill and thought it would be my last machine tool purchase.
It proved to be an unbelievably good machine and I found myself taking a third of the time to complete a job, even though I had no previous CNC experience.
I did not even go for training because it is so easy to use.' Despite this success Evans continued to rely on a manual lathe until he realised that he was losing out on turning work from existing customers and decided to do something about the situation.
One month later, in January 2005, he took delivery of a new XYZ ProTURN VL 355 lathe equipped with ProtoTRAK CNC.
'My customers know I have the ProTURN because I can now make several parts in the time needed previously to machine one.
This allows me to quote lower prices while still earning enough to pay for the machine and to put money in my pocket.' According to Evans, he opted for the 5.75kW, 360mm swing over bed XYZ ProTURN VL 355 because it matched the capacity of his DRO-equipped manual lathe while offering a choice of manual machining or, courtesy of the ProtoTRAK VL control, partial or full CNC control.
This flexibility is ideal for a small business like Buckwood Engineering that is called upon to machine a wide range of work pieces in varying batch sizes.
'There is not a turning job I can not do on the ProTURN because it is so simple to program, usually taking two to three minutes, and the program can be stored and recalled if I get a repeat order.
Although a one-off takes around a quarter of the time needed on a manual machine, a production batch probably takes 10 to 20% of the time, with a guarantee that every part will be identical.
I have just completed a 120-off job in a cycle time per part of six minutes compared with about an hour on the manual lathe, and within those six minutes I completed a second operation milling and drilling cycle on the ProtoTRAK mill.' Although adamant that the ProTURN lathe, definitely, is his final machine tool purchase, Evans says the move to CNC has made a very real difference to his life.
'I can now go home earlier that before, which allows me to indulge in my passion for chess, and I take regular holidays.

Toolroom CNC lathe is powerful, flexible, simple
Toolroom Lathe has a proprietary conversational operating system that makes cutting parts and creating part programs nearly effortless, and operation ranges from manual to CNC.
With a functional range from manual turning to full CNC, the Haas TL-1 Toolroom Lathe features a proprietary conversational operating system that makes cutting parts and creating part programs nearly effortless. The operator chooses an operation, touches off the X and Z surfaces, and is then prompted to enter basic dimension information. Default values for feed per revolution, spindle speed and depth of cut are automatically entered by the control, but may be changed by the operator.
Once all necessary information is entered, a push of the Cycle Start button performs the desired operation.
A Recorder function allows information to be saved for future retrieval.
The TL-1 operates in four modes.
In all modes, the Haas control provides extremely accurate digital read-out (DRO) of position, displayed to 0.0005in when using the manual handwheels or to 0.0001in when using the electronic jog handle.
Electronic soft stops may be set to limit the travel of the lathe.
In manual mode, the X and Z axes are moved via standard handwheels.
In semi-automatic mode, the TL-1 performs simultaneous linear interpolation for both axes using a single handwheel.
ID/OD chamfers and tapers, for example, are easily cut in semi-automatic mode.
In automatic mode, built-in machining cycles (both single- and multi-pass) are available for rough and finish profiling, chamfering, grooving, parting off, threading, drilling and tapping.
In full CNC, the TL-1 is programmed using standard G code, and all axis motion is regulated by the Haas control via a G-code program.
Operations that would be difficult or impossible on a manual machine, such as radii, tapers, profiles, grooving, ID and OD threading, and rigid tapping, are all possible on the TL-1 - without knowledge of G-code programming.
Help menus are available directly on-screen, and a dry-run graphics feature allows operators to check their work before running a part.
MACH 2006 witnessed several new machines from Haas Automation, the largest CNC machine tool manufacturer in the world.
Haas demonstrated machines and metal cutting technology for aerospace, automotive, medical, mould and die and general machining industries.
More than 25 CNC technology products were on show demonstrate vertical and horizontal machining and turning applications.

Sourced from China, prices start at GBP 4950 for the eMILL 2000 and the smallest of the three models of eTURN.
Despite their ultra low price tags, these machines are of solid ribbed cast iron construction and are fitted with European-sourced bearings and electrical components.
All have full CE approval and are backed by a UK company that has become synonymous with quality, reliability and value for money.
Standard on the 3HP eMILL 2000 is a dual speed range 60-4200 rev/min spindle, power feed to the 1270mm by 254mm table and two-axis digital readout.
Options include a 5000 rev/min inverter driven spindle, power feed to the cross slide and 3- or 4-axis digital readout.
The three models in the eTURN range - 1430, 2060 and 2680 - offer spindle speed ranges from 45-1800 rev/min to 26-2000 rev/min, a swing over the bed from 356mm to 660mm and a between centres distance from 750mm to 2000mm.
Precision CNC toolroom lathe works manually too
A compact precision toolroom lathe has full CNC, but can also be operated manually - the machine's distance between centers is 18in, cross-slide travel is 8in and spindle speed is 0-3000 rev/min.
As technology advances toward miniaturization, machines and machine components get smaller and more efficient. Many shops are purchasing smaller-size lathes to produce these parts. Haas Automation's new compact HHLV-1 precision toolroom lathe is a perfect choice for producing high-quality small- to medium-sized parts without the expense of purchasing a larger machine.
The new HHLV-1 is a hybrid precision toolroom lathe that has a full CNC control, but can also be operated manually.
The distance between centers is 18in, and the cross-slide travel is 8in.
The machine has a part swing of 14in over the guide rail, with 6in over the cross slide.
For versatility, spindle speeds are infinitely variable from 0-3,000 rev/min, and the 5C collet nose accepts a variety of workholding options.
The HHLV-1 has a compact 77' x 32.5in footprint that occupies very little floor space, and the machine is slim enough to fit through a standard 36in doorway.
Haas Automation designed the HHLV-1 to be easy to use and efficient.
A No 3 Morse-taper tailstock and 10-gallon coolant tank are standard equipment.
The heavy steel base includes a utility cabinet with a built-in tooling rack, utility shelf and plenty of room for storage.
The cabinet also allows easy access to the coolant tank.
Options for the HHLV-1 include 4in and 5in 3-jaw chucks, a cam-lock tool post for 1/2in tooling, a steady rest and an 8-station automatic tool turret.
The famous Haas CNC control makes the HHLV-1 easy to program and operate, even for beginners.
Its bright, color LCD display and thoughtful keyboard layout make it a pleasure to use.
The machine comes standard with the Haas Intuitive Programming System, a conversational operating system that guides the operator through basic CNC operations - from initial set up to pressing the Cycle Start button.
You don't have to know G-code to cut make parts, and that makes it one of the most user-friendly CNC controls in the industry.
In manual mode, the standard handwheels and precise digital readout ensure high accuracy and ease of operation.
Manual machinists will be making parts almost immediately.
The tough HHLV-1 is a small, high-precision CNC lathe that incorporates the design philosophy and high quality that make Haas the largest machine-tool manufacturer in North America.
And because it's built in the USA by Haas, it's backed by the worldwide Haas Factory Outlet network of support and service.

Manual/CNC lathe has large 104mm spindle bore
A manual/CNC lathe has a large 104mm spindle bore, which combined with a 560mm swing over bed and a choice of 1000mm, 1750mm or 3000mm between centres, gives maximum flexibility.
The vital statistic of the new XYZ ProTURN SLX 555 manual/CNC lathe is its large 104mm spindle bore. This, combined with a 560 mm swing over bed and a choice of 1000mm, 1750mm or 3000mm between centres, guarantees maximum flexibility, whether machining one-off components or in small batch production mode. However, it is not just the physical dimensions and structural integrity of the ProTURN SLX 555 that prompts XYZ Machine Tools to describe its new lathe as ideal for such applications.
With just a few hours training even someone with little or no CNC experience will be confident of producing complex parts, because the unique 'traking' feature of the ProtoTRAK SLX control ensures that the operator is always in control.
This feature allows the operator to physically wind the hand wheel and so to move the machine through the program at a speed proportional to the speed at which the hand wheel is moving.
Stop or reverse the hand wheel and the machine will do the same.
This allows the operator to check the programmed toolpath before switching to computer control, thereby avoiding collisions and boosting operator confidence.
Standard machine equipment includes a 300mm diameter three-jaw chuck, Dickson quick change toolpost with six holders, air-assist 'floating' tailstock, interlocked chuck and swarf guards, and joystick control for rapid movement.
The ProtoTRAK SLX control contributes constant surface speed, tool tip radius compensation and a host of other features.

Operations software boosts manual/CNC lathe usage
British lathe specialist T S Harrison has significantly enhanced its successful Alpha XT Manual/CNC lathe range with the introduction of 'Operations Link' software, which now offers operators further important advantages in time-saving, automatic linking of operating cycles and workshop efficiency. Technical designers at Harrison, part of the internationally-renowned 600 Group machine tools company based at Heckmondwike, West Yorkshire, have worked closely with the market-leading control systems provider, G E Fanuc, to develop this new software. 'Operations Link' will be incorporated on all newly-supplied Alpha XT machines.
It is also being offered to existing Harrison XT customers free of charge as an easily-installed update.
The four-version Alpha XT range (XT 1350, XT 1400, XT 1460 and XT 1550), is equipped with Fanuc's latest Oi TC Mate control which enables no fewer than 40 advanced, individual machining cycles to be programmed and stored, using the system's Fanuc TurnMate i conversational shop floor programming.
Now, thanks to the launch of 'Operations Link' these cycles can be linked together to create a fully-automatic and continuous machining sequence from start to end, without the need for the lathe operator to tend the machine or switch between cycles.
Philip Stockdale, technical support engineer at T S Harrison, said: 'The early versions of the Alpha XT required the operator to complete each operation and then move from one cycle to the next.
For example you might want to create cycles for a facing operation, followed by a rough and finish turning cycle, and then a threading cycle.' He said: 'Fanuc and Harrison engineers have created the ability to link together these separate operations to produce a complete program, which operates the whole sequence completely automatically with just one press of a button which makes it more like a CNC machine.' The second major benefit of 'Operations Link' is that multi-cycle programs can be transferred via a memory card and stored on a PC for future use - or, crucially, for off-line programming/simulation of complex parts and safety-checking prior to machining.
Furthermore, up to five of these complete programs can be stored on the Alpha XT's Oi Mate control itself, for maximum operating flexibility.
Stockdale explained: 'For small to medium numbers of turned components, the new software speeds up the all-important 'floor-to-floor' time, especially when the Alpha XT lathes are used with the multi-station tool turret.
For these types of turning operations, the quicker and easier it is to complete the machining, the better and more cost-effective it becomes for the toolroom.' He added: 'There are also important benefits in programming time, because large numbers of complete turning programs can be stored.
Operators can create a directory of complete programs on their PCs, which can be downloaded onto the lathe again and again.' As well as Fanuc TurnMate i conversational programming, the advanced Alpha XT lathe range features the ability to switch to full ISO (CNC) functionality.
All Alpha XT customers also receive Harrison's 'Alphalink' CAD/CAM software which is a fully Windows-compatible system for flexible off-line programming.

Turning can be manual, electronic or CNC
Combination' or 'half-NC' lathes combine conventional turning, electronic cycle turning and full CNC turning in one machine and the user needs no CNC training to use electronic turning cycles.
Centre lathe turning has progressed at an impressive rate since the conception of electronics, driving axis and spindles, and computer driven programming. The Ajax Evolution range of machines, combines all the virtues of conventional turning, electronic cycle turning and full CNC turning all in one machine. The Ajax Evolution machines can be used as a manual lathe by using the electronic handwheels and axis joy stick, the control is used as a simple DRO measuring system.
For the 'one-offs' and small batch production the Ajax Evolution can be programmed, using the flexible electronic turning cycles, its quick, its convenient and you do not have to be CNC trained to use the electronic cycles.
You can produce tapers, radii, grooving, multi point profiles and screwcutting by answering simple questions direct from the Fanuc screen.
These electronic cycles can then be linked together to give a complete electronic programme.
For complicated shapes and batch production, full ISO programming on the Fanuc Oi Turn Mate control is possible.
The Ajax Evolution machines include fully enclosed guarding, meeting CE regulations, automatic four-way indexing toolpost, automatic speed range change and new Fanuc touch screen control and monitor on sliding pendant.
Machine programs can be up and downloaded through the RS232 port or saved directly to the PMCIA card.
The range starts at 165mm centre height to 325mm centre height, with bed lengths varying from 750mm to 5000mm, spindle speeds vary for sizes of machines but all have CSS fitted as standard.
Axis and spindle drives are all Fanuc to give reliability and longevity of service.
