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.
