With 3 CNC axes as standard, the X axis (linear motor drive) ensures a high relief turning frequency. OnBoard profile calculation, 21” multi-touch panel and workpiece-specific HMI allow for short setup times.
Option: linear relief turning, etc.

Technical Data:

Workpiece diameter max.* 220 mm
Turning length 630 mm
Module 0,5 - 8
Relief turning frequency 15 Hz

*(other models available)


Retrofitting or modernising an existing machine is often a better alternative to investing in a new machine. This kind of modernisation allows you to make use of any base machine elements that are still in good condition (e.g. machine bed, various cast parts). Here, change-speed gears etc. are replaced with CNC drives, any existing dressing technology is usually replaced with flexible CNC dressing.

Modernisation is completed with a high-performance CNC control system with user-friendly dialogue programming and the option for state-of-the-art remote diagnostics.

These machines can also be equipped with an automatic loading system and/or specific profiling software and much more.

This could possibly be a more cost-effective alternative to a new machine.
