VTM Modular System
The VTM modules enable the configuration of the machine into a multi-functional turning-milling machining center for economical combined machining with a rotary table range from 2500 – 8000 mm and workpiece heights up to 5000 mm. All machines are equipped with two columns and one or two RAM work units. All sizes can be delivered with an adjustable cross-rail (W-axis). Additional advantages of this concept are its reliability and availability combined with cost advantages of proven and standardized machine components.

Powerful RAM Concept
The RAM work units of the VTM series offer a range of innovative technologies for robust and accurate high precision machining as well as very flexible options for the different requirements in turning, drilling and milling operations.
- Broad selection of configurations for power, cross section and RAM length
- Spindle drive with 2-stage transmission integrated in the RAM
- CFK shaft minimize drive wear and optimize dynamics
- Electrically braced master-slave rack & pinion drive with high dynamics and positional accuracy in the X-axis for fast drilling and tapping
- Rigid interface with Hirth coupling and energy supply to adapt different interchangeable heads including self recognition
