Unique machine concept
Topology optimization

Topology optimization for a perfect combination between stability, damping and weight.

Motorized spindles

Thanks to the different types of motorized spindles (HSK, CAT, BT, SK, BIG-PLUS) you will have a bride range of possibilities to find the optimal solution for your machining. 

Drive concept

Depending on the equipment, the drive concept is based on one ball screw drive arranged in the mass center or two symmetrically arranged ball screw drives in the Y-axis. The torque motor in the B' axis, which is already installed in the standard model, also enables a fast positioning movement with maximum precision.

Maximum stability

Optimally designed Tool Center Point (TCP) ensures extremely stable processes and high cutting performance.

Efficient machine cooling

Our efficient machine cooling concept includes the cooling of the power train, control cabinet, motorized spindle, rotary table and cutting fluid system, whereby a high level of accuracy is achieved on the part. 

Machine control system

Working with familiar control system with choice between SIEMENS or FANUC machine controls 

Work area

The maximum possible part can be machined in the work area with the maximum tool length (up to 830 mm).

Tool magazine

Choice between different tool magazine types in different sizes (up to 450 pockets). These have a modular structure and can also be exchanged afterwards using “plug and play”.

Chip conveyor

The chip conveyor can be designed for your different machining processes and is suitable for a wide variety of materials.

Cutting fluid system

The cutting fluid system is available in different packages and ensures a chip-free work area and a stable process. The optionally available IKZ with up to 120 bar rounds off the various additional options.
