Drives

Electromechanical drive of the Y- and Z-axis and rotary table

Measuring system

Precise positioning using a direct measuring system on the Y-axis (Heidenhain) and a rotary encoder on the Z-axis

Spindle technology

Grinding spindle separated from motor via coupling, eliminating heat transfer
Continuously adjustable grinding spindle motor with constant cutting speed up to 35 m/s (optionally up to 50 m/s) over the entire range of use of the grinding wheel (vconstant)
Long service life due to a grinding spindle supported by 6 rolling bearings, grease-lubricated for life

Magnetic clamping technology

Heat-free electro-permanent magnetic chuck
Integrated pole-reversal control unit with 16 different clamping forces

Coolant system

Maintenance-free belt filter system with integrated channel flushing incl. cleaning gun with hose and magnetic separator for pre-filtration
