The basic concept of the S12 has been uncompromisingly tailored to precision. At the heart of the machine is a brand new drive/guide system based on linear motors with high-precision positioning (patent pending). The extremely rigid guide tables, supported on hydrostatic bearings, are magnetically prestressed. The infeed movement can be programmed in 10-nanometer steps.

Precision: Infeed movements in 10-nanometer steps thanks to hydrostatic guides and linear motor technology.

Dynamics: Infeed speed 30 m/s, axis accelerations up to 3 m/s

Flexibility: Different dressing concepts, internal grinding spindle on separate cross slide, automatic part handling.
