The Machine Frame
The machine frame is a mineral casting, which guarantees excellent thermal stability and improved vibration absorption. This results in a better surface finish on machined parts and longer tool life.
All linear axes have direct measurement scales for position feedback. The system resolution is less than 1 µm.

The Part
The electonic synchronization between the part and the tool guarantees a high-quality finish.
The part is generally held between centers and direct-driven by two independent motor spindles. The cutting tool (hob) is driven by a third motor spindle. The three motor spindles are electronically synchronized with rotation speeds of up to 16'000 rpm.
The infeed axis, which defines the precision of the part’s diameter, has a direct measurement linear scale for position feedback. The system resolution is less than 1 µm.
