Internal grinding and finishing without re-clamping

Optimized surface quality through a finishing process as final operation achieved in one clamping.

Result :
Absolute perpendicularity between internal guiding diameter and external face.

Geometric forms at face :
flat / convex / concave

Accuracies at face :
Flatness < 1 µm
Surface quality (Rz) 0.3 µm

Self-sharpening finishing tools only have to be conditioned one single time. For longer finsih tool life, Bahmueller uses an additional cup wheel located on the finishing spindle for pre- grinding the face.

Essential for modern high-pressure injection systems!
