Process in 4 steps
1. Intake & wear analysis
We assess wear pattern, remaining tooth height, coating and geometry – the basis for optimal material removal.
2. 5-axis CNC regrinding
Face, flank and profile grinding to original geometry using the stored target contour.
3. PVD recoating
In one package: stripping and recoating (e.g. AlCrona, Balinit) for the full tool life of a new tool.
4. Inspection report & shipping
Pitch, runout and profile check, documented inspection report, ready-to-install return delivery.
