Lapping / Sanding

 

It is carried out by rotating an expansion head with abrasive stones, combined with a special oil, which remove the material.

The workpiece remains stationary and the head slides back and forth thank to a shaft fixed to a motorized carriage.

Surface finishes with very low roughness (Ra 0,2/0,1) obtained with various passes of abrasive paper with increasingly fine grain can be achived.
