Surface finishing process for surfaces of rotary-symmetric sectors, involving hard turning using at least one tool with cutting edge shaped to suit working surface of workpiece

摘要

The finishing or semi-finishing process is applied to workpieces (1) of hard or hardened material The hard turning is done using at least one tool with a cutting edge having a shape corresponding to the geometry of the surface (2, 4, 5, 7) of the workpiece being finished, and made of a super-hard cutting material. The tool is fed in the direction of the surface of the workpiece being finished/
