Abstract
A surface treatment method can perform coated surface treatment on a cutting edge R and a rake surface, while maintaining a radius of curvature of the cutting edge R and uniformly surface-treating the rake surface. The surface treatment method includes providing an opening chamfered at corners adjacent to an upper surface of the fixture to the fixture for fixing a coated cutting insert; fixing the coated cutting insert inside the opening in such a manner that a rake surface of the coated cutting insert is disposed lower than upper surfaces of the fixture but higher than a lower edge created on the opening of the fixture by the chamfering; and conducting the surface treatment on a cutting edge R and the rake surface of the coated cutting insert.
