Abstract:
1. A method for removing a portion of a coating layer of a surface-coated cutting insert, the method comprising the steps of: forming at least one coating layer on a cutting insert for mounting to a mounting seat of an insert-removable machine tool; clamping and holding the surface-coated cutting insert with a pair of coaxial rotary shafts which are rotatable around an axis by a rotary drive device; and removing at least a portion of the outermost layer of the at least one coating layer by jetting an abrasive fluid to a surface of the surface-coated cutting insert using at least one blasting gun while rotating the surface-coated cutting insert integrally with the rotary shafts, thereby, conducting wet blasting with respect to a flank face, a rake face or both of a flank face and a rake face, wherein the jetting angle made by the jetting direction of the abrasive fluid from the blasting gun and the axis is adjustably set in accordance with the portion to which wet blasting is applied.
