Abstract:
1. A method for manufacturing a surface-coated cutting insert, comprising: forming at least one coating layer on a cutting insert, the cutting insert including a pair of parallel polygonal faces and a plurality of lateral faces; clamping and holding the surface-coated cutting insert with a pair of 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 the surface of the surface-coated cutting insert using at least one blasting gun while rotating the surface-coated cutting insert, 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 pressure of the abrasive fluid from the blasting gun is controlled in one or a plurality of regions of rotation while the rotary shafts make one revolution around the axis.
