Abstract
PURPOSE:To improve the cutting edge strength, chipping resistance and cut resistance by making the basic material of a coated tip from a superhard alloy and forming a layer of titanium carbide and aluminium oxide on the surface except the cutting edge part on the flank surface side and rake face side. CONSTITUTION:All the surface of a superhard article having a prescribed tip shape which is made of superhard alloy, thermet, or ceramics is coated with Ti carbide, carbonized nitride, aluminium oxide, etc. by the chemical evaporation method or the physical evaporation method under the normal or decompressed pressure. Then, the ridge line part where the flank and the rake face of the tip form a cutting edge is horning-processed by machining, and then the formation of a coated film on the cutting edge is prevented. The brittle part on the cutting edge part of the tip is removed through machining, and the generation of chipping and cut on the cutting edge during the cutting work can be prevented, and at the same time, the exfoliation of the coated layer on the cutting edge part is avoided, and the service life of the cutting edge can be prolonged.
