Abstract
PURPOSE:To establish chamfer of about 0.05mm. or more accurately without causing drag to the upper or side surface by forming hard wear resistant ceramic stratum on the surface of carbide tip including at least the cutting edge. CONSTITUTION:The cutting edge of the tip constituted from a chamfered part 3, boundary portion of this chamfered part 3 and upper face, portions with roundness 5 at the boundary of chamfered part 3 and the side face. The width (a) of the chamfered part shall be about 0.05-0.20mm. and preferably 0.05-0.10mm.. And on the surface of this carbite tip including at least the cutting edge, covering layer of such as TiC, TiN, Al2O3 or AlON will be prepared. Thus chamfering of about 0.05mm. or more can accurately be preared without causing drags to the upper surface and/or the side surface. This tip has very high resistance against the crack and wear in comparison with the conventional tips for only chamfer or roundness.
