Abstract

PURPOSE:To prevent a diamond film from being peeled off and to enable the effect of wear resistance to be stably maintained by covering a base material with diamonds from whose material sharp cutting edges are removed, and eliminating defects of the cutting edge within the thin film of the diamonds. CONSTITUTION:As a preventive measure against possible defects caused by stress concentration, a chamfer honing surface 6 is provided in advance, which has an inclination alpha of 15 to 30 deg. to a rake face 4 and a dimension (a) as well measured from a flank side 5 and is equal to or more than 0.01mm or less than 0.08mm, for the cutting edge section of a base material 1 in such a way that the thin film of diamonds 2 is formed by means of vapor phase elaboration. In this case, a round honing surface may be employed, which has the same dimension (a) measured form the rake face 5 as that of the aforesaid honing surface as the honing treatment of the cutting edge section of the base material. The reason why the dimension (a) is defined is that no significant effect is noticed in case of the dimension (a) less than 0.01mm, on the other hand, cutting resistance is increased accompanied with the welding of chips in case of the dimension equal to or more than 0.08mm.
