Abstract

PURPOSE:To promote the cost down and to eliminate the necessity for repolishing by providing a recessed part in the upper surface corner of a polygonal bed metal consisting of cemented carbides or the like and interposing an active metal, having chemical affinity with diamond, between the diamond and a brazing material. CONSTITUTION:A single crystal diamond cutting edge 3 is chemically connected to a recessed part 2 in a polygonal bed metal 1. This connection is performed by any of the active metals Ti, Ta, Nb, Fe, Hf, having chemical affinity with diamond, or by a Cu-Ag system brazing material under the interposition of their alloy. And the inactive atmosphere of vacuum and argon or the like is required for connecting the active metal to the diamond, but work by the Cu-Ag system brazing material can be performed in the air. While it is preferable to provide at Au layer between the active metal and the Cu-Ag system brazing material and to prevent oxidation. By the above described, promoting the cost down, the necessity for labor of repolishing in cutting is eliminated.

[Function] Made of four parts of highly rigid alloy! Although the diamond cutting blade is as small as 1/20ct, it is superior in accuracy, performance, and durability compared to cutting tools with large diamond cutting blades that are fixed to the shank by conventional caulking or powder metallurgy. There was no place to take as a course. In addition, since the price is reduced, sufficient economy can be achieved as a throw away.
