Abstract

A metal-ceramic composition used as the binder of ultra-hard abrasive tool is prepared from metallic binder (5-95 Wt%) and ceramic binder (5-95 Wt%). Its preparing process is also disclosed.

Description

1. Technical field: [0001] The invention relates to a new formula and a production process of a superhard material abrasive tool bond, in particular to a formula and a production process of a metal-ceramic composite material used as a superhard material abrasive tool bond. 2. Background technology: [0002] With the advancement of industrial technology, high-speed, high-efficiency, and high-precision grinding has become the mainstream of today's grinding technology development. As an advanced processing technology, grinding of superhard materials has continuously expanded its application fields. The processing of difficult-to-grind metal materials in the tool industry has been extended to the processing of ordinary ferrous metals such as bearings, automobiles, machine tools, and non-metallic materials such as ceramics, which has a tendency to replace ordinary abrasive tools. [0003] In addition, at present, countries have invested a lot of manpower and funds in the research...
