Introduction to PCD cutting tool materials
Diamond has been used as super-hard cutting tool materials for hundreds of years. In the course of the development
of cutting tools, high speed steel was the major cutting tool materials from the end of the nineteenth century till the mi-

ddle of the 20th century. In 1927, carbide tool material was firstly developed in Germany and later on extensively used in
coming decades. The successful synthesis of diamond in 1950s increased the applications of super-hard cutting tool ma-

2) For ease of tool fabrication, PCD is usually sintered directly to a tungsten carbide backing, which offers higher resistance to shock.

3) PCD can be easily made to large size tool blanks, which meets the demands of large cutting tools like milling tools.
4) Laser cutting, polishing and EDM machining can be accessible for the machining of PCD materials, and special sizes
may be machined.
