PCD cutting tool blanks consist of PCD layer integrally sintered at ultrahigh pressure and high temperature to a cemented tungsten carbide backing. They have the high hardness and abrasion resistance of nature diamond, and combined with the toughness that of tungsten carbide. Their life are 10 to 100 times of tungsten carbide cutters. The PCD does not react chemically with non-ferrous metal and nonmetal materials, so it’s suitable for machining of non-ferrous metal and alloys, such as aluminum, copper, zinc, as well as wood, ceramics, rubber, plastic, fibre, etc.

The normal shape is round, also could be cut into rectangles, triangles, sectors, etc. as request. The main controlling factor determining PCD grade(the work piece surface finish and the abrasion resistance(tool life) )is the grain size. It is generally accepted that abrasion resistance increases with increased grain size, and the work piece surface finish are increases with the decreasing grain size. The medium grain size PCD blanks are generally used for their ability to strike a balance between good abrasion resistance (tool life) and maintaining good work piece surface finish.

The PCD blank is thermally stable up to 750°C, so it’s better to be welded with silver solder in a very short time, otherwise will cause carbonizing reaction or crack.
