Pcd Disc Cbn Tip Cutting Tools Blanks

PCD disc CBN tip cutting tools blanks diamond tool segment
PCBN is made by high pressure high temperature sintering of cubic boron nitride with a binder phase, and there are mainly tow groups of binders, namely metal binder and ceramic binder. CBN and diamond are very similar in crystal structure,chemical bond and lattice parameters,thus they perform quite similar hardness and strength. In cutting applications, thewear resistance of PCBN exceeds 50 times that of tungsten carbide.

PCD
PCD(Polycrystalline Diamond)is a synthesized, extremely tough, intergroup mass of randomly orientated diamond particles in a metal matrix. It is produced by sintering together selected diamond particles at high pressure and temperature.

1. The introduction of PCD cutting tool blanks(PCD cutter/ PCD blanks) :
PCD cutting tool blanks are composed of diamond powder and tungsten carbide in high temperature and pressure. They have the high hardness and abrasion resistance of nature diamond, and combined with the toughness that of tungsten carbide

2.The Application of PCD cutting tool blanks(PCD cutter/ PCD blanks):
Suitable for the machining of non-ferrous metal and alloys, such as aluminum, copper, zinc, as well as wood, ceramics, rubber, plastic, fibre, etc.

3. Some useful tips of PCD cutting tool blanks(PCD cutter/ PCD blanks):
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 its better to be welded with silver solder in a very short time, otherwise will cause carbonizing reaction or crack.
