Different performance
CBN mainly processing black high hardness metal, such as hard and cast steel (iron), can withstand high temperature (more than 1000 degrees), hardness is always 8000HV,
It is a good tool material for improving production efficiency and processing difficult materials.
PCD is mainly used to process non-ferrous metals and other non-ferrous metals. It can grind out very sharp cutting edge and get a good machining surface, which can generally reach 0.2 finish.
The main processing objects of CBN tool are cast iron and hardened steel. The application industry is also mainly in the automotive engine and bearing industry.
CBN tool compared to PCD tool, is easier to process, and, with the promotion of energy saving in the automobile industry, the automobile engine using aluminum alloy matrix car is also more and more,
So CBN in automobile engine milling by PCD blade encroachment a lot. Of course, as the cost of CBN cutting tools falls, in the field of automotive brake discs,
The CBN blade also replaced the carbide blade share. It should be said that with the increasing number of brands of CBN materials, this traditional hard material turning and grinding field,
The share of CBN cutting tools will continue to rise.
PCD tool is polycrystalline diamond tool, PCBN tool is polycrystalline cubic boron nitride tool, are synthetic polycrystalline products.
PCD tool is mainly used in the processing of non-ferrous metals and their alloys, composite materials, artificial plates, graphite and carbon fiber, non-metallic materials and other difficult materials.
PCBN tool is mainly used for black metals such as iron, steel, cast iron, quenched steel and so on
