The performance is different. baiCBN mainly processes black high-hardness metals such as hardened steel and cast steel (iron). Dao can withstand high temperatures (over 1000 degrees shu), and the hardness is always 8000HV, which is a better way to improve production efficiency and process difficult-to-process materials. Good tool material.
PCD is mainly used for processing non-ferrous metals such as non-ferrous metals. It can sharpen sharp edges and obtain a better processed surface, which can generally achieve a finish of 0.2.
The main processing objects of CBN tools are cast iron and quenched steel. The application industry is also mainly in the automotive engine and bearing industry.
Compared with PCD tools, CBN tools are easier to process. Moreover, with the promotion of energy saving in the automotive industry, more and more cars use aluminum alloy substrates in automotive engines. Therefore, CBN is invaded by PCD blades in automotive engine milling. .
Of course, with the declining cost of CBN cutting tools, in the field of automotive brake discs, CBN turning inserts have also replaced the share of traditional carbide turning inserts. It should be said that with the increasing number of CBN material grades, this traditional hard material turning and grinding field, the share of CBN tools will continue to rise.
