What is the difference between CBN tool and PCD tool?

Different performance. CBN mainly processes black high-hardness metals, such as hardened steel and cast steel (iron), which can resist high temperature (1000 degrees or above) and the hardness is always 8000HV. It is a good tool material for improving production efficiency and processing difficult-to-process materials.

PCD is mainly used for processing nonferrous metals and other nonferrous metals. It can grind a very sharp cutting edge and obtain a better machined surface, which can generally reach a finish of 0.2.

The main processing objects of CBN tools are cast iron and hardened steel. The application industry is also mainly in the automobile engine and bearing industry.

Compared with PCD tools, CBN tools are easier to machine. Moreover, with the promotion of energy saving in the automobile industry, more and more automobiles use aluminum alloy as their engines. Therefore, in the milling process of automobile engines, CBN has always been occupied by PCD tools.

Of course, with the decrease of CBN tool cost, CBN automobile blades have also replaced the share of traditional cemented carbide automobile blades in the field of automobile brake discs. It should be said that with more and more CBN materials, the share of CBN tools in the field of traditional hard material turning and grinding will continue to rise.

PCD tools are polycrystalline diamond tools and PCBN tools are polycrystalline cubic boron nitride tools, both of which are artificial polycrystalline products.

PCD tools are mainly used to process non-ferrous metals and their alloys, composite materials, artificial plates, graphite, carbon fibers, non-metallic materials and other difficult-to-machine materials. PCBN tools are mainly used for ferrous metals, such as iron, steel, cast iron and hardened steel.
