CBN tool with high hardness and wear resistance, and diamond tools collectively referred to as super-hard tool, but also with the iron metal affinity, high thermal conductivity, cutting is not easy to produce BUE, to ensure a high surface quality.

After several decades of development of CBN tools, there are three kinds of tool structure, one is the overall polycrystalline CBN tool, one is a composite CBN tool, and the other is a mosaic CBN tool. Different structures, the processing of the area are also different.

The overall polycrystalline CBN tool, the whole body is cubic boron nitride material, mainly used for roughing process, the margin of machining allowance, but also to ensure good surface quality.

Welded CBN tool and inlaid CBN tool, because only the cutting edge is cubic boron nitride material, the base is cemented carbide, so mainly for finishing process, the advantage of high-speed cutting, to ensure that the workpiece surface roughness .

Compared with traditional carbide cutting tools, CBN cutting tools not only have much higher efficiency but also have a longer service life than carbide cutting tools. CBN cutting tools, Reduce processing technology, improve production efficiency.

As a kind of superhard cutting tool, CBN tooling has good prospects in the market. With the increasing number of hard-to-machine materials with high hardness, the application fields of CBN cutting tools are gradually widened. The future of CBN tools will achieve very good development.
