Bearing Steel(100Cr6,100C6,E52100), as one of the best steels, has been widely used in power industry, metallurgical and wind power industry.
Because of the bad working environment, bearings steel need have the following advantages: High hardness, good impact resistance, toughness, wear resistance and dimension stable performance. We often use heat treatment to improve the bearing steel performance.
In order to obtain good usage performance and improve the hardness of the bearing steel(100Cr6), the manufacturers usually use heat treatment process. However, the insert will wear rapidly, and has low efficiency and the roughness is not good. At that time, choose the right cutting tools become very important.
At first, the manufacturers use grinding process, and it can obtain good dimension and precision. But with the mass production, the grinding process already can’t meet the efficiency requirements. So manufacturers need to search new cutting tools to satisfy their requirements. And with the development of the technology, it appears 3 types cutting tools materials, carbide insert, ceramic cutters and cbn insert.
From hardness, cbn insert>ceramic cutters>carbide insert.
And from the toughness, cbn insert>carbide insert>ceramic cutters.
Even cbn inserts are better than carbide insert and ceramic cutters, but the brittle is large, only can be used for finishing process. And later, Halnn researched non-metal adhesive cbn insert BN-S20 which can be used for large allowance roughing process.
The advantages of Bn-S20 solid cbn inserts as follows:
(1) High hardness and wear resistance, long tool life (10 times of ceramic cutters and carbide insert)
(2) BN-S20 use non-metal adhesive as the binder, improve the impact resistance and realize large allowance turning and interrupt cut.
(3) It can be used for high speed turning bearing steel, and can make sure the excellent size and precision.
(4) Dry cutting process, reduce the environment pollution.
