Product Description
Halnn BN-S200 solid cbn insert hard turning bearings with HRC60
With the different occasion of the bearings, it required different on the tool life, efficiency and roughness, so most bearings use heat treatment to meet some requirements of the bearings’. The hardness after heat treatment will be above HRC45, and the precision will require Ra0.8, or higher.
Because the surface quality and the size precision are finished by the finishing process, hard turning process required higher on the cutting tools, which will affect the efficiency and the product quality directly. For the bearings with high precision, it will be a big challenge for cutting tools.
GCr15(E52100) is one common bearing steel material, the hardness will be above HRC50 after heat treatment, is difficult to machine.
In early times, they use turning instead of grinding process machining bearings, they use carbide insert, and it will wear rapidly, change the insert frequently will affect the production efficiency. With the appearance of the ceramic cutters and pcbn inserts, the manufacturers begin to use them instead of grinding process.
Pcbn insert is the most effective materials for turning instead of grinding. Especially BNS20, BN-S200 ad BN-H11 are widely used for hard turning bearing industry. Specific for different working condition, we will recommend different cbn grade, Bn-S200 and Bn-H11 can be used for continuous turning process, and BN-S20 can be used for any condition (continuous, interrupt turning condition)
The application case for machining bearings with cbn insert
(1) Finish turning slew bearings raceway, end surface, the hardness is about HRC47~55, the allowance is less than 2mm, we can choose Halnn non-metal adhesive BN-S200 solid cbn insert, the cutting parameters as follows: ap≤1mm,Fr=0.05-0.35mm/r,Vc=60-250m/min, machining effect: The tool life will be 7 times of ceramic cutters, and the roughness can be controlled within Ra0.6~1.0mm.
(2) Finish turning the Cylindrical,endsurface, the hardness is HRC47~55, the allowance will be above 2mm, we recommend Halnn BN-S20 solid cbn insert, the cutting data: ap=1mm,Vc=140-180m/min, the processing efficiency: the tool life is longer and the roughness can reach Ra0.4.
(3) Finish turning the cylindrical and the inner bore, the hardness will be about HRC62, we choose Halnn BN-H11 pcbn insert, the cutting data: ap≤1mm,Fr=0.05-0.35mm/r,Vc=60-250m/min, machining effect: the roughness can be controlled within Ra0.8
