High Speed Turning bearings instead of grinding with BN-H11 PCBN Insert from Halnn Superhard Materials
Bearing, as one of the most important parts in many machine industries, is already widely used in so many industries. With the needs of the bearings, it required higher on the performance of the bearing steel, Heat treatment is one of the common process. Traditional cutting tools will have the following problems:
(1) The hardness will be above HRC45 after heat treatment, some will be above HRC60, traditional cutting tools, such as carbide insert, ceramic cutters will be wearable rapidly, and it will affect the production efficiency.
(2) Some working site of the bearings exist interrupt turning condition, such as machining keyway and oil hole on the surface, the cutting tools will be easily chipping when meet interrupt turning condition.
(3) Large scale bearings, such as wind power bearings, the hardness will be high after heat treatment, and has large deformation, and it will have high requirement on the impact resistance and wear resistance of the cutting tools.
The hardness of the bearings after heat treatment will be above HRC45,
and propose big challenge on the wear resistance, heat resistance of the cutting tools. Specific for above problems, Halnn recommend PCBN Insert BN-S20, BN-S200 and BN-H11 PCBN Insert, they are used for roughing, semi-finishing and finishing process, and helped solve these problems on hard turning bearings.
BN-S20 and BN-S200 belong to solid cbn insert, not only can be used for small cutting depth, but also avoid the failure mode, and improve efficiency of the bearings.
BN-H11 PCBN Insert belong to brazing pcbn insert, has more cutting edges, and excellent wear resistance and heat resistance. When BN-H11 PCBN insert finish turning bearings, it not only make sure the size precision, but also achieve roughness Ra0.8
