High efficiency Hard Turning Hardened Steel Wind turbine bearing with Halnn supplier CNMN120704 CBN Cutters 

1. Halnn Tools CBN Cutters High efficiency Hard Turning Hardened Steel Wind turbine bearing 

When machining large bearings and high-precision bearings, the hard turning process is a processing trend in the bearing industry. Its processing efficiency is high and its cost is low, and traditional processes cannot compete with it. However, the hard turning process requires high cutting tools. It not only needs to have high hardness and wear resistance, but also guarantees the long service life of the tool. It also needs high temperature red hardness and fracture resistance to ensure the surface quality of the workpiece to be processed. .

The application of CBN tool makes the hard turning process a reality, which not only can remove the bearing allowance, improve the production efficiency, but also ensure the high surface finish of the bearing, the cutting performance is more stable, and the cost performance is higher.

2. Characteristics of CBN Cutters

3. Advantages of Halnn CBN Cutters

The hardness of the slewing bearing after heat treatment is generally above HRC45, and the channel portion is generally HRC55-62, so it is difficult to process during processing. Halnn Tools has developed the BN-S200 grade and BN-S20 grades of cubic boron nitride tools. Both materials are made of non-metal (ceramic) as a binder to ensure high hardness and wear resistance. At the same time, the impact toughness is improved, in which the BN-S200 grade belongs to the finishing process, and the BN-S20 grade can be roughing and finishing.
