1. Halnn Tools Solid CBN cutting tools Hard Part Turning Bearing steel Wind turbine bearing races

Wind power bearings are often made of GCr15SiMn main material, and then subjected to the following steps for forging technology.

（1）Roughing: Forging type wind power bearings are processed, and carbide tools are selected for processing. For high hardness (above HRC454), Halnn Tools cubic boron nitride inserts can be selected to achieve a depth of 7.5mm. After that, there is a corresponding machining allowance for the subsequent finishing.

（2）Heat treatment: heat treatment of wind power bearings after roughing to improve the hardness, wear resistance and impact resistance of the workpiece, and obtain a good service life.

（3）Finishing: Finished machining of heat-treated workpieces. With the development of modern technology, surface roughness turning tools with accuracy requirements of Ra0.8 can meet the requirements.

2. Characteristics of Solid CBN Cutting Insert

3.Advantages of Halnn Solid CBN Cutting Insert

At present, the tool materials in the processing market are cemented carbide tools, ceramic tools and cubic boron nitride blades. Wind power bearings are large forgings. It is inevitable that deformation will occur after heat treatment, and the balance will be uneven. Therefore, it is not recommended to use ceramic tools. The cubic boron nitride insert is currently the best tool material for processing hardened steel materials. In particular, the non-metallic binder cubic boron nitride inserts BN-S20 grade and BN-S200 grade developed by Halnn Tools have a good effect on processing wind power bearings.

Halnn Tools non-metallic binders Cubic boron nitride inserts BN-S20 grades and BN-S200 grades are all Solid CBN inserts, of which BN-S200 grades are mainly used for finishing operations, and the depth of the knife is controlled at 0.5mm. Within. The BN-S20 grade can be used for rough finishing. It is mainly used for wind power bearings with a margin of >2mm or more. It can be processed by one knife, saving processing time and improving processing efficiency.
