Product Description

1.  Halnn Tools BN-S200  CBN Cutting Tool full form High speed Machining Hardened Steel Bearing

As one of the main components of the wind energy industry, the slewing bearing is often used in the heat treatment process to obtain a high service life due to its harsh working environment and expensive maintenance and time-consuming, so as to ensure a high service life of the slewing bearing.

The surface of the slewing bearing is quenched to a hardness of HRC 55-62, and the hardened layer is generally 3-5 mm. The conventional process uses a grinding process, but it is easy to cause surface burns or cracks. The machining industry has been looking for tool materials that can efficiently machine slewing bearings.

 

2.Advantages of Halnn Tools  CBN Cutting Tool full form High speed Machining Hardened Steel Bearing

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 integral cubic boron nitride 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 quickly, saving processing time and improving processing efficiency.
