1.  Halnn Tools BN-S20  full form PCBN inserts Interrupt Cutting 42CrMo4 Bearing steel Wind turbine bearing 

As the main components of the wind power industry, wind power bearings have strict process requirements in the manufacturing process. Although grinding can guarantee its high precision, the efficiency is too low, which affects the production schedule. CBN tools are more wear resistant than carbide tools and more resistant to chipping than ceramic tools. They are the best material for processing high hardness steel parts. Among them, the CBN tool manufacturer,has a specific tool material processing for wind power bearings. 

2.Advantages of Halnn Tools full form PCBN inserts Interrupt Cutting 42CrMo4 Bearing steel Wind turbine bearing 

Halnn Tools specializes in CBN tools for cutting hard materials and high-grade PCD, and enjoys a high reputation in the academic field of superhard tools, especially in “replacement grinding by turning”, ultra-high hardness heavy-duty cutting, cast iron high speed. Processing and other advantages are unique at home and abroad.

For the bearing industry, Halnn Tools has developed BN-S20 grades, BN-S200 grades and BN-H11 grades of three CBN cutters for roughing and finishing processes, respectively, to improve production efficiency in addition to high quality bearings. reduce manufacturing cost.

The BN-S20 grade is mainly used for rough machining of bearings. It can cut the machining allowance of the bearing, reduce the number of passes, and can withstand high temperature cutting to ensure long tool life.
