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

With the continuous development and innovation of the tool industry, the company has finally developed a high-efficiency cutting tool and realized the “replacement grinding by turning” process. The “turning for grinding instead of grinding” process not only avoids grinding burns, but also mainly performs dry cutting, achieving clean production and creating a good processing environment.

Tool materials that can be used to “turn and grind instead of grinding” slewing bearings are coated, ceramic and CBN. In order to reduce the production cost, different parts need to choose different tool materials. For example, the slewing bearing with larger diameter gears is better to choose more wear-resistant ceramic tools and CBN tools.

Secondly, ceramic tools and CBN tools can be used in combination, among which ceramic tools are brittle. CBN tool hardness is second only to diamond. It is called superhard tool and can process ferrous metal above HRC45, especially in the field of hardened steel.

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.

5.Application Case

When machining large scale bearings and high precision bearings, hard turning (turning instead of grinding) is a trend, the process efficiency is high and the cost is low. Traditional cutting tools carbide insert and ceramic cutters can’t satisfy their requirements.

Hard turning the wind power bearings outer ring and inner circle. Because of the large diameters of the wind power bearings, the allowance after heat treatment will be large, specific for this phenomenon, Halnn recommend solid cbn insert BN-S20 and BN-S200, the tool life will improve several times than ceramic cutters, and can obtain good surface quality.
