Product Description

1.  Halnn Tools BN-S20  full form CBN Cutters High speed Machining 50Mn Bearing steel Wind Power Bearings

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 CBN Cutters High speed Machining 50Mn Bearing steel Wind Power Bearings

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.
