Turning high speed steel rolls with BN-S20 solid CBN inserts

High speed steel rolls are difficult to process mill roll for machinery factory due to the high hardness of the casting roll and surface casting defects (hard spot, sand, porosity and so on). Therefore, it is important to choose suit insert material in process, CBN insert is the preferred material in machining metallic material field at present, especially Halnn superhard researched BN-S20 cbn inserts, which is solid cbn inserts, and used widely in high speed steel roll industry.

The advantages of machining high speed steel rolls with BN-S20 soid cbn inserts

(1)   The hardness range of Halnn BN-S20 CBN insert at HRC95-100, high hardness and good abrasion resistance,

(2)   Using non-metallic ceramic as a binder,

(3)   Achieve large margin, high metal cutting rate,

(4)   Dry cutting, reduce environmental pollution, the chip is easily recycled.

Application industry

Engineering machinery, transportation industry, mining machinery, metallurgical machinery, energy sector, such as high speed steel rolls, forged steel cold roll, large gears, high manganese steel, rolling hard steel, heat-resistant alloys, thermal spraying and other hard surface spray processing field.

Suited Materials

BN-S20 mainly used for Quenched steel ,high strength steel ,Rolled steel,heat-resistant and wear-resistant steel ,Nickel-based alloys and other Hard-facing material.
