BN - S300 TNMN110304 TNMN Solid CBN Turning Insert Finishing Gray Cast iron Brake Disc
1. Halnn Tools TNMN Solid CBN Turning Insert Finishing Gray Cast iron Brake Disc
CBN/PCD inserts are the best choice for high speed and precision machining of high hard material, difficult to cut material and cast irons. They can be used for machining abrasive resistance alloy cast iron like brake disc and brake drum; Or machining normal gray cast iron with high speed, like engine cylinder and cover; Or machining alloy cast iron and alloy cast steel, like roller, slurry pump; Or used for machining some tough material such as hardened steel, bearing steel and die steel; They also can be used for machining high temperature alloy like aeroengine.
2. Why we Choose Halnn ToolsTNMN Solid CBN Turning Insert Finishing Gray Cast iron Brake Disc
With the development of the cutting tools industry, the appearance of superhard cutting tools made it possible that dry cutting and high speed cutting brake disc. Especially HalnnBN-S300, BN-K20 BNK30 and BN-K10 inserts satisfy the customers. And now already used for machining brake disc in this industry.
Above 4 type CBN inserts(BN-S300, BN-K20 BNK30 and BN-K10) all can be normal used with high cutting temperature (about 1300℃), it has high red hardness and chemical stability. And the cutting speed can reach 1500m/min when finish turning brake disc. And the surface roughness can be ensure within Ra1.6.
