Halnn BNK30 Brazed CBN Turning Inserts Continuous Machining Brake Disc With High Speed.

1. Advantages of BNK30 grade CBN inserts processing brake disc.

(1) BNK30 grades have high hardness and good wear resistance, which is 15 times to 20 times that of cemented carbide tools.

(2) Can withstand high-speed cutting, the highest line speed can reach 2000m / min, improve production efficiency

(3) The CBN tool adopts the method of dry cutting. It does not add cutting fluid, and the chip is easy to be recycled, which is more in line with “green manufacturing”.
