1. Why choose Halnn BN-S300?

Halnn super hard cubic boron nitride tool BN-S300 grade belongs to the whole polycrystalline cubic boron nitride tool with coarse and fine processing. The line speed reaches 200-700m/min, the depth of the knife is 1-10mm, the feed rate 0.2-1 mm/r. Finished gray cast iron selection of Halnn super hard cubic boron nitride tool BN-K20 grade, line speed of 300-1500m / min, the depth of the knife is less than 0.3mm, the feed rate is 0.05-0.3mm / r. The cutting parameters are adjusted according to the rigidity of the machine tool. The rigidity of the machine tool is high, the high feed rate is high, and the large knife is processed deep, and vice versa.

2. Advantage.

(1) BN-S300 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”.
