Machining Grey Cast Iron Brake Disc with BN - S300 RCMN060400 CBN Tip Rough

Machining Grey Cast Iron Brake Disc with BN - S300 RCMN060400 CBN Tip Rough

1. Halnn Tools CBN Tip Rough Machining Grey Cast Iron Brake Disc​

According to statistics, in the cost of machine manufacturing industry, the cutting fluid has occupied 15%, and the costs on cutting tools only have 3%~5%. So the new technology of dry cutting will become one new technology. It not only can lower the total costs, but also can reduce the environment pollution. In the process, the most important is cutting tool material. In order to achieve high cutting speed and dry cutting type, the cutting tools materials need have High temperature red hardness, stability and low Coefficient of friction. The materials can be only cubic boron nitride in nowadays.

2. Why we Choose Halnn Tools CBN Tip Rough Machining Grey Cast Iron Brake Disc​

Compared with homogenous products: using nano-scale binder and high-grade CBN material ratio, it has more stable cutting performance, and the tool life is 1-2 times that of homogenous products. The welded CBN tool guarantees no U-turn, ensuring stable working conditions in the case of intermittent cutting, and not wearing the cutter.

Compared with the imported brand CBN tool: the cutting performance is stable and the cost performance is higher, especially in the sub-segment of “car grinding” ultra-high hardness heavy-duty cutting, cast iron high-speed machining and so on.
