Halnn Tools BNK30 / BN-K20 Brazing CBN Cutters Semi-Finishing Cast Iron Brake Drum​

1. Halnn Tools CBN Cutters Semi-Finishing Cast Iron Brake Drum​

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 Cutters Semi-Finishing Cast Iron Brake Drum​ ?

For machining brake disc, the cutting tools materials include carbide alloy insert, coating carbide insert and CBN insert in the market. And only CBN insert can realize high cutting speed, and the performance advantages are higher than carbide insert and coating carbide insert, is the right tools for high speed cutting brake disc.

1)High Hardness, Good wear resistance, which will be about 15-20 times of carbide insert.

2)It can obey high cutting speed, the linear speed can reach 1500m/min, which improved the efficiency.

3)CBN Insert use dry cutting methods, no need to add cutting fluid, the chips can be Recycling easily. It reduces the pollution and lowers the tools costs.

4)CBN insert can help CNC lathe realize high speed cutting brake disc.
