PCBN Inserts High Speed Machining Brake Drum with High Heat Resistance

1. Halnn Tools PCBN Inserts High Speed Machining Brake Rotor

The excellent performance of CBN tools: High hardness, high heat resistance, high chemical inertness.

The high hardness of CBN Tool proved its excellent abrasive resistance.

● The high heat resistance of CBN Tool can meet the cutting condition of high speed and high temperature.

● The high chemical inertness proved that CBN Tool has high antioxidant, it will not be oxidized in 1000℃,and will not react with iron series metal in 1200 ℃. And it can be used with high cutting speed, so that improved the processing efficiency.

● CBN Tools have good thermal conductivity, which can realize the heat near the insert tips, and help improve the precision of the workpiece.

● CBN Tools will have low coefficient of friction, which will make the cutting tools have excellent anti-sticking ability, and help improve the surface quality of the component.

2. Why we Choose Halnn Tools PCBN Inserts High Speed Machining Brake Rotor ?

Specific brake disc parts, Halnn launched BN-S300,BN-K20 ,BNK30and BN-K10 4 grades CBN inserts, their advantages are as follows:

(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 reduce the pollution and lower the tools costs.
