Roughing of Gray Brake Disc / Brake Rotor with Full form CBN Inserts

Roughing of Gray Brake Disc / Brake Rotor with Full form CBN Inserts

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.

Why Choose Halnn Tools   PCBN Inserts ?

(1) Improve Efficiency: Compared with coating carbide insert, it can realize high speed machining,and the suitable linear speed will be: 250~450m/min for roughing process, 450~800m/min for finishing process.

(2) Improve Tools Durability: The tool life of Halnn CBN Insert is about 15 times of carbide insert.
(3) Improve Roughness: Halnn BN-K20 and BN-S30 can receive the roughness within Ra1.6, is much better than carbide insert.
(4) Characteristics of Halnn CBN inserts: BN-S30 and BN-S300 adopt non-metal adhesive, improved the thermal conductivity and the strength, not only extend the insert lifetime, but also improve the impact resistance. And BN-S30 can be used for roughing process, BN-S300 can be used for finishing process. BN-K20 and BNK30 belong to brazed pcbn insert, both of them can be used for finishing process.
