Semi-Finishing of Iron Brake Disc / Brake Rotor with CBN turning tool

Semi-Finishing of Iron Brake Disc / Brake Rotor with  CBN turning tool

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.

Why Choose Halnn Tools  CBN Cutting Tool ?

(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.
