BN-S300 solid cbn inserts for processing brake disc

With the vigorous development of the automotive industry, the demand for brake disc products has increased year by year. As a key component of the car brake system, the brake disc is a powerful guarantee for safe driving. Processing efficiency and quality are especially important for the manufacture of brake discs. Halnn Tools has successively launched the new material CBN inserts BN-S300/BNK30/BN-K20/BN-K10, as the replacement tool materials.

Why Choose Halnn Tools BN-S300 PCBN Insert ?

(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. And it also be suitable for the high speed milling with 1500m/min or above. The efficiency will be about 2 times more than cabide insert.

(2) Improve Tools Durability: The tool life of Halnn CBN Insert is about 15 times of carbide insert.

(3) Characteristics of Halnn CBN inserts: BN-S300 adopt non-metal adhesive, improved the thermal conductivity and the strength, not only extand the insert lifetime, but also improve the impact resistance,and BN-S300 can be used for finishing process.
