High quality BNK30 Grade CBN  inserts 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 PCBN Insert ?

At present, the tool materials for machining brake discs on the international market are cemented carbide tools, coated carbide tools and CBN tools, but the comprehensive comparison of CBN tools is the best choice.Please

   1)BNK30 grades have high hardness and good wear resistance, which is 15 times to 20 times that of cemented carbide tools.

   2)Can withstand high-speed cutting, the highest line speed can reach 2000m / min, improve production efficiency

   3)The CBN tool adopts the method of dry cutting， which is more in line with “green manufacturing”.
