High speed Machining Gray Cast iron Brake Disc with TNGA Brazed CBN Tool from Halnn Tools
1. Halnn Tools CBN Tool High Speed Cutting 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.
2. Why we Choose Halnn CBN Tool High Speed Cutting Brake Disc ?
In previous times, the main cutting tools for machining brake disc in China are carbide insert and coating carbide insert, and most of them use common lathe, it affects the processing efficiency seriously. In current times, with the development of the society, they change the common lathe to CNC Lathe, and it can be used with high cutting speed, so it must change the cutting tools materials to meet the lathe’s requirements.
Halnn Tools, as the predecessor of superhard cutting tools industry, already researched superhard cutting tools more than 17 years, and launched 4 grades CBN Tools for specific machining brake disc: BN-S300, BN-K20 BNK30 and BN-K10 CBN Tools. They have obvious advantages for machining brake disc than traditional carbide Tools.
