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.
