SNGA CBN Brazing indexable Insert High speed Machining Cast iron Brake Drum from Halnn Tools
1. Halnn Tools CBN indexable Insert High speed MachiningCast iron Brake Disc
Brake disc, as the most important parts in brake system, were required high on the
surface quality and the Morphological tolerance. And with the development of the society, if the manufacturers want to have benefit, they can only find some methods to improve the efficiency. The first to think for them is change cutting tools.
2. Why we Choose Halnn Tools CBN indexable Insert High speed Machining ?
Halnn researched 4 type CBN inserts grades specific for machining brake disc which can meet their requirements on the process and the surface roughness. The following will share you 4 kinds of CBN inserts.
(1) For roughing process: BN-S300 will be your right choice, the advantages: large cutting depth,
good wear resistance and long tool life.
(2) For finishing process:BNK30, BN-K20and BN-K10 can be the right choice, BNK30 can be made of both brazing and solid type, it has sharp cutting edges, high precision and long tool life. BN-K20 belong to brazing CBN insert, it has multi-cutting edges, will be more economic.BN-K10 belong to PCBN insert.
3. CBN indexable Insert Characteristics
