At present, Halnn CBN tools are  suitable insert for the CNC lathe process brake disc. The reason is as follows:

1. The high hardness and good wear resistance of CBN Inserts is carbide cutting cutter 15-20 times.

2. The CBN Inserts can withstand high-speed cutting, and the maximum line speed can reach 1000 m/min,

3. It can be used for roughing and finishing the work piece with one CBN insert, which will have both high working efficiency and low production costs.

4. CBN Inserts use dry cutting method, without adding the cutting fluid, it is easy to recover the chip processing and obey the concept of "green manufacturing".

5. CBN inserts can help CNC lathe process efficiently the brake discs.

Halnn superhard, as the professional cutting tools leader of processing hard materials, has good cbn inserts grade for roughing and finishing the gray cast iron parts, such as typical parts brake discs.

When roughing the brake disc, the process margin is greater than 1mm, we recommend choose Halnn superhard CBN Inserts BN-S30, which is solid cbn insert, can be processed to complete the margin, and ensure the accuracy requirement.

When finishing the brake discs, we recommend choose Halnn superhard PCBN inserts BN-K20, this grade belongs to the embedded CBN tool, which can guarantee the high finish and flatness.
