PRODUCT DETAIL

CBN grooving inserts: thanks to high hardness, high-temperature resistance, chemical inertness, and impact resistance, CBN grooving inserts are the undisputed top choice for machining brake discs. Their long lifespan and stability significantly reduce unit costs, making them particularly suitable for high-volume production. Other materials (such as carbide and ceramics) are unable to replace the advantages of CBN due to rapid wear or material limitations.

In the past, ceramic grooving inserts were often used for machining brake discs. However, due to their inherent limitations, SCBN with a customer-focused approach, has continuously developed and introduced high-performance CBN grooving inserts to replace ceramic inserts. In addition, the use of SCBN grooving inserts for machining brake discs has been successfully demonstrated in the golbal.

All ceramic grooving inserts can be customized by SCBN  to the corresponding CBN grooving inserts.

When machining brake discs, CBN grooving inserts offer significant advantages over ceramic grooving inserts.

1. Longer tool life—reducing tool change time and costs.

2. Higher machining efficiency—supporting high-speed cutting and shortening cycle times.

3. Better surface quality—meets the precision requirements of the brake disc friction surface.

4. Greater adaptability to operating conditions—high-temperature and impact resistance, suitable for interrupted cutting.
