PRODUCT DETAIL

CBN grooving inserts are specialized grooving tools made from CBN (a superhard material second only to diamond in hardness), specifically designed for machining high-hardness materials. They maintain stability at temperatures exceeding 1200°C, achieving cutting efficiency 3-5 times of conventional carbide cutters. They maintain a slot width tolerance of ±0.01mm and a slot surface roughness of Ra0.8-1.6μm. CBN grooving inserts are primarily used for machining hardened steel and cast iron and other parts. Common types of CBN slotting cutters are as follows:

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

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 cast iron and hardened steel. 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 limitation. CBN grooving inserts can be used for both roughing and semi-finishing.

CBN grooving inserts replace ceramic grooving inserts can reduce costs by 30% and increase tool life by 55%.

The advantages of CBN 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.
