Key Advantages

Extended Tool Life：Made of high-quality cubic boron nitride (CBN) material, whose hardness is second only to diamond, significantly reducing tool wear rate, decreasing tool change frequency and downtime, and lowering overall production costs.

High-Speed & Efficient Machining：Suitable for high-speed turning conditions, the machining efficiency is far superior to traditional carbide inserts, while ensuring the surface finish of workpieces without secondary polishing.

Grinding Process Replacement：Directly turning 45-65 HRC hardened steel, eliminating the grinding process, shortening the production cycle, and increasing productivity by more than 30%.

Outstanding Stable Performance：Excellent edge stability and thermal stability, suitable for continuous and interrupted cutting conditions, meeting the needs of high-volume and long-term stable production.

1.The single-edge tip of W-shaped CBN tools is suitable for processing high-precision and high-hardness products. The CBN cutting edge can also be coated, which can improve the service life of CBN tools.

2.The W-shaped CBN insert with six cutting edges is ideal for high-volume production, as its multiple edges reduce tool wear and contribute to environmental sustainability.

3.The W-shaped integral CBN insert is ideal for high-volume production, featuring multiple cutting edges and excellent strength to significantly reduce tool wear and conserve resources.

Notes: Edge rounding W=0.15mm; customizable for different workpiece materials.
