Core Advantages

Extreme Hardness & Wear Resistance: Second only to diamond, the CBN material offers excellent abrasion resistance, which greatly reduces frequent insert changes and production downtime.

Ultra High-Temperature Stability: Maintains stable cutting performance even at temperatures above 1200°C, making it perfect for dry cutting and high-speed machining processes.

Long Tool Life & Cost Efficiency: Compared with ceramic and carbide inserts, TCGW CBN Inserts lower per-part machining costs by 20%–30% due to their longer service life.

Optimized TCGW Geometry: Trigon shape with 0° relief angle ensures strong stability and wear resistance, ideal for heavy-duty turning operations.

Multi-Layer Composite Structure: High-quality CBN layer bonded with tungsten carbide substrate enables fast heat dissipation and extends tool life.

1.T-type single-edged tool tips excel in precision finishing. Tools with back angles enhance CBN cutting performance, while coated edges extend tool life—ideal for high-accuracy components.

2.T-type CBN inserts with three-edged tips are optimized for high-volume production. Featuring back angles and coatable edges, these tools deliver extended tool life and reduced wear—ideal for large-scale manufacturing efficiency；

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

Application Scenarios

Automotive Industry: Perfect for machining hardened gears, shafts, brake discs and engine parts.
Aerospace Industry: Suitable for turbine components, landing gear and other high-tolerance structural parts
Die & Mold Making: Efficiently realizes precision finishing of hardened steel dies and molds, achieving mirror-like surface quality.
