Key Advantages

Extreme Wear Resistance: CBN material offers superior hardness and excellent thermal stability, outperforming carbide inserts in high-temperature machining

Optimized VNGA Geometry: Negative rake design reduces cutting forces, improves chip control, and enhances machining stability

High Precision Finish: Delivers superior surface quality and tight tolerances, reducing or eliminating the need for secondary finishing

Wide Compatibility: Fits standard tool holders for easy installation without modifying existing production lines

Cost-Efficient: Extended tool life and reduced downtime lower per-part processing costs in high-volume production

1.D-type CBN tools with single-edged tips excel in high-precision machining. Coatable CBN edges enhance tool longevity, ideal for precision components.

2.D-type CBN inserts with double-edged tips are optimized for high-volume, high-precision production. Featuring multiple cutting edges, they reduce tool wear and promote resource conservation—ideal for sustainable manufacturing at scale.

3.D-type CBN inserts with four-edged tips optimize high-volume production. Multiple cutting edges drastically reduce tool wear and promote sustainable manufacturing—ideal for eco-conscious mass production.

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

Application Scenarios

Hard Turning: Ideal for machining gears, bearings, shafts, and other automotive/aerospace components made of 45–65 HRC hardened steel
Cast Iron Machining: Efficiently processes gray iron, ductile iron, and compacted graphite iron for engine blocks and brake discs
High-Speed Finishing: Suitable for precision finishing operations requiring tight tolerances and smooth surface finishes
