WG / WH Type SUMIBORON One-Use Wiper Inserts

Product catalog summary

Introduction
SUMIBORON One-Use Wiper Inserts are designed for hardened steel machining, offering two types: WG and WH. These inserts feature a wiper edge to enhance surface finish and machining efficiency.

Specifications
The WG type is optimized for low-feed cutting (f ≤ 0.20mm/rev), while the WH type is suited for high-feed cutting (f ≥ 0.20mm/rev). Both types aim for a surface roughness range of Rz = 1.6µm to 3.2µm. Available grades include BN2000, BNC160, and BNC200.

Procedures and Recommendations
1. Use a holder with a 93° or 95° approach angle depending on the insert type.
2. Tool compensation is necessary as DNGA/DCGW and CNGA/CCGW/WNGA types do not follow ISO standards.
3. For continuous cutting, wiper inserts are recommended, while non-wiper inserts are better for copy turning.
4. Check workpiece rigidity and machine setup if chattering occurs.

Application Examples
Examples include machining carburized steel shafts and hardened steel pinion gears, demonstrating improved efficiency and surface finish with wiper inserts compared to standard inserts.
