Material & Chipbreaker Details
Grade UE6020 (CVD Coated Carbide): This grade features a thick TiCN + Al2O3 coating. It is the first choice for P10-P30 steel applications. It offers extreme heat resistance and toughness, making it a reliable long-life turning insert for carbon and alloy steels.
MV Chipbreaker: Designed for medium-range cutting, providing excellent chip control at various depths of cut, reducing the risk of "bird-nesting" during CNC operations.
Recommended Cutting Parameters
To maximize tool life and surface finish, use the following starting values:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon Steel / Alloy Steel | 150 - 300 m/min | 0.15 - 0.40 mm/rev |
