Advanced Grade & Chip Control
US735 Grade: This CVD-coated carbide grade is the first choice for interrupted cutting of stainless steel. It features a specialized substrate that absorbs impact and a coating that resists built-up edge (BUE), significantly extending tool life compared to standard inserts.
Finishing Chipbreaker: The VCMT160404 is designed for light-to-medium depths of cut, providing excellent chip curling even at high feed rates, ensuring your CNC machine runs without "bird-nesting."
Technical Cutting Parameters
For optimal performance in stainless steel turning, we recommend the following parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless (304/316) | 80 - 170 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.0 mm |
| Alloy Steel | 100 - 200 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
