Application Map by Operation
| Operation | Feed (mm/rev) | Depth (mm) | Priority |
|---|---|---|---|
| Finishing | 0.05-0.15 | 0.1-0.5 | ★★★☆☆ |
| Semi-Finishing | 0.10-0.25 | 0.3-1.5 | ★★★☆☆ |
| Medium Machining | 0.15-0.35 | 0.5-3.0 | ★★☆☆☆ |

| Interrupted Cutting | 0.15-0.40 | 1.0-4.0 | ★☆☆☆☆ |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Depth ap (mm) |
|---|---|---|---|
| Carbon & Alloy Steel | 150-300 | 0.08-0.30 | 0.20-2.50 |
| Stainless Steel | 100-200 | 0.08-0.30 | 0.20-2.50 |
| Cast Iron | 80-160 | 0.08-0.30 | 0.20-2.50 |
Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece condition, and coolant application.
Operating Guidelines
- Speed Selection: Start at lower end of Vc range and increase gradually while monitoring tool wear and surface finish.
- Feed Rate: Use minimum feed for finishing; increase for roughing while maintaining chip thickness below 0.3 mm for optimal chip control.
- Depth of Cut: For finishing, keep ap below 0.5 mm. For roughing, ensure ap exceeds nose radius by at least 3× to avoid notch wear.
- Coolant: Flood coolant recommended for steel and stainless steel. For cast iron, dry machining or minimal mist is preferred.
- Tool Overhang: Minimize overhang to reduce vibration. Use shortest possible toolholder for the application.
- Insert Seat: Ensure holder seat is clean and free of chips before clamping. Torque clamping screw to 3.5-4.5 N·m.
- Edge Preparation: This insert features a 0.15 mm honed land. Do not re-sharpen or alter edge geometry.
Toolholder Compatibility
| Holder Type | Compatible Series | Approach Angle |
|---|---|---|
| Negative (0° clearance) toolholders with 80° or 35° approach angle | MWLNR/L, MWLNR/L, PWLNR/L (Trigon 80° negative holders) | Per ISO standard for W-inserts |
Holder Selection Tips: Choose a holder with sufficient chip clearance for the insert thickness (4.76 mm). For WNMG080408, ensure the holder clamping mechanism matches the insert hole diameter (4.4 mm).
