- T-Slotting: Optimized geometry ensures stable chip flow and minimal vibration during t-slotting operations.
Recommended Cutting Conditions
Parameters are indicative; adjust based on machine rigidity, workpiece condition, and coolant strategy:
| Workpiece Material | Cutting Speed (m/min) | Feed (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|
| Cast Iron | 120-200 | 0.05-0.30 | 0.10-2.00 |
| Aluminum Alloy | 300-600 | 0.05-0.25 | 0.10-1.50 |
| Titanium Alloy | 30-60 | 0.05-0.20 | 0.10-1.00 |
| Non-Ferrous | 150-400 | 0.05-0.30 | 0.10-2.00 |
Operating Guidelines
- Always verify insert seating and clamping force before starting spindle.
- Use minimum quantity lubrication (MQL) or dry machining for non-ferrous materials with KW10.
- Monitor flank wear (VB) and replace insert when wear land exceeds 0.3 mm for finishing or 0.6 mm for roughing.
- Ensure workpiece rigidity and toolholder overhang are within manufacturer recommendations.
- For titanium alloys, reduce cutting speed by 30% compared to aluminum to prevent thermal damage.
Toolholder Compatibility
Compatible with standard ISO toolholders conforming to METS series specifications. Recommended clamp systems: lever-lock or screw-lock depending on insert thickness and machine stability. Verify holder designation matches insert style SDMT and inscribed circle 0.315" for optimal seating and repeatability.
