Application Map by Operation
| Operation | Suitability | Priority |
|---|---|---|
| Drilling | Recommended | Primary |
| Boring | Suitable | Secondary |
| Chamfering | Suitable | Secondary |
| Spot Facing | Conditional | Secondary |
Recommended Cutting Conditions
Parameters are indicative; optimize based on machine rigidity and setup:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth ap (mm) |
|---|---|---|---|
| Carbon Steel (≤HB 200) | 132-152 | 0.16-0.21 | 4.5 |
| Alloy Steel (HB 200-280) | 112-132 | 0.16-0.19 | 3.6 |
| Stainless Steel | 92-112 | 0.14-0.16 | 2.7 |
| Cast Iron (HB 180-260) | 122-142 | 0.18-0.24 | 5.3 |
Note: Reduce cutting speed by 15-20% for interrupted cuts or less rigid setups. Use coolant for stainless steel and heat-resistant alloys.
Operating Guidelines
- Ensure toolholder runout is below 0.01 mm for optimal hole accuracy
- Use through-coolant toolholders for deep-hole applications (>2×D)
- Verify insert seating and clamping force before each operation
- Monitor flank wear; replace insert when VBmax exceeds 0.3 mm
- Apply appropriate entry strategy (pre-drill or ramp entry for solid material)
- Maintain consistent feed rate to avoid chip packing and insert fracture
