Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ✓✓✓ Optimal | Designed for full breakthrough with clean exit |
| Blind-Hole Drilling | ✓✓✓ Optimal | Flat bottom capability with reduced peck cycles |
| Peck Drilling | ✓✓ Recommended | Use 1.5D — 2D peck depth for deep holes |
| Helical Interpolation | ✓✓ Recommended | Suitable for oversized hole generation |
| Chamfering / Spotting | ✓ Possible | Limited by point geometry; use dedicated spot drill |
| Stack Drilling | ✓✓ Recommended | Consistent chip control across multiple plates |
Recommended Cutting Conditions
Parameters are provided as starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Carbon Steel (C45) | 70.0 | 0.13 — 0.3 | 4456 |
| Stainless Steel (304) | 52.0 | 0.111 — 0.255 | 3310 |
| Aluminum Alloy (6061) | 175.0 | 0.182 — 0.42 | 11140 |
| Cast Iron (GG25) | 63.0 | 0.143 — 0.33 | 4010 |
| Hardened Steel (HRC 45) | 42.0 | 0.091 — 0.21 | 2673 |
Operating Guidelines
- Coolant: High-pressure internal coolant (20–70 bar) is strongly recommended for chip evacuation and heat dissipation. Minimum 5% emulsion concentration.
- Peck Cycle: For holes deeper than 3×D, use peck drilling with 1.5D–2D peck depth. Reduce feed by 20% on retraction.
- Entry Angle: Ensure perpendicular entry within ±1°. Use a spot drill for inclined surfaces >5°.
- Speed Ramp: Start at 80% of recommended Vc for the first 50 holes, then increase to 100% after tool wear stabilizes.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB > 0.3 mm or when burr formation exceeds specification.
- Storage: Store in original packaging at 15–25°C with <60% relative humidity. Avoid contact with other tools to prevent edge damage.
