|---|---|---|---|
| Carbon Steel | 60 - 80 m/min | 0.02 - 0.05 mm/rev | Emulsion / MQL |
| Alloy Steel | 50 - 70 m/min | 0.015 - 0.04 mm/rev | Emulsion / Oil |
| Stainless Steel | 40 - 60 m/min | 0.01 - 0.03 mm/rev | Oil / MQL |
| Cast Iron | 70 - 90 m/min | 0.03 - 0.06 mm/rev | Dry / Air Blast |
| Aluminum | 100 - 150 m/min | 0.03 - 0.08 mm/rev | Emulsion / Air |
| Steel | 55 - 75 m/min | 0.015 - 0.035 mm/rev | MQL Recommended |
Operating Guidelines
- Runout Tolerance: Maintain TIR ≤ 0.005 mm at the tool tip for optimal performance and hole quality.
- Peck Cycle: For depths > 2×D, use a peck drilling cycle with 1×D peck depth for diameters ≤ 1 mm.
- Coolant Strategy: High-pressure coolant (≥ 70 bar) is recommended for steel to ensure effective chip evacuation.
- Entry Angle: Use a chamfer or center drill to avoid burr formation and ensure stable entry.
- Spindle Speed: Calculate RPM based on Vc = 60 m/min for steel; adjust proportionally for other materials.
- Tool Overhang: Minimize overhang to reduce deflection; use collet chucks or hydraulic holders for best results.
- Re-sharpening: Not recommended for micro drills below 1 mm; replace at wear criteria of 0.03 mm flank wear.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER Collet Chuck (ER11/ER16) | ★★★★★ | Use precision collets (≤ 5 μm runout) |
