Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
Operating Guidelines
- Coolant: High-pressure internal coolant (≥70 bar) is strongly recommended for holes deeper than 3×D. Use water-miscible cutting fluid with 8-10% concentration.
- Peck Cycle: For micro-drills (<Ø1 mm), use peck depth of 0.5–1×D. For standard drills, peck at 2–3×D intervals.
- Runout: Maintain tool runout ≤ 5 µm at the tool tip for optimal tool life and hole accuracy.
- Pre-Drilling: For holes requiring high positional accuracy, use a dedicated spot drill with 90°–120° point angle.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent chipping of the cutting corners.
- Chip Evacuation: Verify adequate coolant flow and chip evacuation before increasing cutting parameters.
- Tool Inspection: Inspect cutting edges under magnification (≥20×) after every 30 minutes of cutting time.
Toolholder Compatibility
Micro-collet chuck (ER11/ER16) or precision hydraulic chuck with runout < 3µm
| Holder Type | Recommended Series | Taper / Size |
|---|---|---|
| ER Collet Chuck | ER11, ER16, ER20 | AT3 or better |
