Note: Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and hole depth.
Operating Guidelines
- Coolant: High-pressure internal coolant (70+ bar) recommended; minimum 5% emulsion concentration
- Runout: Maintain TIR <0.01 mm at the tool tip for optimal tool life
- Peck Cycle: For holes >3×D, use peck depth of 1–1.5×D with full retract
- Entry Angle: Use chamfer or center drill for entry; avoid drilling into uneven surfaces
- Speed/Feed Ramp: Reduce speed by 30% and feed by 20% for first 1×D entry
- Tool Life Indicator: Monitor flank wear; regrind or replace at VB = 0.3 mm
