Values are starting recommendations. Adjust based on machine rigidity, coolant application, and workpiece condition. Wet cutting recommended for stainless steel and titanium.
10. Operating Guidelines
- Tool Overhang: Minimize overhang to maintain rigidity; use 4× diameter rule for boring bars.
- Coolant: High-pressure coolant (≥70 bar) recommended for chip evacuation in deep cavities.
- Entry Angle: Maintain 45°–75° entering angle for optimal chip thinning and edge load distribution.
- Edge Preparation: NA geometry comes with standard edge 0.03 mm for versatile performance.
- Inspection: Check insert seat and clamping screw torque (2.5–3.5 N·m) before each shift.
- Indexing: Rotate or flip insert when flank wear reaches 0.15–0.20 mm to maximize edge utilization.
