| Gray Cast Iron | 90-170 | 0.20-0.60 | 2.0-8.0 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant application, and workpiece condition. Use water-soluble coolant for steel and stainless steel; dry or compressed air for cast iron.
10. Operating Guidelines
- Coolant: High-pressure water-soluble coolant (5-8% concentration) recommended for steel and stainless steel machining
- Entry Angle: Maintain 15-30° approach angle to minimize notch wear
- Tool Overhang: Keep to minimum possible; max 4× tool diameter for boring applications
- Insert Change: Inspect after 2-4 hours of cutting time; replace when flank wear exceeds 0.3 mm
- Edge Preparation: Standard hone (0.05 mm) for general use
- Workpiece Runout: Ensure TIR < 0.02 mm for optimal tool life and surface finish
