Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece condition, and coolant application. Dry machining or minimal lubrication (MQL) is recommended for coated grades.
10. Operating Guidelines
- Coolant: Water-soluble coolant (5-8% concentration) or neat oil for stainless steel. Avoid sulfurized oils with copper-coated inserts.
- Run-in: Reduce cutting speed by 20% for the first 5 minutes to stabilize the cutting edge and coating.
- Tool Overhang: Minimize overhang to ≤ 4× tool diameter for optimal stability and surface finish.
- Insert Change: Index or replace insert when flank wear (VB) reaches 0.3 mm or when surface finish degrades below Ra 1.6 μm.
- Storage: Store in original packaging at 15-25°C, humidity <60%. Avoid direct sunlight.
- Handling: Use plastic or copper-tipped tools for insert clamping. Never strike carbide with hardened steel.
