Grade & Chipbreaker Analysis
US735 Grade (CVD Coating): This is a dedicated grade for stainless steel turning. It features a specialized carbide substrate that prevents thermal cracking and built-up edge (BUE), making it perfect for tough-to-machine materials like 304 and 316 stainless steel.
Standard Chipbreaker: Optimized for finishing and medium cutting, ensuring smooth chip evacuation and reducing cutting force on delicate workpieces.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.05 - 0.25 mm/rev |
| Heat Resistant Alloys | 30 - 70 m/min | 0.05 - 0.20 mm/rev |
Pro Tip: Grade Comparison
- US735: Best for interrupted cutting and general stainless steel machining (High Toughness).
- VP15TF: A versatile alternative for small-diameter parts and stable cutting conditions.
- MC7025: Choose this for higher speed continuous cutting in stable environments.
