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.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
