VP15TF Grade & Geometry Analysis
VP15TF Miraculo Coating: This PVD coated carbide features a micro-grained substrate that balances hardness and toughness. The coating reduces built-up edge (BUE), which is common when machining 304/316 stainless steel. The PVD process allows for a sharper cutting edge than CVD, significantly reducing cutting forces.
Stable Profiling: The 35° diamond shape offers superior accessibility for complex precision profiling. The chipbreaker design ensures effective chip control even at varying depths of cut, protecting the workpiece surface from scratches.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (M) | 80 - 180 m/min | 0.15 - 0.35 mm/rev | 0.8 - 3.0 mm |
| Carbon/Alloy Steel (P) | 100 - 220 m/min | 0.15 - 0.40 mm/rev | 1.0 - 3.5 mm |

VP15TF is the "Universal Solution" for mixed-material jobs. For high-speed mass production of only carbon steel, the UE6110 (CVD) is faster. For difficult-to-cut superalloys (Inconel/Titanium), consider the MP9015 grade. For mirror-finish finishing on steel, use the NX2525 cermet grade.
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.
