VP15TF Miraculo Grade & Geometry
VP15TF Grade: The VP15TF Miraculo PVD coating is a multi-layered TiAlN based coating that provides exceptional oxidation resistance and hardness. Unlike CVD coatings, PVD ensures a sharp cutting edge, which is critical for reducing cutting forces and preventing built-up edge (BUE) in gummy materials like 304/316 stainless steel.
Versatile Chipbreaker: The VNMG profiling geometry is designed for narrow access machining. Its chipbreaker allows for excellent chip control across a wide range of feed rates, making it an ideal choice for both finishing and light medium-duty applications.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (300 Series) | 80 - 180 m/min | 0.05 - 0.20 mm/rev | 0.3 - 2.0 mm |
| Carbon/Alloy Steel | 100 - 220 m/min | 0.05 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Heat Resistant Alloys | 30 - 70 m/min | 0.05 - 0.15 mm/rev | 0.3 - 1.5 mm |

VP15TF is your "Universal Soldier"—best for general purpose, stainless steel, and varied batch work. If you are doing high-speed mass production of carbon steel only, we recommend the UE6110 (CVD coated) for better high-heat performance. For mirror-finish finishing on steel, consider 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.
