High-Security Finisher | Miracle PVD Coating | FM Chipbreaker Geometry
Grade Technology & FM Geometry
VP15TF Grade (The Miracle PVD): A premium PVD (Physical Vapor Deposition) coated carbide grade. The Miracle Coating (TiAlN-based) offers extreme heat resistance and a low coefficient of friction. This prevents Built-Up Edge (BUE), which is common when finishing gummy materials like 304/316 Stainless Steel.
FM Chipbreaker (Chip Control Mastery): The FM designation is Mitsubishi’s premier finishing geometry. Even with a larger 0.8mm radius, the FM rake angle is sharpened to slice through material, ensuring that chips break cleanly at shallow depths of cut, protecting the surface finish and the machine operator.
0.8mm Edge Security Radius: The 08 (1/32") radius provides superior edge toughness compared to smaller radii. It allows for a higher feed rate during finishing passes and provides the necessary strength to handle light interrupted cuts or "skin" on forged parts.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T308-FM | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | CCMT32.52-FM | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Finishing Parameters
*The 0.8mm radius allows for higher feed rates, but ensure the depth of cut stays within the FM chipbreaker range.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 140 - 260 m/min | 0.10 - 0.25 mm/r | 0.30 - 1.50 mm |
| Stainless Steel (M) | 90 - 190 m/min | 0.08 - 0.20 mm/r | 0.30 - 1.20 mm |

FM (Finishing): Your first choice for clean surfaces and low cutting forces. Best for precision tolerances.
MW (Wiper): Switch to MW only if you need to double your feed rate while maintaining the same surface finish. However, MW generates much higher tool pressure than **FM**.

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.
