VP15TF Miracle PVD Grade
The VP15TF grade is Mitsubishi's high-tech PVD coated carbide. Known for its extreme versatility, it combines a micro-grain carbide substrate with a nano-layered Miracle coating. This provides exceptional thermal shock resistance and edge toughness, making it the primary choice for milling stainless steel and difficult alloys under wet or dry conditions.
JL (Low Resistance) Breaker
The JL Chipbreaker is specifically designed for light-to-medium milling where reducing cutting forces is critical. The sharp rake angle prevents the material from "smearing" and minimizes work hardening on the workpiece surface. Ideal for thin-walled parts or long-overhang setups where vibration (chatter) is a concern.
Milling Parameter Recommendations
| Material Group | Cutting Speed ($v_c$) | Feed per Tooth ($f_z$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 100 - 180 m/min | 0.08 - 0.20 mm/t | 0.5 - 4.0 mm |
| Titanium/Inconel | 30 - 60 m/min | 0.08 - 0.15 mm/t | 0.5 - 3.0 mm |
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.
