MC6015 Grade Advantage
The MC6015 grade is Mitsubishi's ultimate high-speed CVD steel turning grade. The Nano-Texture coating creates an extremely smooth surface that prevents built-up edge (BUE) and allows for ultra-high cutting speeds ($v_c$). It is designed for maximum efficiency in stable machine environments.
MA Chipbreaker Logic
The MA chipbreaker is a versatile medium-cutting geometry. It balances a sharp cutting edge with high structural strength, ensuring consistent chip control across various depths of cut. This geometry minimizes thermal load on the tool tip during long-running steel turning operations.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (S45C) | 280 - 500 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
| Alloy Steel (SCM440) | 220 - 400 m/min | 0.15 - 0.40 mm/rev | 0.8 - 3.5 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.
