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 |
