Thick Cross-Section Stability | CVD UE6020 Grade | MA Precision Control
Rigid Engineering for Steel Mastery
UE6020 Grade (Advanced CVD Coating): The UE6020 is Mitsubishi's benchmark for steel turning. This CVD grade features a multi-layer coating designed to withstand high-speed friction. It excels in Carbon Steel (P20-P30 range) and Alloy Steels, offering a perfect balance between wear resistance and edge toughness for general workshop use.
MA Chipbreaker (Precision Medium Cut): The MA geometry is designed for medium-range machining. Its unique rake surface ensures stable chip breaking even at lower feed rates. This prevents surface scratching from "long chips" and ensures that heat is efficiently transferred into the chip, away from the cutting edge.
06 Thickness (Extra Thermal Mass): The 6.35mm (06) thickness provides more volume than standard 4.76mm inserts. This leads to better heat dissipation and prevents plastic deformation during long, continuous cuts on large diameter parts.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness (S) | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150604-MA | 12.70 mm | 6.35 mm | 0.40 mm |
| Imperial | DNMG441-MA | 1/2" | 1/4" | 0.0157" (1/64") |
Recommended Cutting Parameters
*The 06 thickness allows for slightly higher speeds in stable setups. Use coolant for consistent chip control.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C) | 180 - 320 m/min | 0.10 - 0.25 mm/r | 0.50 - 3.00 mm |
| Alloy Steel (4140) | 140 - 280 m/min | 0.10 - 0.20 mm/r | 0.50 - 2.50 mm |
Compatible Tool Holders
Works with any standard 15-series 55° diamond holder (Ensure shim is compatible with 6.35mm thickness):

UE6020 (General Purpose): The most common choice for stable, general turning in mild to medium carbon steels. Excellent for general job shops.
MC6025 (High Edge Toughness): Switch to MC6025 if you are dealing with heavy interrupted cuts or machining rough outer scale. UE6020 is better for continuous turning at higher speeds.

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.
