UE6020 Grade & Geometry Analysis
UE6020 Grade: This is a dedicated CVD coated carbide grade specifically optimized for general-purpose steel turning. It features a tough substrate combined with a multi-layer coating that combats crater wear and flank wear, even during fluctuating cutting conditions. It is ideal for ISO P20-P35 applications.
Cutting Geometry: The negative 35-degree angle provides high edge strength for precision profiling. It is designed to minimize work hardening on the workpiece surface while maintaining stable chip flow during medium-range cutting.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Low Carbon Steel | 150 - 300 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.0 mm |
| Alloy Steel (SCM) | 120 - 250 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |

UE6020 is your "Universal Choice" for stable steel machining. If you are performing high-speed continuous cutting on carbon steel, we recommend upgrading to UE6110. For heavy interrupted cuts where impact is high, the tougher UE6035 grade will prevent premature edge chipping.
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.
