CCMT09T302 UE6020
Precision Steel Turning | CVD Coated Carbide | 0.2mm Radius
Engineering & Coating Specs
UE6020 Grade (CVD Coated Carbide): This grade is engineered for **General Steel Machining (ISO P20-P35)**. It utilizes a thick multi-layer coating (TiCN + Al2O3 + TiN). The Aluminum Oxide (Al2O3) layer provides excellent heat resistance, protecting the carbide substrate from crater wear during continuous high-speed turning.
0.2mm Corner Radius (RE): The ultra-sharp 0.2mm radius is designed to reduce radial cutting forces. This is critical for Internal Boring on small diameters or when machining thin-walled parts, as it significantly reduces vibration (chatter) and dimensional drift.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T302 | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | CCMT32.50.5 | 0.375" (3/8") | 0.156" (5/32") | 0.0079" |
Recommended Cutting Parameters
*The 0.2mm radius is precision-focused. Maintain lower feed rates to protect the sharp corner.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C) | 140 - 280 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.00 mm |
| Alloy Steel (4140) | 120 - 240 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |

UE6020 (CVD): Optimized for high-speed **Steel only**. It offers higher heat resistance but is less effective on Stainless Steel.
VP15TF (PVD): The ultimate "Multi-Material" grade. Choose VP15TF if you switch frequently between **Steel, Stainless Steel, and Cast Iron**, or if you have heavy interruptions.

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.
