High-Velocity Steel Turning | UE6110 CVD Grade | MA Balanced Geometry
High-Speed Machining Specialist
UE6110 Grade (Advanced CVD Coating): The UE6110 is Mitsubishi’s premium grade for high-speed continuous turning of steel. It features an ultra-thick $Al_2O_3$ (Aluminum Oxide) coating layer that provides world-class thermal insulation. This allows the insert to operate at higher surface speeds than general grades, specifically in Carbon Steel and Alloy Steels (P10-P20 range).
MA Chipbreaker (Medium Cut Mastery): The MA geometry is the standard "M-Class" choice for medium turning. It is designed to provide stable chip control across a wide range of feed rates. The rake face reduces cutting resistance, which helps lower the heat generated at the tool-workpiece interface—critical for maintaining high velocities.
0.8mm Radius (Production Edge): The "08" (1/32") radius offers a robust cutting edge. It is less prone to vibration than a larger radius but much stronger than a 0.4mm tip, making it ideal for high-feed production where edge security and surface finish are both required.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408-MA | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432-MA | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*UE6110 is designed for high-speed continuous cutting. Avoid using at low speeds where built-up edge (BUE) occurs.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045/S45C) | 250 - 450 m/min | 0.15 - 0.40 mm/r | 1.00 - 4.50 mm |
| Alloy Steel (4140/SCM440) | 200 - 380 m/min | 0.15 - 0.35 mm/r | 1.00 - 3.50 mm |

Shop DDJNR 15 HoldersPro-Tip: UE6110 vs. UE6020
UE6110 (High-Speed Specialist): Use this grade for high-RPM mass production where the cut is clean and continuous. It is much more wear-resistant at extreme temperatures.
UE6020 (The General Workhorse): If you are turning a workpiece with keyways, hex shapes, or heavy scale, switch to UE6020. UE6110 is harder but more sensitive to mechanical shock.
