UE6110 High-Speed Grade
The UE6110 grade is Mitsubishi's premier solution for stable steel turning at elevated speeds. It features a multi-layered CVD coating (TiCN + Al2O3) with a specialized smooth surface treatment. This reduces frictional heat and prevents plastic deformation, making it ideal for continuous, high-efficiency machining in mass production.
MA Chipbreaker Geometry
The MA chipbreaker is the industry's versatile choice for medium cutting. It is designed to provide excellent chip control across a wide range of feed rates. The geometry minimizes cutting resistance, ensuring stable performance in CNC lathe operations and reducing the risk of workpiece surface damage from chip entanglement.
