TPMH160304-MV UE6020
Mitsubishi Materials | Heavy-Duty CVD Coated Steel Turning
Engineered for High-Speed Large Diameter Boring
The Mitsubishi TPMH160304-MV UE6020 is a robust CVD coated carbide insert designed for high-efficiency turning of large steel workpieces. Utilizing the UE6020 grade, which features a thick Alumina thermal shield, it thrives in continuous high-speed cuts that would degrade standard tools. This long-tail steel turning specialist utilizes the MV chipbreaker to ensure consistent chip fragmentation in CNC boring of Carbon Steels and Alloy Steels.

CVD Grade UE6020 Technology
The UE6020 grade is the champion of high-productivity steel turning. By using Chemical Vapor Deposition (CVD), Mitsubishi applies a thick, layered coating that acts as a massive heat barrier. This enables significantly higher surface speeds ($v_c$) while preventing crater wear and plastic deformation in Carbon and Alloy Steels.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is a medium-finishing geometry designed for versatility. On the larger TPMH16 platform, it provides stable chip control across varying depths of cut. This is critical for preventing chip entanglement in large-scale boring operations and maintaining a superior workpiece finish.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.05 - 0.20 mm/rev | 0.3 - 2.5 mm |
| Alloy Steel (Medium Hard) | 120 - 280 m/min | 0.05 - 0.15 mm/rev | 0.2 - 2.0 mm |
