UE6020 Grade & MA Chipbreaker Detail
UE6020 CVD Coated Grade: Designed for the high-speed turning of steel. The UE6020 grade features a triple-layer coating (TiCN-Al2O3-TiN) that provides exceptional resistance to plastic deformation and flank wear. It is the first choice for continuous to lightly interrupted cutting of carbon and alloy steels.
MA Chipbreaker: The MA geometry is a universal "Medium-Range" breaker. It is specifically designed to provide stable chip control over a wide range of feed rates, effectively preventing chip entanglement and protecting the high surface finish of the workpiece.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel | 150 - 300 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.5 mm |
| Alloy Steel | 120 - 250 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |

UE6020 is the gold standard for high-speed steel turning. If your application involves heavy interrupted cutting or high-impact loads, consider switching to UE6110 or MC6025. For stainless steel machining, we recommend the VP15TF Miracle Coating grade for its superior anti-welding properties.
