Milling of stainless steel with end mill
An OEM customer is looking for a coating to improve the 8 mm square cemented carbide end mill used to mill 1.4122 stainless steel. The milling process uses coolant, at a tool rotation speed of 8000 rpm and a cutting speed of 201 m/min. Axial depth is 8 mm and radial depth 0.4 mm.
- Low thermal conductivity; heat transfer happens through the tool and not through the chips
- High wear
- Tendency toward notching, and chipping of the cutting-edge radius
- Good temperature resistance wear
- High hardness
- Allowing a sharp edge to reduce cutting forces and further heat generation
Our coating recommendation
Hardcut™ Plus, a TiSiN based multi-layer coating, has been developed for high speed end-milling and gear hobbing of the hardest and toughest materials including exotic nickel and titanium alloys unde…
