ATI Stellram designed the 4E turning geometry to meet the demands of machining aerospace-type components manufactured from high nickel, high cobalt and titanium-based alloys. Available in grade SP0819, the inserts use an approved aerospace substrate and are enhanced with a nano-TiAlN layer PVD coating.
Combining a super-hard coating with a micro-grain carbide substrate significantly improves heat and wear resistance in high-temperature alloy machining, the company says. This can enable longer tool life and higher productivity.
For versatility, the inserts are designed to machine a variety of materials. This can reduce shop inventory, operator error and cost.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
