Cutting Inserts Designed For Aerospace Alloy Turning - ATI Stellram ATI Stellram designed the 4E Turning Geometry to meet the demands of machining aerospace-type components manufactured from stainless steels, high nickel, high cobalt and titanium-based alloys. Available in grade SP0819, the inserts use an approved aerospace substrate, and they are enhanced with a nano-TiAIN layer physical vapor deposition (PVD) coating. The combination of a hard coating with micro-grain carbide substrate improves heat and wear resistance in high-temperature alloy machining. This enables longer tool life and higher productivity. The chipbreaker profile with positive cutting action reduces edge build-up, leaving a smooth surface finish and greater component-dimension integrity. |
