Processing characteristics of titanium alloy : small thermal conductivity, high cutting temperature; short contact length between chip and rake face, large tool tip stress; high strength, high hardness and high impact toughness of titanium alloy, work hardening is very serious; The friction speed is high; the titanium and titanium alloys have high chemical activity at high temperature, chemically react with oxygen and nitrogen in the air to form a brittle layer and reduce plasticity; the elastic modulus is small, and rebound is easy to occur. Walter Titanium Cutting Solutions - Duo Protostar ® Ti40/Ti45 Solid Carbide is designed for titanium alloys, Ti40 is a roughing tool with internal cooling, and Ti45 is a finishing tool. In a project by Airbus, the Ti40 tool tripled the machining life of a Ti6Al4V material workpiece. The maximum cutting capacity is 80cm 3 /min (V c =25m/min) and the diameter of the HSS-E tool is 32mm. Walter's flagship product for difficult-to-machine materials is the Tiger·tec material (PVD-Tiger) with PVD alumina coating, which is for the (ISO-S) material group containing titanium alloy materials. Two other materials – the WSM35 with high wear resistance and the extremely strong WSP45 – are now available. The G77 geometry is designed for use in titanium alloys. Its greatest feature is a 20° rake angle and a special micro-groove on the geometry.
