Examples of high-speed milling of titanium parts

Titanium alloy has high strength, high fracture toughness, good corrosion resistance and weldability. Because it is more difficult to process than ordinary alloy steel, titanium alloys are generally considered to be difficult to process materials. The metal removal rate of a typical titanium alloy is only about 25% of that of most ordinary steels or stainless steels. Therefore, the time required to machine a titanium alloy workpiece is about 4 times that of machining a steel part.
   The following are two examples of machining aerospace titanium alloy parts with ATIStellram cutters and X-Grade blades.

Titanium alloy outer cover
