Aerospace industry developed superalloys (hrsas) more and more applications to the terms of the automotive industry, medical equipment, semiconductor, and power plant equipment. Common superalloys have inconel 718,625, 沃斯帕洛伊 alloys, titanium 6al4v, now has added a titanium and aluminum-magnesium alloy. All of these materials gave the process more difficult.
Very hard superalloys, titanium hardness number up to 330 Brinell hardness. The use of traditional metal knives, cutting with a temperature as high as 2000 ° f, will weaken the binding molecules to form metal flow layer. And if superalloys tools throughout the cutting process, the tool will remain the same hardness.
When machining superalloys also have hardening phenomenon can cause premature failure of the blade. The difficulty of machining superalloys are many, not flaking material is covered with abrasive, its sharp edges even faster wear of the blade cutting edges.
