钛合金是比强度高、耐蚀性、耐热性具佳的轻金属材料。在航空、汽车、深海潜水艇、生物体用材等方面有广泛应用。 然而,钛合金的导热率仅为铜的六十分之一,切削加工时易产生热量集中,导致工具磨损加剧,是典型的难切削加工材。 电火花加工时,工具电极与被加工物体不接触,故对材料的机械性能几乎没有影响。可作为难切削加工材料钛合金的加工
Titanium alloy is a light metal material with high strength, corrosion resistance and heat resistance. In aviation, automobiles, deep-sea submarines, biological materials and other aspects of a wide range of applications. However, the thermal conductivity of titanium alloy is only one-sixtieth of copper, heat treatment is easy to produce concentrated, resulting in increased tool wear and tear, is a typical hard-to-cut material. EDM, the tool electrode and the object is not in contact with the processed, so the mechanical properties of the material has almost no effect. Can be used as hard machining of titanium alloy processing
