采用电化学加工法切割难加工材料能够达到高的切割速度和优良的被加工表面质量;同时,工具不损耗;切削刃上没有毛刺与表层损伤。但是,由于钛及其合金对于电解液有增强的化学激活性,在被加工表面上形成氧化薄膜,因而使加工过程难于进行。清除这层氧化膜用机械法最适宜,而其中以金刚石磨削法特别有效。切割过程乃是金刚石磨削和电化学加工的综合,以毛坯作阳极,工具(金刚石砂轮)作阴极。在实现这种过程时对所加工的材料同时产生三种基本作用的机理:溶解阳极(毛坯)并在其上形成氧化膜的电化学过 The use of electrochemical machining of difficult-to-cut materials to achieve high cutting speed and excellent surface quality; at the same time, the tool does not consume; no burr on the cutting edge and surface damage. However, since titanium and its alloys have enhanced chemical activation of the electrolyte, an oxide film is formed on the surface to be processed, making the processing difficult to perform. Remove the oxide film is the most appropriate mechanical method, of which diamond grinding method is particularly effective. The cutting process is a combination of diamond grinding and electrochemical machining, using the blank as the anode and the tool (diamond wheel) as the cathode. There are three basic mechanisms that act simultaneously on the material being processed in the realization of this process: electrochemical oxidation of the anode (blank) and formation of an oxide film thereon
