ECM is the abbreviate of English Electro Chemical Machining, it is the floorboard of method of treatment of of all kinds electrochemistry. Electrochemistry treatment is a kind of treatment method that with electroanalysising the principle is a foundation, add man-hour workpiece to be dissolved in electrolyte, achieve treatment goal thereby. Nowadays, electrochemistry treatment method already was made in aerospace, car by wide application, instrument of accurate medical treatment is made, microscopical technology and energy technology domain. Craft electrochemistry treatment applies to all sorts of metals, tall even alloy, for instance nickel - titanium alloy, and the material after heat treatment. When electrochemistry is machined, workpiece and cutting tool do not generate a contact, so disappear machines all defect of the law besides the tradition, if cutting tool wears away,big, meeting produces mechanical stress, because spare parts be heated is met,produce surface of microcosmic crack, workpiece to be able to form oxidation layer, meeting to form 2 class burr to wait for blemish. Active force of instrument of the inorganic when electrochemistry machines the marked characteristic of craft namely, without burr, transfer pliable, surface is bright and clean degree tall. Advantage cutting tool (cathode) wear away little, for batch so production created optimal condition. The surface is bright and clean degree can amount to Ra 0.

05 accurate treatment won't bring to bear on to workpiece machinery and the negative effect that cause by heat, because this won't cause the change of structure of metallic stuff organization. Won't affect material character to won't change hardness, tenacity and magnetism to be able to machine a wall the outline workpiece surface with thin, small figure is bright and clean spend repeat precision high production technology is simple, reliable, efficient, need not go burr or polish this kind hind treatment finishs rough machining inside a working procedure / finish machining / polishing can be machined exceeding alloy material macrostructure and micromechanism to be able to machine treatment craft electrochemistry at the same time is the treatment method that with electroanalysising the principle is a foundation, an electrode regards cathode and direct current source as join.

Workpiece regards the anode of another electrode and power source as join. Charge exchange produces between the cathode in electrolyte and workpiece, zincous workpiece is dissolved. Need not contact workpiece so but narrow the different outline that processes a work, annular channel, straight chamfer and annular chamfer. After the material after dissolving and electrolyte form metallic hydrate, can go out from the filter in electrolyte. Electrochemistry treatment does not suffer workpiece to organize structural influence, because this can process soft and rigid data. When using electrochemistry method to machine, workpiece both neither bears thermic load, also won't produce mechanical stress. CNC Milling
