The machine is intended for the electrochemical rifling of steel pipe parts.
The workpiece is mounted on supports and fixed. An electrode tool is inserted into the hole in the workpiece coaxially with the hole. Turn on the supply of electrolyte, technological current and movements of electrode tool.
ECM process is based on the anodic dissolution of metal and removing the process byproducts from the work area by the electrolytic fluid. The dissolution mechanism in electrochemical machining is based on the electrolysis process. The metal is removed according to Faraday's law, under which the amount of metal removed is proportional to current and machining time. One of the electrodes (workpiece) is connected to the positive pole of the source and constitutes an anode; the second electrode (tool) is connected to the negative pole and constitutes a cathode.

• One part is machined in one operation.
• Installation, removal of the part and electrode tools is carried out manually.
• The machining cycle is carried out automatically by the control program.
