May 12, 2020 Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece anode before they have a chance to plate onto the tool cathode. Modification of this process are used for turning, facing, slotting ...
Jul 24, 2020 Either electrochemical machining ECM or CNC milling can be the better choice, depending on the situation. PECM is advantageous as a non-contact, non-thermal process that is compatible with any conductive metal or alloy. With PECM, thin walls, speed, repeatability, and low surface roughness are all possible.
Electrolytic processing. A method of forming a metal material by an electrochemical reaction in which an anode is dissolved. When the tool cathode is continuously propelled to the workpiece, the current density is the highest, and the anode of the workpiece dissolves the fastest at the point where the gap is the smallest, because the gap between the two surfaces is not equal.
Mar 06, 2021 Electrochemical machinings are a non-traditional machining process. In the electrochemical machinings process, a combination of electrical energy amp chemical energy is used to remove material from the workpiece. This process is known as a reverse electroplating process, but this process removes the material rather than depositing it.
