Grinding, surface grinding, internal grinding ...
In comparison to electrochemical machining, electrochemical grinding is relatively similar. Basically, it is a combination of an electrochemical process and a grinding process used for metal removal. You may also hear it referred to as "anodic machining" or "electrolytic grinding". In the process, the part of a hode is played by the ...
The electrochemical cut off saw uses a copper abrasive blade in conjunction with a DC power supply and special salt solution. The combination produces a completely burrfree part with a zero defect level. Electrochemical cutting has many advantages over other methods. Fixtures are designed to hold multiple tubes or wires to be cut, limited only ...
Grinding is used for finishing, because it ensures a high surface quality. Polishing is the process of machining in which the removal of particles, is used to improve the appearance, to remove oxidation and formation of reflective surface.
Theory: Working principle of Electrochemical machining:Electrochemical machining is based on the electrolysis process as outlined in Fig. 1, the workpiece and tool are the anode and hode respectively, of the electrolytic cell, and a potential difference, usually about 10 V, is applied across them.
Abrasive grinding is an ideal alternative to conventional machining because of the high ductility and rapid work hardening of the material. Electrochemical grinding (ECG) combines the precision of abrasive grinding with the low force qualities of electrochemical process limits physical stresses, mechanical damage, and heat affect inherent to more conventional processes.
· The main purpose of Electrochemical machining is to machine and finish forging die cavities (die sinking) and to produce small holes. Versions of this process are used for slotting, trepanning, milling, turning, drilling, facing, and profiling, as well as in the production of continuous metal strips and webs. Shaped tube electrolytic machining (STEM), a modifiion of ECM is used for .
