It is a process that is quite similar to the electrochemical machining. As per the name, it is the metal removal process which is nothing but the combination of the grinding process and electrochemical process. It is also termed as the electrolytic grinding and anodic machining. In this technique, the workpiece plays the role of the anode while the grinding wheel works as a cathode. Some of you may be thinking about the electrolytes used in this process? Well, you can use a number of electrolytes. These include: Sodium Carbonate, Sodium Hydroxide, Sodium Chlorate, Sodium Nitrate, etc. The grinding wheel is the circular metal plate that consists of abrasive particles of Silicon Carbide, Boron Carbide, Aluminium Oxide, and Diamond Dust. The electrolytic fluid is pumped through the gap between the workpiece and the grinding wheel. Here, the reaction between the electrolytic fluid and the workpiece removes most of the metal while the abrasive material from the grinding wheel removes...

It is time to throw lights on the advantages of the electrochemical grinding: 1. The main advantage of this process is that it takes place in a very short span of time. 2. It is a smoother process than any other machining processes. 3. Sometimes many machining processes result in damage to the workpiece but in case of the electrochemical grinding, the workpiece is not get affected at all. 4. Also, it causes the wear and tear of the grinding wheel in a very small proportion. 5. It is a highly effective metal removing process because in this process most of the metal is removed due to the electrochemical reaction between the anode and cathode. 6. This machining process does not produce heat at the metal surface.
As we all know that every process has its advantages as well as its disadvantages and the same fact holds true for the electrochemical grinding. There are also several drawbacks of it and these are: 1. This technique of metal removing sometimes leads to the corrosion of the surface of the workpiece. 2. This process is applicable to very selective materials. Here, the materials of the workpiece as well as the grinding wheel must be conductive. 3. Some of you may be looking for applying this process to the workpieces that have cavities. But the bad thing is that you cannot use this process on the materials that contain cavities. 4. Though it is smoother and faster than traditional machining processes, it is a little bit complicated. 5. Another downside of this process is that it requires a skilled person to carry out the process. As it needs skilled labor, it is expensive to implement this process.
Following are the application so the electrochemical grinding that you must know: 1. This process is used for materials that are very hard such as stainless steel. In the case of harder materials, it removes the metal 10 times faster and smoother than the traditional machining process. 2. This is the perfect process that helps you in grinding the turbine blades. 3. It is widely used in the aerospace industry. 4. This type of machining process is also used in the sharpening of the needles. 5. It is used for eliminating the defects on the metal surfaces. In this article, we took a brief glance at the electrochemical grinding. Hope this article will help. If you really got some worthy knowledge after reading this article then, dont hesitate to share this article!
In Electrochemical grinding, the metal bonded grinding wheel filled with a non conductive abrasive. The grinding wheel act as a cathode and the workpiece is act as an anode. The electrolyte, which is usually sodium nitrate, sodium chloride, potassium nitrite, with a concentration of 0.150 to 0.300 kg/litre of water.
Galena has different electrostatic potentials from grinding medium. Collision and friction occur between them in the grinding process, which lead to electron transfer and charge redistribution on galena surface, affecting surface oxidation and galena recovery.
These delocalized electron orbitals can serve as charge transfer sites, ... The solvent used for the grinding process was N methy 2 pyrrolidone solution. Eventually, a uniform slurry was ...
