What is Electrochemical Grinding 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.
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour
An electrolyte is pumped into a small gap between the workpiece and a rotating abrasive grinding wheel. Metal is removed from the electrically conductive workpiece by electrochemical attack and abrasion. Protruding abrasive grit particles on the grinding wheel remove electrochemical oxidation from the surface of the workpiece.
In Electrochemical grinding, the metal bonded grinding wheel filled with a nonconductive 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 kglitre of water.
The Burr Free Electrochemical Grinding process is a hybrid method of metal removal combining Abrasive Grinding and Electrochemical Machining or ECM. ECM is a nontraditional metal removal method developed many years ago based on Michael Faradays laws of electrolysis. Faraday found that metal can be dissolved when DC current flows across a
Electrochemical machining ECM is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte such as NaCl.
The measurements of diamond grinding wheels were done directly on the electrochemical grinder ESCB40 just after finishing of mechanical grinding and electrochemical ECG. There were following machining parameter applied U 6 V, F y 30 N, v c 20 ms, and electrolyte on the basis of NaNO 3 with additives.
ElectroChemical Grinding ECG is a combination of ElectroChemical Anodic dissolution of a material, according to Faradays Law, and light abrasive action. The metal is decomposed to some degree by the DC current flow between the conductive grinding wheel Cathode and the work piece Anode in the presence of an electrolyte solution.
However, in ECMbased combined processes such as electrochemical grinding ECG, electrochemical discharge machining, both ECM and the other processes participate in material removal. The resulting synergetic effect is a 113 effect which implies that the combined effect of ECM with other process energy is more than double the benefits of
Electrochemical Grinding is widely used for tube cutoff of materials such as stainless steel hypodermic needle tubing where deburring is not practical. The technology is also commonly used in aircraft applications such as fragile honeycomb materials and turbine airfoils.

electrochemical grinding ecg The electrochemical grinding process combines traditional electrochemical machining and grinding processes to remove material from a workpiece. With its burrfree cutting, tight tolerance capabilities and workability with stainless steel and other medical grade alloys, ECG is an integral technology in Wytechs
Burr Free Electrochemical Point Grinding System. When added to the Tridex Model SG1645 or SG 2060 electrochemical grinders, the PGS100 is a fully programmable pointing and material handling system to manufacture a wide variety of medical device points on tubing or solid wire using electrochemical grinding technology ECG.
A Closer Look at ECG Electrochemical 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.
The electrochemical grinding process bears some resemblance to creepfeed grinding, in that both feed material more slowly than conventional surface grinding. However, while creepfeed can be used to enhance surface finish, that method was designed mainly for removing large amounts of material in one pass.
Electro Chemical Grinding ECG Electrochemical grinding combines both electrolytic action 90 and physical grinding 10 to provide precision, burrfree and stressfree results. Owing to the electrolytic reaction, ECG eliminates the need for a separate deburring operation.
To study the influence of process parameters in electrochemical grinding process. Objective To understand the operating principle of electro chemical grinding process. T o understand the process paratemeters affecting the process.
Electrochemical Grinding is also an alternative to wire EDM, sinker EDM, milling, turning, and traditional grinding in terms of cost, processing time and finish. What is Electrochemical Grinding Here is a video to learn a little more about Electrochemical Grinding Get A Quote Name.
Electrochemical machining ECM is a nontraditional machining process uses the principle of Faraday to remove metal from the workpiece. Electrolysis is based on Faraday laws of electrolysis which is stated as. weight of substance produced during electrolysis is proportional to current passing, length of time the process used and the equivalent weight of material which is deposited.
