Hydrogen sulfide is a very dangerous, toxic and corrosive gas. In the process, workpiece is taken as anode and tool is taken as cathode. No public clipboards found for this slide. Electrochemical grinding (ECG) technique composed of electrochemical machining (ECM) and mechanical grinding is a proper method for machining of difficult-to-cut alloys. Now customize the name of a clipboard to store your clips. 4 schematically shows an electrochemical drilling unit. Electro Stream Drilling(ESD) The hole aspect ratio (depth/diameter) reaches 8.6. Electrochemical machining (ECM) is a non-conventional manufacturing process which relies on duplicating the shape of the tool electrode into the workpiece via the anodic dissolution of the workpiece. As per the name, it is the metal removal process which is nothing but the combination of the grinding process and electrochemical process. • The equipment used is similar to conventional grinder except that the wheel is a rotating cathode with abrasive particles.

The process is virtually untraceable and unregulated. It is only at the drilling stage that oxygen-contaminated flu-ids are first introduced. Electrochemical Grinding (ECG) • Combines electrochemical machining with conventional grinding. Debris of Metal hydroxides generated in this process is dissolved by acidic electrolyte. And, best of all, most of its cool features are free and easy to use. See our Privacy Policy and User Agreement for details. The two electrodes workpiece … Generally impurity (more active metal) act as anode and original metal act as cathode so anode is the area where corrosion occurs. Siddharth Thakur (R160215098) Tejveer Singh (R160215104). 4 schematically shows an electrochemical drilling unit. It is also termed as the “electrolytic grinding” and “anodic machining”. Abrasive Jet Machining. Electrochemical process where an electrolyte is pumped under pressure through the tool to cut a hole through rapid corrosion.
