Discharge Grinding Electrochemical

Electrochemical machining Wikipedia

Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials.

Electrochemical grinding Wikipedia

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

Electrical Discharge Machining (EDM) and Grinding (EDG

A workpiece made of electrically conductive material and a shaped tool are immersed in a dielectric fluid. XMSH pulses of electricity pass through the tool (+ve electrode) and the negatively charged workpiece, leading to a spark discharge. Plasma forms and, along with the sparks, vaporises the workpiece material removing material ‘chips’, which are then flushed away by dielectric fluid.

Difference Between EDM and ECM Electro-Discharge

Electro-Discharge Machining (EDM) is one thermal energy based process where material is removed by localized melting and vaporization. Intense heat is generated by means of electric sparks. Here the tool made of conductive material is made one electrode (negative polarity), while the conductive workpiece is made another electrode (positive polarity); and a small gap is maintained between the
