Together electrochemical chemical deburring refers to a machining process in which burrs are removed using electrochemical energy. A special type of tool is used for this operation which is called a deburring tool. Like any other electrochemical process, in electrochemical deburring also there is no contact between the deburring tool and the ...
Review of Electro Chemical Machining. Electro Chemical Machining ECM is the generic term for a variety of electro chemical processes. ECM is used to machine workpieces through the anodic dissolution of metal. The process is used in aerospace engineering and the automotive, construction, medical equipment, microsystem and power supply industries.

8. Design for electrolyte flow Need for sufficient electrolyte flow between the tool and the workpiece: • To carry away the heat and the products of machining • To assist the machining process at the required feed rate, producing a satisfactory surface finish • Cavitation, stagnation and vortex formation should be avoided since these lead to bad surface finish • …
3. Working Principle • The Electro Chemical Machining works on the principle of Faraday's law of electrolysis. • Faraday's first law of electrolysis- "The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode.

HISTORY The First Introduction Of ECM Was In 1929 By Gusseff, Its Industrial Applications Have Been Extended To Electro-Chemical Drilling, Electro-chemical Deburring, Electro-Chemical Grinding And Electro-Chemical Polishing . The Techniques Was Applied In Several Ways . And As A Machining Technique In The 60's & 70's.
Electrochemical Machining (ECM), characterized as non-traditional machining, is an advanced machining, non-contact, reverse electroplating process (ECM removes material instead of depositing it). In ECM, a high electric current is passed between the tool and workpiece through a conductive fluid.

Chemical machining is a nontraditional machining process that removes metal from a workpiece by immersing it in a chemical solution. The process involves masking areas of the workpiece to be protected, then etching away the exposed material with an acidic or alkaline solution. Chemical machining can produce complex parts with close tolerances ...
Known by many names, the photochemical machining process, a key aspect of chemical machining services, uses a photosensitive polymer called photoresist to produce a highly precise mask that protects the sheet from the etchant.In Elcon's process, our team of engineers digitally image the desired pattern onto the photoresist-coated substrate using solid-state UV LEDs.
Chemical Machining Process Working Principle: The working principle of chemical machining is based on chemical etchant. An etchant is a mixture of strong chemical acids which are reactive to metal. When the workpiece is dipped in the etchant, the etchant reacts with the workpiece causing a uniform rate of dissolution of metal from the workpiece.
