Aim of the presentation Give brief information about electro- chemical machining process Show the ECM's working principles and tools Define the advantages and disadvantages Brief informations about application areas, economics, products and developments.
Because the tool electrode used in the process does not wear, soft metals can be used as tools to form shapes on harder workpieces. Other applications include deburring, hole drilling, electrochemical grinding, and removal of fatigue cracks in steel structures. The working principles of ECM are described along with the types of electrolytes used.
Electrochemical machining is a process of a selective dissolution of the anodically connected work piece material submerged in an electrolyte together with an anodically connected tool. Principally electrochemical machining is similar to Electropolishing where the work piece surface roughness decreases due to the conversion of the atoms into ions and their removal from the surface as a result ...

3. Classification of ECM Process 3.1. Electrochemical Grinding Process In the electrochemical grinding process metal is removed by electrochemical decomposition and abrasion of the metal. In this process electrode wheel revolved in the close proximity to the workpiece. Wheel is made of fine diamond particles in metal matrix.
2.Electrochemical Grinding (ECG) 1.In ECG, the material removal is achieved by combined action of abrasive and electrochemical process energy. The resulting surface has high surface integrity, is burr free, and has negligible distortion. 2.The abrasive particles of the grinding wheel make a contact with the workpiece and the gap between the
ELECTROCHEMICAL MACHINING. Introduction . Electrochemical machining (ECM) is a metal-removal process based on the principle of reverse electroplating. In this process, particles travel from the anodic material (workpiece) toward the cathodic material (machining tool). .
– Process parameters: abrasive type, grit size, & flow rate – Other parameters: Nozzle office diameter(0.25 to 0.63 mm) ... Electrochemical Grinding (ECG) Special form of ECM in which a grinding wheel with conductive bond material is used to augment anodic dissolution of metal part surface
Sep 24, 2018· 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".
The electrochemical grinding process employs the principle of electrolytic anode dissolution, see Ref. [1]. The grinding machine used is similar to a conventional grinding machine, the main difference being that the grinding wheel and spindle are insulated electrically from the rest of the machine, Fig. 1.
Jun 10, 2017· Electrochemical machining (ECM) is a non-traditional 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.
basis for electrochemical machining of metals. A schematic of the conventional ECM process is presented in Fig. 1. ECM process uses an electrolyte that completes the electric circuitry between anodic workpiece and cathodic tool and prevents the anodic material from being deposited on cathode. Thus, it is reverse process of electro-plating.
mathematical modeling of an abrasive electrochemical grinding (AECG) process. In AECG a metal-bonded grinding wheel is used instead of a graphite or metal wheel-electrode used in electrochemical grinding (ECG). Therefore, the mechanical abrasion is combined with the electrochemical dissolution.
electrochemical machine. In addition, a detailed description of the process principle, applications and some guidelines for future research have been tinted. Key words: electrochemical honing, design, equipments, process control, functional surfaces, surface finish, geometrical accuracy.
This research investigates the process of electrochemical grinding (ECG) when used to machine metal-bonded diamond composite wheels. These wheels are used as form tools to grind ceramics.
Grinding of surgical needles, other thin wall tubes, and fragile parts •Advantages: Deplating responsible for 95% of metal removal, and abrasive action removes remaining 5% Because machining is mostly by electrochemical action, grinding wheel lasts much longer Result: much higher grinding ratio, less frequent dressing
