Figure 2 shows the idea of the present method which was proposed in the previous paper [] and originally named as wire electrochemical grinding (WECG) after the well-established wire electro-discharge grinding (WEDG) method [].However, the naming is changed to wire electrochemical turning (WECT) in this paper because turning is more appropriate to …

Even though these materials are highly required in the field of the modern industries. To overcome the problem, a new machining method has been proposed by researchers by combining the features of electro-chemical machining and electro-discharge machining. Such combined machining process is called as electro-chemical spark machining …

Electrochemical grinding is often used for hard materials where conventional machining is difficult and time-consuming, such as stainless steel and some exotic metals. For materials with hardness greater than 65 HRC, ECG can have a material removal rate 10 times that of conventional machining.

Like ECM, Electrochemical Grinding (ECG) generates little or no heat that can distort delicate components. Electrochemical Grinding (ECG) can process any conductive material that is electrochemically reactive. The most common reason customers choose ELECTROCHEMICAL GRINDING (ECG) is for the burr free quality of the cut.

Method # 2. Electro-Chemical Grinding (ECG): Based on electro-chemical machining process and refinement to it, the process of electrolytic grinding has been developed in which metal is removed both by electro-chemical decomposition (about 90%) and abrasion of the metal (about 10%). Thus the wheel wear is very less.

Very fine features can be machined by this method including small diameter holes, die cavities, etc. The discharge rate is not generally affected by hardness but by the thermal properties and conductivity of the metal. Electro-Chemical Machining is something of a reverse electroplating process and produces burr-free holes with high surface ...

A consumable electrode itself melts down during welding and subsequently deposits on the weld bead. A non-consumable electrode does not melt down or deposit on the weld bead. It remains intact throughout the welding. A consumable electrode acts as filler and thus it supplies necessary filler material intended to fill the root gap.

Chemical machining for some special purposes can also be achieved by using a jet of reactive gas, e.g., chlorine on the machining zone. This is known as Gaseous Chemical Machining or Hot Chlorine Machining and can be used for deburring of metal parts. Chemical Milling. Chemical milling sometimes called Chem milling or contour machining or etching.

New Applications for Electrochemical Grinding. With advances in control, sensor and automation technology, electrochemical grinding is more accurate and productive than ever, opening up new applications for the traditionally niche process.

No corrosive etchant is used here; instead, a suitable electrolyte is employed. ECM requires a shaped tool made of electrically conductive material that is placed close to the workpiece (a small gap is maintained). Both tool and workpiece are connected with two polarities of a DC power source and are immersed partially into the electrolyte.

First of all, we will take a brief glance at the term, "electrochemical honing". Basically, it is a material removal process in which electrical energy, chemical energy and honing are used.
