Electro Chemical Grinding (ECG) Electrochemical grinding combines both electrolytic action (90%) and physical grinding (10%) to provide precision, burr-free and stress-free results.
Although there are many ways to cut metal, only Electrochemical Machining provides the possibility of a completely burr free result. When burr free machining is required, Electrochemical Grinding is often the most cost effective choice.

An investigation is reported on electrochemical grinding (ECG) of WC-Co cemented carbides, with particular consideration of their heterogeneity. An analysis of the electro-chemical removal process for these materials indicates that electrochemical dissolution into the cobalt phase occurs initially at a much faster rate than into the carbide phase.
An electrochemical grinding wheel of substantially uniform conductivity along its contoured grinding surfaces is modified to reduce the conductivity at locations generally parallel to the tool-feed direction (perpendicular to the machine surface) so that electrochemical removal of material from the workpiece occurs substantially only at those surfaces which are transverse to the tool-feed ...

At titanium alloy grinding within the initial period of machining (after 3 min) the wear in mechanical grinding (MG WT3-1) is about six times greater than in electrochemical grinding (AECG WT3-1), and within the terminal period of measurements (after 21 min) about five times greater.
Gearing up to grind aluminum Discs and tips. Practical Welding Today March/April 2011 March 14, 2011 By: Patrick Carroll Aluminum is a difficult material to process as it poses a unique set of challenges, particularly when it comes to grinding.
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.
Nadcap Nonconventional Machining Training Courses We have training courses for each Nadcap Nonconventional Machining standard (Nonconventional Machining, Electrochemical Machining, Electrochemical Grinding, Electrical Discharge Machining, Laser Beam Machining, Laser Part Marking, Spark Erosion Grinding).
Abrasive grinding is an ideal alternative to conventional machining because of the high ductility and rapid work hardening of the material. Electrochemical grinding (ECG) combines the precision of abrasive grinding with the low force qualities of electrochemical erosion.The process limits physical stresses, mechanical damage, and heat affect inherent to more conventional processes.
Give brief information about electro-chemical machining process ... grinding and electrochemical polishing The technique was applied in several ways as a machining technique in the 60's and 70's.
Electrochemical grinding (ECG) - Prof. SAVAN FEFAR Electrochemical grinding (ECG) Prof. SAVAN FEFAR 2. • The process is similar to cathode is a specially constructed grinding wheel instead of a cathodic shaped • The insulating abrasive material (diamond or aluminum oxide) of the grinding wheel is set in a conductive bonding • the wheel is ...
A honing stone is similar to a grinding wheel in many ways, but honing stones are usually more friable so that they conform to the shape of the workpiece as they wear in. To counteract their friability, honing stones may be treated with wax or sulfur to improve life; wax …
Electrochemical machining (ECM). is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).
