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 ...
Electrochemical grinding (ECG) at macrolevel and microlevel finds increasing use in medical device manufacturing industry. To enhance application of microECG, a comprehensive study of the role electrolyte flow in the formation of hydroxide layer on a workpiece due to electrochemical dissolution, and its removal due to abrasion by a grinding wheel, and erosion by an electrolyte flow has been ...
Surface analysis studies revealed the presence of oxyhydroxide species of iron on all the sulfide mineral samples which were in prior contact with the grinding medium. The formation of such oxyhydroxide species of iron was found to be dependant on the relative electrochemical activity of the mineral.

Grinding is a subset of cutting, as grinding is a true metalcutting process. Each grain of abrasive functions as a microscopic singlepoint cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
