Electrochemical grinding - Wikipedia

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 of the workpiece. What is Electrochemical Grinding and How it Works,,Chemical Grinding . MPE grinding equipment is corrosion-resistant to handle even the most corrosive chemical applications. Our grinders are also unmatched in their efficiency and reliability, allowing your chemical grinding operations to keep going all-day, all-year without a hiccup.Grinding (abrasive cutting) - Wikipedia,The workpiece is manually clamped to a lathe dog, powered by the faceplate, that holds the piece in between two centers and rotates the piece. The piece and the grinding wheel rotate in opposite directions and small bits of the piece are removed as it passes along the grinding wheel. In some instances special drive centers may be used to allow the edges to be ground. The workholding method affects the production time as it changes set up times.
