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. ==Process characteristics== * The wheels and workpiece are electrically conductive. * Wheels used last for many grindings - typically 90% of the metal is removed by electrolysis and 10% from the abrasive grinding wheel. * Capable of producing smooth edges without the burrs caused by mechanical grinding.〔Valenti, Michael, "Making the Cut," Mechanical Engineering, American Society of Mechanical Engineers, 2001. http://www.memagazine.org/backissues/membersonly/nov01/features/makcut/makcut.html, accessed 2/23/2010〕 * Does not produce appreciable heat that would distort workpiece.〔Valenti, "Making the Cut."〕 * Decomposes the workpiece and deposits them into the electrolyte solution. The most common electrolytes are sodium chloride and sodium nitrate at concentrations of 2 lbs per gallon.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electrochemical grinding」の詳細全文を読む スポンサード リンク
