A series of grinding steps follows whereby each new step makes use of even finer grinding medium to proceed step-by-step towards the grade of polished surface desired. The sample has to be rotated through 90° after each grinding step in order to cancel out the grooves left over from contact with the previous grinding medium.

Metal bonded diamond grinding wheels are widely used in the grinding process especial in ELID grinding. However truing is difficult owing to the high toughness of metal bond materials and high hardness of diamond abrasives. To realize high precision and high-efficiency truing we propose a new micro-truing method consisting of electro-discharge truing and electrolysis-assisted mechanical
