The process continues until the two clamping plates stably hold the cylinder. Then, the electric cylinder is activated to move the vertical plate, causing the electric push rod and grinding disc, fixed at one end of the rotating rod, to move inside the cylinder. The electric push rod is then activated to move the grinding disc to the appropriate grinding position.
