Workpiece insertion and removal process in double end surface grinding and a double end surface grinding machine

摘要

It is the object of the invention to prevent a workpiece from falling down in a carrier at the time of inserting and discharging the workpiece, which makes it possible in advance to prevent damage to the workpiece. To do so, in double end surface grinding for grinding both surfaces of the workpiece W by a pair of grinding wheels while rotating a thin sheet-like workpiece W held by a pair of static pressure pads 1 and 2 by a support 7 at the time of Sucking of the workpiece W by the introducing and Ausbringmittel 8 and 9 to carry the workpiece W between the two static pressure pads 1 and 2 in the carrier 7 and out of this carrier after the workpiece W from the introduction and Ausbringmittel 8 and 9 and the right static pressure pad 2 has been clamped, in this state, the workpiece W in the carrier 7 is sucked by the right static pressure pad 2 at an advanced stop position X1.
