The operator finds that the demagnetization time is difficult to master, which makes the demagnetization effect not good. To this end, we have made some improvements to the demagnetization line as follows. The electrical part of the original machine tool is shown in Figure 1. During processing, the switch SA is turned to the processing position, so that 23 and 24, 22 and 26 are turned on, and the DC power source flows through the electromagnetic chuck coil YH, at which time the workpiece is sucked.
