Abstract
The invention discloses a three-stage upper plate rising and falling speed control method for a plane grinding machine. The three-stage upper plate rising and falling speed control method includes the rising process and the falling process. By means of the three-stage upper plate rising and falling control mode, the large speed is used when falling begins and is gradually decreased; the quite slow speed is used when an upper plate approaches a workpiece, the unbalanced pressure on the workpiece is reduced, and the yield is increased; and the rising process is the inverse process of the falling process. By means of the method, the risk that the workpiece is damaged is effectively avoided.
