A cutting table that moves to adjust the amount of dimensional change during grinding, a sizing detector that measures the amount of dimensional change of the workpiece, and an excitation current of the electromagnet that adjusts the excitation current to keep the rotor axis floating at a reference target position. and a control means for controlling the movement of the cutting table, and when it is detected by the detection output of the fixed size detector that the dimension value of the workpiece has reached a predetermined value, the grindstone is separated from the workpiece. In a control device for a grinding machine that controls the cutting table to move backward in a direction, the control means is configured to control the levitation of the reference of the rotor shaft when it is detected that the dimension value of the workpiece has reached a predetermined value. A control device for a grinding machine, characterized in that a target position changing means is provided for changing the target position in a backward direction of the cutting table.
