えたＣＮＣ研削盤。[Claims for Utility Model Registration] It has two headstocks, a master axis and a slave axis,
In a CNC grinding machine in which these headstocks grind workpieces by synchronous control using absolute position control, an offset registration means for registering an angle between an offset position of the master axis and an offset position of the slave axis in a state of preparation for operation; difference detecting means for detecting the angular difference between the position of the master axis and the position of the slave axis in a fast rotation state a predetermined number of times at predetermined intervals; and detecting an average value of the angular differences detected by the difference detecting means. A correction value calculation means for calculating a characteristic correction value, and an initial correction of the position of the slave axis based on the difference between the angles registered in the offset registration means, and a dynamic characteristic correction value calculated by the correction value calculation means,
A CNC grinding machine equipped with a position synchronization control device, comprising a correction synchronization control means for additionally correcting the position of the slave axis.
