Spindle interference prevention system for opposed two-spindle lathes. 2. In a numerically controlled lathe that has two opposing spindles and a mechanism for sending those spindles in the direction of the center axis, the target positions of the two spindles are calculated from the program command value, the spindle origin offset, and the tool offset information. , the distance between the spindles is determined from the information on the calculated target position, and the distance between the spindles is compared with a preset allowable distance to monitor mutual interference before moving the two spindles. This is a spindle interference prevention method for an opposed two-spindle lathe.
