Abstract
A turret ( ) is clamped to a tool rest main body ( ) by a pair of coupling members ( ). During indexing rotation for selecting a tool, the tool rest main body ( ) and the turret ( ) are moved relatively in a Z-axis direction, and the pair of coupling members ( ) are unclamped. At this time, the tool rest main body ( ) is moved in the Z-axis direction relative to a lathe main body ( ) in synchronization with the relative movement in the Z-axis direction between the tool rest main body ( ) and the turret ( ). This movement of the tool rest main body ( ) is adjusted in direction and moving distance so that the relative movement between the turret ( ) and a spindle table ( ) is eliminated. As a result of this movement control, the turret ( ) and the tool fitted to the former do not have relative displacement to the spindle table ( ) and to a work, so that the danger of mutual interference among these constituent elements and the work can be eliminated.
