Title:
自動旋盤及びその制御方法
Document Type and Number:
Japanese Patent JP4067134
Kind Code:
B2
Abstract:
A turret (11) is clamped to a tool rest main body (10) by a pair of coupling members (27). During indexing rotation for selecting a tool, the tool rest main body (10) and the turret (11) are moved relatively in a z-axis direction, the pair of the coupling members (27) are unclamped. At this time, the tool rest main body (10) is moved in the z-axis direction relative to a lathe main body (100) in synchronism with the relative movement in the z-axis direction between the tool rest main body (10) and the turret (11). This movement of the tool rest main body (10) is adjusted in direction and moving distance so that the relative movement between the turret (11) and a main spindle table (1) is eliminated. As a result of this movement control, the turret (11) and the tool fitted to the former do not have relative displacement to the main spindle table (1) and to a work, so that the danger of mutual interference among these constituent elements and the work can be eliminated.
