よって作動される。Conventionally, the spindle head had vertical and horizontal spindles, respectively, and the spindle head rotated and positioned the vertical axis.
When machining the side surface of a workpiece using a double-mounted portal type machining center, the horizontal spindle is indexed to the machining surface, so if the positioning accuracy is poor, the original , which affects machining accuracy. In addition, this type of machine is structured so that even when one spindle is machining, the other spindle also rotates. It is impossible to change the tool to the other spindle when changing the tool, leading to an idle period during the tool change, which tends to increase the cycle time, which is undesirable.The present invention aims to solve the following two drawbacks. The present invention will be described below based on embodiments. First, in explaining the configuration of the main spindle control device of the machining center of the present invention, a schematic diagram of the configuration of a machining center suitable for achieving the object of the present invention is shown in FIG. An explanation will be given based on an example.
