。Conventional turret heads are used for indexing the rotary tool post and for tools (
Since the rotation of the main shaft (main shaft) is performed by separate drive systems, a dedicated drive motor is required for each. Furthermore, since the drive system for the main shaft is one system, only one type of tool can be attached to one indexing surface of the rotary tool post even in a multi-spindle type. That is, it is not possible to attach a drill and a tap or a reamer and a tap to one indexing surface, and only the drill can be attached to a drill, and only the tap can be attached to a tap. Therefore, when drilling and threading a workpiece, two types of processing machines are required.
