Claims (1)

[Scope of Claim for Utility Model Registration] (1) In the tool rest of an NC turning machine tool that processes a workpiece by arranging a plurality of rotating tools and fixed tools, the tool rest is indexed in a direction perpendicular to the spindle axis. a turret to which a plurality of tool holders can be attached to an end face perpendicular to the spindle axis; a tool holder for rotary tools in the X direction or Z direction, each of which can be detachably attached to the turret and each rotary tool can be attached thereto; An outer diameter tool that is comprised of a tool holder for an inner diameter fixed tool to which an inner diameter tool can be attached, and an outer diameter fixed tool tool holder that can be detachably attached to the turret and to which an outer diameter tool can be attached, and that is attached to the outer diameter fixed tool tool holder. The shape of each tool holder is regulated so that the mounting position of the cutting edge along the spindle axis direction is fixed slightly closer to the spindle than the maximum protruding end surface on the spindle side of the adjacent tool holder attached to the turret. A turret for a complex NC lathe. (2) Utility model registration claim 1, wherein a tool holder for machining a workpiece gripped by a sub-spindle provided opposite to the spindle axis of the main spindle is removably attached to the mounting surface of the turret. The turret of the compound NC lathe described in Section 1. (3) The mounting position of the tool holder is arranged on the same pitch circumference of the turret, and multiple setting positions of the tool cutting edge position specified in the turret indexing radial direction are provided, and the tool is installed at the setting position that matches the machining conditions. A tool post for a composite NC lathe according to claim 1, wherein the shape of the tool holder is determined so that the holder can be selectively replaced and attached.
