Abstract: A tool spindle having a spindle shaft rotationally-drivable about a spindle axis, a clamping system for the automatic chucking and unchucking of a tool, wherein the clamping system comprises a movement device enabling at least one movable and/or deformable clamping body of the clamping system to be transferred from a first position into a second position by execution of a movement of a part of the movement device in relation to the spindle shaft, wherein the tool is chucked on the tool spindle in the first position and the tool can be removed from the tool spindle in the second position, wherein it comprises a balancing system, which is integrated into the tool spindle so that it rotates jointly with the rotationally-drivable spindle shaft, which is arranged coaxially in relation to the spindle axis, and which is mounted so it is axially movable.

Abstract: The invention relates to a device for green machining bevel gears, comprising an CNC machining station for gear cutting a wheel blank (K2). The machining station comprises a tool spindle which is used to receive a gear cutting tool and a work piece spindle which is used to receive the gear blank (K2). Said machining station also relates to a machining station which operates in a vertical manner. Said device also comprises a vertical processing station having a tool holder and a work piece spindle which is used to receive a work piece blank (K1). The machining station mechanically forms a functional unit together with the pre-machining station, wherein the work piece blank (K1) undergoes green machining in the pre-machining station, and is transferred as a gear blank (K2) to the first machining station after the first green machining where it is cut into a gear. Said machining station and the pre-machining station are linked together in terms of data and control.
