A power turret device includes a turret set on which processing tools are disposed, a transmission gear set disposed in the turret set, an inner axle penetrating through the turret set, a clutch set disposed on the turret set and including first and second engagement units, and a driving set. The turret set includes a base and a turret portion having a head and a support shaft integrated with the head. The integration of the head and the support shaft facilitates the replacement of the turret portion and distributes the weight of the turret portion evenly to prevent undue wear. The turret portion rotates to move any selected processing tool to a proper processing position when the engagement units are separated. The engagement between the engagement units allows the selected processing tool to rotate on its axis. The processing accuracy is increased and the service life is prolonged.

A laser tube cutting machine for the cutting processing of tubes with a workpiece moving device, which receives the tube and moves it relative to a push-through device supporting the tube, which is guided by clamping jaws of the push-through device. A laser machining device is associated with the push-through device and has a processing head which directs a laser beam emerging from the processing head onto the tube. A tool of a processing device mechanical processes the tube, which tool is moveable in at least one direction of movement relative to the tube. At least one counterholder is movable into a working position for abutting against the tube, which counterholder acts in the opposite direction to the direction of application of force of the tool.

A broaching machine may include a broaching tool and a moving mechanism. The broaching tool may be movably arranged in a spindle of a lathe in a horizontal direction to machine a workpiece fixed to a chucking mechanism of the lathe. The moving mechanism may move the broaching tool in the horizontal direction. Thus, a process for forming a hole through the workpiece using the lathe and a process for machining the inner surface of the hole using the broaching machine may be continuously performed so that a time for machining the workpiece may be remarkably reduced. Further, the process for forming the hole through the workpiece using the lathe and the process for machining the inner surface of the hole using the broaching machine may be continuously performed on the workpiece fixed to the chucking mechanism to suppress dimension failures of the workpiece.

A machine tool for the machining of elongate workpieces includes a workpiece support column having workpiece support components for supporting a first workpiece and second workpiece support components for supporting a second workpiece. The first workpiece support component and the second workpiece support component are arranged for supporting the first workpiece vertically above the second workpiece. The workpiece support column is rotatable around a vertical axis so as to shift the workpieces between the machining station and a station for loading and unloading of workpieces. The workpiece support component include a drive element for applying torque to the workpieces for machining of the workpieces by turning. A motor and chuck assembly and a method of machining workpieces are related.
