Abstract: A device for the cutting metal-machining of one of several workpieces clamped on pallets (WP) and held ready in a device for holding several such pallets (WP) with a control device for timed sequence control, the conveyance of the preselected pallet (WP) bearing a workpiece from the preparation (18) to the machining position (BP), a tool spindle unit changing device for preparing a preselected tool spindle unit (10) in its operative position (AP), a tool changing unit (14, 31) to prepare and take the preselected drilling, milling or grinding tool (WZ) from a tool magazine (14) into the sleeve (13) of the tool spindle unit (10) and a device in the form of a pallet magazine (PM) to take at least two workpiece pallets (WP) which has at least one preparation position (18) arranged in the vertical plane and in which the clamping position (17) is horizontal, and a conveyor (ZU) for bringing at least one loaded pallet (WP) from the preparation (18) to the machining position (BP) of the workpiece carrier (WT) having

Abstract: Device for metal cutting a workpiece in a clamping fixture by using tools (WZ) which are removable in alternating sequence from a tool magazine with a sequence control of the machining steps and with a tool spindle unit changing device (4) and with a tool changing device comprised of a movable and rotatable as well as pivotable tongs-type grasp (ZG), the grab jaws (28, 29) of which being aligned to the respective tool removal axis and spindle axis (Z), and a mirror-image jaw profile (30) to receive tools (WZ) with more than two different shank or taper sizes with at least three adjoining arched sections (a, b, d), the radii (ERa, ERb, ERd) of which match the different diameters of at least three shank or taper sizes, and in which the tool spindle unit (10) which is in the working position is insertable into and removable from a receptacle and exchanged for a tool spindle unit (11) in a stand-by position.
