Patent ID: 7621029

Claim:
A multi-spindle machining center for the chip forming processing of workpieces comprising a spindle group having at least two spindles arranged in a spindle row adjacent to each other to mount a chip forming tool, and a workpiece support, on which at least two workpiece holders, correlated with the geometrical arrangement of the spindles, for holding workpieces for a simultaneous processing by means of the spindles, are arranged, the workpiece support having a beam-like longitudinal support member bearing the workpiece holders, and the spindles are guided for a movement toward the workpiece support in a first axial direction on a spindle linear guide arrangement, wherein for positioning the workpieces in relation to the spindles, the workpiece support is guided on a workpiece support linear guide arrangement in a second axial direction running athwart the first axial direction and wherein the workpiece support is able to be shifted on the workpiece support linear guide arrangement to a servicing area arranged above a working region of the spindles, wherein the workpiece support linear guide arrangement includes workpiece support linear guides, each arranged on a guide column of a portal, and wherein located above the portal is a workpiece changer for exchanging a workpiece from the workpiece support when the workpiece support is in the servicing area.
