Patent ID: 7621030

Claim:
A multi-spindle machining center for the chip forming processing of workpieces comprising a spindle group having at least one spindle row including at least two spindles with longitudinal axes arranged in the at least one spindle row 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, which at its longitudinal terminal regions is movably held on a respective workpiece support bearing means and the spindles are guided for a movement toward the workpiece support in a first axial direction, which is the direction of the longitudinal spindle axes, on a spindle linear guide arrangement that extends through a portal frame, wherein for positioning the workpieces within a working region of the spindles, the workpiece support bearing means comprises, at the longitudinal terminal regions of the longitudinal support member a respective linear guide means, which is guided on a workpiece support linear guide arrangement in a second axial direction athwart the first axial direction, and wherein in the first axial direction, when the spindle group is located inside the portal frame, the workpiece support linear guide arrangement is located closer to the spindle group than the workpiece support is.
