Machine Tool Drive System

摘要

A drive system for a machine tool comprises two, at least equally long drive spindles, extending parallel to each other and being structurally identical with regard to their torsional rigidity and their axial rigidity, which are each supported to rotate about a spindle axis, and which can be driven about the spindle axis concerned. Each of the drive spindles has a fixed bearing at one end, acting in its longitudinal direction. Spindle nuts, which are seated on the drive spindles can be moved simultaneously with longitudinal movements in the longitudinal direction of the drive spindles.

1. A machine tool drive system comprising:
a spindle arrangement that has at least one drive spindle; and two spindle nuts, the spindle arrangement comprising two drive spindles extending parallel to each other along a longitudinal direction, each drive spindle supported for rotation about a respective spindle axis and configured to be driven about the respective spindle axis, the two drive spindles being of identical torsional and axial rigidity and each having a fixed bearing at one end, acting in the longitudinal direction of the respective drive spindle; and the two spindle nuts configured to be moved by the spindle arrangement simultaneously with longitudinal movements in the longitudinal direction of the drive spindles, each of the spindle nuts seated on an associated one of the two drive spindles; wherein the spindle nuts are moveable by the spindle arrangement, in the longitudinal direction of the drive spindles, by each of the spindle nuts being movable by the associated drive spindle.
