A machine tool comprises two motion units, in particular a spindle stock and a machine bed, arranged for being displaced relative to each other along one axis. A guideway is fixed to a first motion unit for guiding the displaceable motion unit, a first surface of the guideway being in contact with, and screwed to a second surface of the first motion unit. In order to prevent the guideways from being dislodged in a direction perpendicular to the longitudinal axis of the machine screws, for example when the spindle stock runs up against a stationary obstacle due to improper operation, at least one of the said surface is roughened. |
