Abstract
A machine tool comprises a frame; a work holder operably associated with the frame; at least one carriage disposed on the frame and movable along an axis; at least one tool disposed on the carriage for operating on a work piece disposed in the work holder; at least one nozzle assembly disposed on the carriage for directing at least one fluid stream to the work piece and the tool; a screw-nut drive operably associated with the carriage, the drive including a lead screw; a device for stretching the lead screw for compensating for thermal growth of the screw during operation; and a resilient strip operably disposed between the frame and the carriage for absorbing impact forces.
