PCT No. PCT/EP82/00212 Sec. 371 Date May 20, 1983 Sec. 102(e) Date May 20, 1983 PCT Filed Sep. 22, 1982 PCT Pub. No. WO83/01030 PCT Pub. Date Mar. 31, 1983.The invention relates to an overload protection device for a machine tool, in which a carriage carried on the machine bed is displaceable, between the tailstock and the headstock by a lead screw [driven] by a drive motor and a feed gearing, and in which the lead screw nut is joined to the carriage by at least one joining bolt. To permit a very quick restoration of the machine to service after a collision between the carriage and a component present in its path of movement, while the predetermined dimensional relationship is restored without additional readjustment, the overload protection device is constructed such that the joining bolt has a break-away section in the area of the junction between the carriage and the lead screw nut.
