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.
In a machine tool having a machine bed, a carriage carried on said machine bed, a lead screw for reciprocating said carriage on said machine bed, a flange and a lead screw nut connected to the flange and connecting said lead screw to said carriage;
