A deflection compensating assembly for deflection sensitive fabricating machine tools such as a press brake. In a press brake, for example, the deflection compensating assembly is mounted between the bed and the lower die or between the ram and the upper die. When mounted on the bed, the deflection compensating assembly, under load, will cause the lower die to become substantially parallel to the upper die. The deflection compensating assembly, under load, will cause the upper die to become substantially parallel to the lower die, when affixed to the ram. The deflection compensating assembly, is preferably a self-contained unit attachable to and detachable from the bed or ram and comprises a variable rate spring, the deflection of which, when under uniformly distributed full length load, is such that, when added to the combined bed and ram deflections, it yields a total deflection which is constant along the length of the bed and ram and will compensate for the bed and ram deflections.
