A machine for punching or pressing sheet material comprises a support base, a stationary machine member and a machine member which is rectilinearly displaceable relative thereto for the working movement. At least one such member is fitted with a tool and in order to produce the working movement, a wedge is displaceable transversely to the direction of the said movement in a reciprocatory manner by means of a drive provided between the base support, or a member connected thereto, and the displaceable machine member, or a member connected thereto. The load transmitting surfaces on the wedge and the load transmitting surfaces facing the same on the adjacent support base and displaceable member are formed by hardened body-surfaces.
