Abstract

A linear guide, in particular for a device for electrochemical metal machining, that guides a linear movement of a quill that is moved periodically in a machine frame in order to periodically modify a working gap between a cathode situated on the quill and a workpiece in the direction of the longitudinal axis of the quill, the quill being connected to the machine frame by a plurality of connecting rods, the connecting rods being situated, in the no-load, non-deflected state, essentially parallel to the longitudinal axis of the quill, and the connecting rods having at the point of connection to the quill, as well as at the point of connection to the machine frame, a notch hinge in order to enable, via the hinge, the periodic linear movement of the quill, and the flexibilities of these notch hinges being based on elasticities in their structures formed by targeted thinning of the material.
