Abstract:
1. A linear guide for a device for electrochemical metal machining, that guides a linear movement of a quill that is moved periodically in a machine frame 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 guide comprising: at least two connecting rods connecting the quill to the machine frame, the connecting rods being situated, in the no-load, non-deflected state, essentially parallel to each other and transverse 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, notch hinges for enabling periodic linear movement of the quill with reduced wear on the linear guide, and the flexibilities of these notch hinges being based on elasticities in their structures formed by targeted thinning of the material; and a coupler being parallel to the longitudinal axis of the quill and connected to the quill, and connecting ends of said at least two connecting rods for conveying movements of the quill to said at least two connecting rods.
