Abstract
Support and guiding means for a wire electrode in an electro-erosion machining apparatus comprising a V-block support and guide having two angularly disposed guiding surfaces substantially parallel to the wire electrode longitudinal axis mounted on a base automatically orientable radially about the wire longitudinal axis such that the axis of a linear cut through the workpiece or, alternatively, the tangent of a curvilinear cut substantially bisects the angle formed by the two angularly disposed guiding surfaces.
Claims7
In an electro-erosion machining apparatus comprising a wire electrode stretched and axially translated between a pair of spaced apart wire guiding means and means for displacing the portion of said wire stretched between said guiding means relative to a workpiece to effectuate a cut through said workpiece according to a programmed path, the improvement for at least one of said guiding means comprising a pair of angularly disposed guide surfaces substantially parallel to the longitudinal axis of said wire electrode, means urging said wire electrode in engagement with said guide surfaces, support means for said guide surfaces, and means for rotating said support means about an axis substantially corresponding to the longitudinal axis of said wire electrode as a function of the direction of said path such that the areas of the wire electrode in engagement with said guide surfaces correspond to areas of the wire electrode which are not affected by electro-erosion wear.
