ABSTRACT:
An electrolytic precision drilling process for making one or more holes in a workpiece, the axis of which hole exhibits an inclination of between 2.degree. to 20.degree. relative to the surface of the workpiece, by means of at least one tubular electrode through which a stream of an electrolyte is directed onto the workpiece, comprising positioning a guide member during the drilling for sealing the gap between the guide member and the surface of the workpiece adjacent to the hole or holes, such that a surface of the guide member forms an angular space with the surface of the workpiece, the aperture angle of the angular space being twice the angle of inclination of the electrode relative to the surface of the workpiece, and the apex of which is in the area of a sharp upper edge of each hole. If one hole is drilled in this manner, the conical angular space is formed. If there are more holes, the angular space is substantially wedge-shaped, and in this case the guide member is preferably prismatic.
