Abstract
An apparatus for grinding two flats of substantially the same dimensions in portions of a conical tip of an element. The apparatus comprises, in combination, a rotatably mounted holding member for holding the element; a rotatably mounted abrasive surface for grinding the tip portion; an index wheel drivingly connected to a flipping lever on the holding member for rotating the element between the two tip portions wherein the point of the tip does not disturb or penetrate the abrasive surface during rotation; and a pivot bearing upon which the holding member is pivotally mounted for contacting the tip portions with the abrasive surface so that a constant force is applied to the tip portion being ground, wherein the tip point does not disturb or penetrate the abrasive surface and wherein the tip remains in contact with the abrasive surface during rotation.
