Abstract
Segmental grinding wheel for forming the tip of intersecting surfaces on tools includes an array of peripherally extending and circumferentially, spaced segments. Each segment includes first and second grit-coated angularly oriented grinding surfaces. Another array includes similar grinding segments which are interdigitated in alternating sequence with the segments of the first array. The segments of the two arrays are concentric and partially coextensive in the axial direction of the wheel so that the plane of rotation of the first grinding surface of each segment in one array intersects the plane of rotation of the second grinding surface of an adjacent segment in the other array along a line which represents the tip of the intersecting surfaces.
Claims2
A segmental rotary grinding wheel for forming saw teeth on the edge of a blade comprising at least one array of circumferentially-spaced grinding segments having first and second angularly oriented grinding surfaces, at least one other array of such grinding segments disposed in partially coextensive and fixed axial relationship with the angularly oriented grinding surfaces of adacent segments of the two arrays defining the configuration of a saw tooth, the first and second grinding surface of the segments, in each array, having generally the same surface area as the corresponding surface of the other segments in that array, each of said arrays of grinding segments extending from the periphery of a circular disc with the discs being disposed in abutting coaxial relation and the grinding segments of one disc interdigitated between the segments of the other disc.
