Schleifscheibe fuer Hochgeschwindigkeitsschleifen

The grinding wheel (1) for high-speed grinding consists of a base composed of a connecting flange (2) and a disk (3) having a coated form-grinding body (4) which bears a galvanically bonded grinding coating (5). Attachment is provided by the flange (2) and the boreholes (6) arranged in a circle located centrally to the axis of rotation (7). The profile of the disk (3) has a shape which is tapered in the radial direction by a defined change in width related to a low diffusion of stress and minimum elongation. The width (b) of the disk is tapered in the shape of a curve in the radial direction. The progression (K) of of the disk width in the radial direction can be calculated by computer using an iteration process by subdividing the profile of the disk in any number of small rings of different widths starting with a simplified shape. The progression of the tension and elongation are calculated and the width of the rings is changed step by step with such frequency as to obtain the lowest possible tension and elongation.
