Abstract (en)
[origin: US6206766B1] The invention relates to a grinding wheel for machining metal circular-saw blades at relatively high rotational speeds, which have machining areas which contain in particular hard materials, such as for example diamond or cubic boron nitride. The grinding wheels according to the invention are intended in particular to improve the centring at relatively high rotational speeds, and consequently to prevent true running problems as far as possible. The base body of the grinding wheel is of contoured design, at least on one side, in the radially outer area of a tool-mounting bore, and at least one centring element can be designed to engage in a formfitting manner in the correspondingly designed contours, so that the grinding wheel and a centring element on a tool spindle of a grinding machine are held together in a force-fitting manner.
