The diameter of a sleeve or an adaptive flange shall be calculated according to the following formula:Df ≧ K (D-H) + HWhere: Df, D, H, and K are as follows:Df: diameter of the fixed- flange (millimeters)D: diameter of the grinding wheel (millimeters)H: inner diameter of the grinding wheel (millimeters)K: constant according to the rules in attachment table 23.The contact width in the preceding paragraph shall be in accordance with the diameter of the grinding wheel and not less than that given in attached table 24.The adapting flange shall not be set on the grinding wheel with a usable velocity higher than a normal velocity.Attachment table 23.pdfAttachment table 23.docAttachment table 24.pdfAttachment table 24.doc
