本文件规定了以下部件的最常见标称尺寸（单位:毫米）: —？形状类型6: 直杯砂轮； —？形状类型11: 锥形杯砂轮； —？形状类型27:用于研磨或研磨/切割的凹陷中心轮； —？形状类型28:凹心砂轮，凹形； —？形状类型29:凹心砂轮，凸形。 这些粘结磨料产品旨在使用手持磨床（角磨机）对工件的任何表面进行去毛刺和整修。在这种应用中，工件是固定的，磨床由操作员引导。 本文件未规定ISO？中给出的极限偏差和跳动公差13942

This document specifies the most common nominal dimensions, in millimetres, of: —？shape type？6: straight cup grinding wheel; —？shape type？11: taper cup grinding wheel; —？shape type？27: depressed centre wheel for grinding or grinding/cutting-off; —？shape type？28: depressed centre grinding wheel, concave shape; —？shape type？29: depressed centre grinding wheel, convex shape. These bonded abrasive products are intended to be used for deburring and fettling/snagging of any surface of a workpiece using hand-held grinding machines (angle grinder). In this application, the workpiece is fixed and the grinding machine is guided by the operator. This document does not specify limit deviations and run-out tolerances, which are given in ISO？13942.
