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41:平切轮； —？形状类型42:下压中心切断轮。 这些粘合磨料产品用于切割使用手动或机械引导的固定或移动切割机切割任何工件。在手动引导的应用中，工件通过自身重量牢牢夹紧或稳定。切割离轮由操作员引导，工件固定，反之亦然。 本文件未规定极限偏差和运行ISO中给出了哪些公差13942

This document specifies the most common nominal dimensions, in millimetres, of: —？shape type？41: flat cutting-off wheel; —？shape type？42: depressed centre cutting-off wheel. These bonded abrasive products are intended to be used for cutting？off of any workpiece using stationary or mobile cutting-off machines, both manually and mechanically guided. In the application that is manually guided, the workpiece is firmly clamped or stabilized by its own weight. The cutting？off wheel is guided by the operator and the workpiece is fixed, or vice versa. This document does not specify limit deviations and run？out tolerances, which are given in ISO？13942.
