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持式电动工具（如角磨机和直磨机）将任何工件磨掉。在此应用中，工件是固定的，手持电动工具由操作员引导。 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 hand-held power tools (e.g. angle grinders and straight grinders). In this application, the workpiece is fixed and the hand-held power tool is guided by the operator. This document does not specify limit deviations and run？out tolerances, which are given in ISO？13942.
