机床几何精度检验包括零部件或运动的直线度、平面度、平行度、等距度、重合度、垂直度以及旋转精度等的检验。在本讲中介绍这些精度项目的常用检验方法,所用的主要量检具是水平仪、指示表、读数显微镜、平尺、90°角尺及检验棒等。对广大企业(包括乡镇企业)的设备维修部门都有条件应用。 Geometric accuracy test machine parts, including linear or flatness, flatness, parallelism, equidistance, coincidence, perpendicularity and rotation accuracy of the test. The common test methods for these precision items are introduced in this talk. The main gages used are level gauges, indicator gauges, reading microscopes, flat rulers, 90 ° angle rulers and test bars. The majority of enterprises (including township enterprises) equipment maintenance departments are conditional application.
