随着机械工业科学技术的发展,精密机床的精度越来越高,单位以微米计。因此,几何精度测量方法和测量精度问题,在精密机床修理中占有突出的地位,其中,几何精度检查中,有工作台纵横向移动的不垂直度检查项目,是关键项目之一。往常用精密角尺的检查方法亦不适应精密机床的要求。本文介绍一种既简单便捷,测量精度又高的检查方法,基本上解 With the development of mechanical industry science and technology, the accuracy of precision machine tools is getting higher and higher, the unit is micrometer. Therefore, the measurement method of geometric accuracy and the problem of measurement precision occupy a prominent position in the precision machine tool repair. Among them, in the check of geometrical accuracy, there is a non-perpendicularity inspection item for vertical and horizontal movement of the workbench, which is one of the key items. Inspection methods commonly used precision square also do not meet the requirements of precision machine tools. This article describes a simple and convenient, high accuracy and high inspection methods, basically solution
