高精度主轴部件是精密机械和精密仪器的关键部件。主轴回转精度是主轴部件的主要技术指标之一。欲提高主轴部件的制造精度,就必须解决精密主轴回转精度和有关零件精度的测量。主轴回转精度的测量,一般采用标准球安装在工作台上打表读数,或者用高精度测微仪、接触干涉仪、自准直光管等静态测量,读数记录再作数据处理。这类方法存在两个问 High-precision spindle components are the key components of precision machinery and precision instruments. Spindle rotation accuracy is one of the main technical specifications of the spindle components. To improve the manufacturing precision of the spindle components, it is necessary to solve the precision spindle rotation accuracy and related parts accuracy measurement. Spindle rotation accuracy measurement, the general standard ball mounted on the table playing watch readings, or with high precision micrometer, contact interferometer, self-collimating light tube and other static measurements, reading records for data processing. There are two questions to this approach
