一台机床的主轴精度取决于轴颈圆度误差的大小。它直接影响主轴的旋转精度,引起定位误差、旋转噪音和降低使用寿命。因此,提高主轴轴颈圆度精度,设法在生产现场进行测量即成为一个迫切问题。 目前在圆度测量方面通常采用圆度仪测量法和V形测量法。圆度仪测量精度高,准确,可靠。 The spindle accuracy of a machine tool depends on the size of the roundness error of the spindle. It directly affects the spindle rotation accuracy, causing positioning error, rotation noise and reduce service life. Therefore, to improve the accuracy of the spindle shaft roundness, try to measure the production site that has become an urgent issue. Currently in the roundness measurement commonly used roundness measurement method and V-shaped measurement method. Roundness measurement accuracy, accuracy and reliability.
