我厂有一台SB—2型百分表检定仪,我们利用这台仪器上的测微头座,装上零级千分尺对一块千分表进行检定,经过多次检定和在千分表检定仪上检定的结果对比,误差没有超过0.001mm,完全满足千分表检定要求。 这是因为千分尺的螺距与千分表测杆齿条段的节距都是0.5mm。当千分尺移动0.01 I plant a SB-2 dial indicator, we use this instrument on the micrometer base, mounted on the zero-micrometer on a dial indicator for testing, after repeated testing and in the dial indicator Comparison of the results of the test, the error did not exceed 0.001mm, fully meet the requirements of the dial indicator. This is because the pitch of the micrometer and the gauge pitch of the gauge rod are both 0.5mm. When the micrometer moved 0.01
