Due to improper use of equipment or no routine maintenance of the case there will be a variety of failures, of which the axial error is often encountered by many users. So how to detect the axial error of the instrument?
Detection of the axial error of the instrument:
1, calibration equipment to adjust the workbench, so that the flat face and spindle axis of rotation accurate vertical.
2, the flat or standard hemisphere placed on the adjustable table outside the middle school calibration, the spherical probe and the flat face or the top of the standard hemisphere (the following are the same, omitted) contact, and the sensor value at zero Swing nearby is the smallest.
3, when the spindle rotation 3 weeks, the boot measurement, the smallest area method to assess its roundness, as the test results.
Block by increasing the magnification until 10000 times. Adjust the radial position of the sensor to minimize the radius of gyration of the touch probe.
4, the filter knob set 1 ~ 15 wave / turn, magnification knob set 1 000 times, force measuring knob set to measure the middle of the external instrument calibration force position. Install the shoulder with spherical probe on the sensor (if possible, load the sensor laterally so that the probe touches the flat face).
