Start the machine and use the slow-rotating recorder to feed paper at a low ratio in the morning. In the 10th gear, use a large-scale stimulus flow. The format recording requires a large adjustment agent. Preheat for 20 minutes. Use the internal parts to pull the recording pen to the center line of the recording paper ±10 grids for inspection. Take the largest change in the record standard, and then use the same method to check the rest of the service files.
Install a sample in the lower tilt head room at 1: and load it. , use the Smm probe to measure the small and large heads of the sample, the recorder is calibrated to 1μm, select the low measurement speed, select the small and large heads of the plate and the right tooth surface, take the difference between the actual calibration value of the plate
at [: the lower point of the sample, use the 5mm probe to measure the small head of the sample, the recorder is calibrated to 1μm/grid, select the low measurement accuracy and the first wave measurement, the curve is sampled 2° after the starting point, and one point is sampled every 5 points, a total of points are taken. Align the first point, take the remaining corresponding points of the maximum change
two-way trace, the method in the batch is the main method, and method 6) is the alternative method.
The gear teeth of the transmission are calibrated as
, select the lowest speed, measure 8 times from the marked tooth, take the measured position of each rotation and the actual value of the gear teeth; the gear teeth and the gear teeth are calibrated as
, select the lowest speed, measure 6 times from the marked tooth, take half of the accumulated value of each step, add one of the next steps and measure 10 times at the same time to double the standard value (12):
