Daily maintenance and maintenance of coordinate measuring machine


1、 Daily maintenance:

1. Check and drain the water in the air compressor, filter, air tank and pipeline before starting. In rainy days, check every four hours

2. When the air conditioner is turned on, wipe the guide rail of the measuring machine with wiping paper and absolute alcohol (the machine cover and main and auxiliary legs can only be wiped with water). Clean the indoor environment and keep it clean

3. Check whether there are obstacles in the guide rail area of the measuring machine, and whether the measuring head will collide with the table or workpiece when the measuring base rotates

4. Check that all cables, gas pipes, ground wires, etc. of the measuring machine are connected normally and reliably

5. Check whether the indoor temperature and humidity are within the required range (20 ℃± 2 ℃, 40%~65%)

6. Turn on the air source switch and check whether the input air source pressure meets the requirements (≥ 0.55Mp)

7. Turn on the UPS power supply and check whether the power supply is normal (220V± 10%)

9. Keep the temperature and humidity of the testing room, avoid cleaning work such as scrubbing the floor with water before holidays, and clean it at work

2、 Regular maintenance


1. Measure typical parts and check whether the accuracy of the measuring machine changes greatly and meets the requirements. It is especially necessary to check when the seasons change or the environmental conditions change

2. Check whether the filter is clean. Check whether the air supply pipe is clean


1. Clean the filter core

2. When the seasons change, check the temperature and humidity changes of the environmental conditions

3. Test typical parts to determine the accuracy change of the measuring machine

4. Check the accuracy of the detection system, that is, the probe. Estimate the life of the probe and properly prepare the spare parts (especially the trigger probe)

Every year:

1. It is recommended to calibrate the accuracy of the measuring machine every year

2. Check the safety of compressed air pipeline and air receiver

3. Check the mechanical parts of the measuring machine, such as the air floating block, transmission belt and motor

4. Clean the grating ruler and check the working condition of the reading head

5. Clean the control system and check whether the internal cable head is loose
