The maintenance of the
CMM needs to be maintained in all aspects. As the key component of the
CMM, the grating ruler is also a very precise part. Whether the maintenance is reasonable or not directly affects the accuracy of the CMM and the life of the grating ruler. For the specific maintenance and cleaning methods of the coordinate measuring machine grating ruler, please refer to the recommendations of industry insiders.
1. The power supply should be turned off when the grating ruler sensor and the digital display socket are plugged and unplugged.
2. Add a protective cover as much as possible, clean up the cutting and oil splashed on the ruler in time, and strictly prevent any foreign matter from entering the interior of the casing.
3. Regularly check whether each connecting screw is loose.
4. In order to prolong the life of the dust-proof sealing strip, a thin layer of silicone oil can be evenly coated on the sealing strip, and be careful not to splash on the scribed surface of the glass grating.
5. In order to ensure the reliability of the grating sensor, the grating surface and the indicating grating surface can be cleaned and wiped with ethanol mixture (50% each) at regular intervals to keep the glass grating surface clean.
6. It is strictly forbidden to vibrate and beat the grating ruler sensor violently, so as not to damage the grating ruler, such as the grating ruler breaking, and the grating ruler sensor will fail.
7. Do not disassemble the grating scale sensor by yourself, and do not arbitrarily change the relative distance between the main grating and the auxiliary grating, otherwise, on the one hand, the accuracy of the grating scale sensor may be damaged, and on the other hand, it may cause the relative friction between the main grating scale and the auxiliary grating scale. Damage to the chrome layer also destroys the grid lines, thus causing the grating ruler to be scrapped.
8. Care should be taken to prevent oil and water contamination on the surface of the grating ruler, so as not to damage the line fringe distribution of the grating ruler and cause measurement errors.
9. The grating sensor should try to avoid working in the environment of severe corrosion, so as not to corrode the chromium layer of the grating and the surface of the grating, and damage the quality of the grating.
To clean the grating ruler of the
CMM, you can use a absorbent cotton ball dipped in anhydrous alcohol, and wipe the cotton ball from one end of the grating to the other end, then replace the cotton ball, and then wipe it with a clean cotton ball. The cotton ball cannot be reused. , be careful not to wipe back and forth. Do not touch the reading head during the wiping process, and do not let the fibers of the cotton ball stick to the grating. The static electricity of the reading head will attract the fibers and affect the reading. The grating ruler of the CMM should not be wiped frequently, but once a quarter or half a year.
