How to maintenance the UV printer grating ruler?

Hyunvan UV Printing manufacturer is specialized in printing field.and give the proposals as below,

In the normal use of grating rulers, we must pay attention to reasonable maintenance methods. The precautions for use of grating rulers are summarized from many experiences as follows:

1. If possible, it is best to pass clean (filtered and dried) compressed air to the grating ruler, so as to prevent the oil, liquid and gas surrounding the grating ruler from entering the grating ruler and contaminating the grating ruler.

2. Add a protective cover to the scale as much as possible, and clean up the chips and oil splashed on the scale in time to strictly prevent any foreign matter from entering the inside of the scale shell.

3. Regularly check whether each installation connection screw is loose, especially the screw that fixes the reading head. I have encountered many machine tool linear axes runaway or unable to return to the reference point due to the loosening of the fixing screws of the reading head.

4. In order to ensure the reliability of the grating scale sensor, the grating scale surface and the indicating grating surface can be cleaned and wiped with absolute ethanol at regular intervals to keep the glass grating scale surface clean.

5. The grating ruler is strictly prohibited from violent vibration and beating, so as not to damage the grating ruler, such as the grating ruler breaks.

6. When installing the grating ruler and the reading head, pay special attention to the distance between the reading head and the grating ruler. Far or near may cause damage to the reading head or damage to the scale in the housing of the grating ruler, or even scrap the grating ruler.
