Maintenance Manual of the Laser Engraving Machine

- Dec 24, 2019-

1.Filling lubricating oil to linear guide

As we know, the smoke and dust which is generated by the engraving and cutting will harm the guide rail after a period of usage, so we need to do the daily maintenance of the guide rail. Please turn off the laser engraving machine and cut the power, clean the guide rail with a clean mull, then please drop the lubricating oil on the guide rail, try to move the slide rod and make sure that the oil comes into it. Make the slide rod move on the guide rail after filling the oil, now we need to install the guide rail firstly, please do not fix the guide rail firstly, install the screws in the right position and keep the slide ray on the even level. Then fix the belt and slide rod well, install the lens and then adjust the destination of X light.

2.Clean the reflector and focusing mirror

After a period of usage of the laser engraving and laser cutting machine, the smoke and dust will adhere to the surface of the reflector and mirror, which will affect the engraving and cutting depth and also will affect the engraving and cutting precision. We need to clean the three reflectors and one focusing mirror with pure alcohol weekly.

3.Oil-filling for the bearing

A laser engraving machine is equipped with lots of bearings, in order to keep the good engraving and cutting result, part of bearings need to be refilled with oil regularly (except the oil-retaining bearing). Wipe off the surface dust on the bearing with the clean mull, take a piece of the injector and suck some engine oil inside, then fill the bearing with pinhead and move the bearing at the same time.

4.Adjustment of synchronous belt

There are some synchronous belts on one laser engraving machine if the synchronous belt is too loose which will result in the double images of the engraved words if the synchronous belt is too tight which will result in the abrasion of the synchronous belt. After a period of usage, please adjust the taut screws of synchronous belt, adjust the synchronous belt until its degree of tightness is suitable, it is adequate when there is no double images of the engraved words and the noise of the laser engraving and laser cutting machine is very low, or you can consult our technician.

5.Maintenance of the laser tube

The laser tube of the laser engraving machine is using the cycle water as a cooling system and as time goes on, there will be some furings inside the laser tube. We we can put a little vinegar into the cycle water, the vinegar will melt the furing. After that, we shall use some clean water to clean the tube. So the laser tube will be in the best working condition and its life will become longer.
