how to bring a laser engraver and cutter function into fully play? —the most important thing is the daily maintenance for its efficient and safety. if did it, the lifetime of machine can be longer, the processing quality can be kept and improved in order to achieve high efficiency.
please execute the following steps seriously
1. connect the ground wire for safety
the laser power and machine body should be protected by ground wire well, the ground wire should be less than 4 for special purpose. the necessities are (1) keep the power work formally, (2) keep the laser tube life time longer, (3) can prevent the machine body shake from external disturbance. (4) prevent high voltage discharge from circuit damage. please connect the ground wire by all means.
2. keep the cooling water freely
please keep the water freely whether is tap water or circulating water pump. the cooling water can carry off the heat from the laser tube, the higher the water temperature is, the lower the light output power (15-20 c water is good), when water break, the tube will be heater and be easily broken, even damage the laser power. so it is necessary to check the cooling water frequently. when the tube have the hard fold or the water pump do not work, please check and maintain on time, in case the low output power make the equipment damage.
3. keep clean & maintenance, discharge air well and wipe usually.
it is necessary to clean and maintain the machine body for its formal working. the guide roll is the key part of the machine, it must be cleaned and kept lubricating, each bearing need to be filled oil periodely, which can make the driver flexible, processing precision and extend the machine lifetime.
4.temperature and humidity
the working temperature should be in the arrange 5-35 c.two things have to be done (1) prevent the circulating water in the tube freezing, please make the water out of the tube after machine stopped. (2) the laser power should be preheat above 5 minutes before working, the preheat time is longer in raining and humidity weather, make sure the moisture go out fully before the high pressure taken, in case the high pressure circuit broken.
5.proper use of laser high pressure key
the laser power is under stand by situation after the laser high pressure key opened, when you touch the manual light or wrong computer operation, the laser light will be out to hurt the people or goods unconsciously. it is better to stop the laser high power after each job, the (laser power can open), operator is prohibited to leave during machine working, in case accident happened, we suggest the continuously working time is below 5 hours, 30 minutes rest interval can be acceptable.
6. keep far from huge electricity quantity and strong quaking equipments
sometimes, the electricity quantity interference can make the machine fail, it is rare, but it is better to be avoided. therefore, please keep far from the large electric transmission and transformation equipments like larger welder, huge electric mixer and so on as well as the strong quaking equipment like forging press, the quaking from the earth is not good for the engraving effect.
7. prevent the thundering and lightening attack
only if the building prevents measures is reliable, that is no problem on this point.
please install a stable power at least 3000w above to prevent the circuit or computer burned in the unstable web and electricity areas.
8. maintain the pc operation stability
pc controlling is mainly used for engraving machine; please use the pc only for engraving machine except install the necessary graphic design software.
due to the web card and virus fire wall installed, the pc speed is influenced, please do not install the virus fire wall in the computer, and forbid the web card before engraving machine working.
9�� guide rail maintenance
during the guide rail working, there is massive dust from processing materials.
maintenance method: firstly, wipe the original lubricating oil and dust on the guide rail by cotton fabric, then coat a layer of lubricating oil on the surface and side face of the guide rail. the maintenance period is one week around.
10�� lower maintenance
after the blower working for a while, there is massive dust in the blower and tubes, the dust can affect the efficiency to make the smoke dust flow out incapable. maintenance method: unload the exhaust duct and clean the dust. maintenance period: once a month
11 screws fastening:
when machine worked for a long time, the moving system screws becomes loosen, which will affect the machine smoothness. maintenance method: fasten the screws by the gift tolls. maintenance period: one month around.
12 lens maintenance:
after long working time, the lens surface has a layer of dust, which will reduce the reflection ratio and transmittance to affect the working efficiency. maintenance method: wipe the lens dust by cotton bud dipped alcohol.
