12 precautions for using laser engraving machine correctly

Superwave Laser Technology Co.,Ltd | Updated: May 15, 2018

Laser engraving machine of 12 points laser engraving machine also laser marking machine. It is necessary to master methods and careful maintenance in use and maintenance so that the machine can play its role more smoothly


1, the good grounding laser power, laser engraving machine machine tool bed body must have a good grounding protection, ground application is less than 4 Ω special ground. The necessity of grounding is:
(1) the laser power supply can be guaranteed to work normally.
(2) prolong the service life of the laser tube,
(3) it can prevent the outside interference from causing the machine to beat.
(4) prevent the high voltage discharge accidentally caused the circuit damage.


2. The cooling water of laser engraving machine should be free from running water or circulating water pump. Cooling water is taken away the heat generated by the laser tube, the higher the temperature, light output power is lower (in 15 to 20 ℃ temperature is preferred); When the water is broken, it will burst in the tube end due to the heat in the laser cavity, and even damage the laser power supply. Therefore, it is necessary to check the flow of cooling water at any time. When the water pipe has a hard fold or fall off, and the pump fails, it must be repaired in time so as not to reduce power or even damage the equipment.


3. Cleaning and maintenance, good ventilation, cleaning and maintenance of machine tools at any time are necessary conditions for normal working of machine tools. Imagine a person's joints are not flexible, how do they act? In the same way, the guide rail of the machine tool is a high precision core component, which must be wiped clean after each work is completed and kept smooth and smooth. The bearings also need to be lubricated regularly, so that the drive is flexible, accurate, and extend the service life of the machine tool.


4, environment temperature and humidity environment temperature should be in the range of 5 to 35 ℃. Special note: if used in the environment below freezing point, it must be done:
(1) prevent the circulating water in the laser tube to freeze, and the water must be released completely after shutdown;
(2) when switched on, the laser current preheating 5 minutes or more to get to work, in the rainy and humid environment, laser power supply is more need to preheat time longer, does ability after platoon is wet and high pressure, in case of high voltage circuit breakdown.


5, the correct use of "laser high voltage" key button called "laser and high pressure," laser power supply is in standby state, touching the "manual" or computer wrong operation, send out the laser, inadvertently hurt and objects. So the requirements on each job, such as discrete processing, shall, from time to time, turn off the "laser high pressure", (laser current can not pass), and machine operator forbidden to leave at work, in order to avoid accidents, suggested that continuous working time is less than 5 hours, can rest 30 points in the middle.


6. The interference from the sudden power of large electric power and strong vibration equipment can sometimes cause the machine to fail, which is rare, but should be avoided. Therefore, such as large electric welding machine, giant electric mixer and large power transmission and transmission equipment, should be far away. The strong vibration equipment is more self-evident, such as the vibration caused by the forging press and the near distance motor vehicle, and the obvious shaking of the ground is very bad for the precise carving.


7. Lightning protection can be used as long as the building's lightning protection measures are reliable. The first "good grounding" in this section can also help with lightning protection. Special advice: the net electrical instability in the region, such as voltage fluctuation more than 5%), please users to install a capacity of at least 3000 w above regulated power supply, prevent sudden fluctuation burned circuit or a computer.


8. Maintain the stability of PC. Control PC is mainly used for engraving equipment control. In addition to the necessary graphic design software, please do not use special machine. Due to the computer network card and anti-virus firewall, it will seriously affect the speed of the control machine. Please do not install anti-virus firewall on the control machine. If you need network card for data communication, please disable the network card before starting the engraving machine.
9. Guide rail maintenance: the guide rail during the movement process, because the processed materials will produce a large amount of dust. Maintenance method: first, use cotton cloth to wipe off the original oil and dust on the guide rail, wipe clean, then on the surface of the guide rail and the side of a layer of lubricating oil. Maintenance cycle: about a week.
10. Maintenance of the fan: after working for a period of time, the fan and exhaust pipe will accumulate a large amount of dust, which will affect the exhaust efficiency of the fan, resulting in a large amount of smoke and dust. Maintenance method: loosen the connection throat of the exhaust duct and the fan, remove the exhaust duct, and remove the dust from the exhaust duct and the fan. Maintenance period: about one month.
11. Fastening of screws: after working for a certain period of time, the screw of the moving joint will be loose, and when the screw is loose, it will affect the stationarity of the mechanical movement. Maintenance method: tighten the screws one by one with the tools at random. Maintenance period: about one month.
12. Lens of maintenance: machine at work after a period of time, the lens will be due to the work environment on the surface of a layer of ash, which can reduce the reflection mirror reflectance and transmittance of lens, will ultimately affect the work of the laser power. Maintenance method: wipe the surface of the lens clockwise with the absorbent cotton and wipe off the dust. In a word, the attention of laser engraving machine should be done regularly, which will greatly improve our machine life and work efficiency.
