Proper use of laser engraving machine 12 Notes
Laser engraving machine is laser marker of one kind. On the need to master the use and maintenance methods and careful maintenance in order to make the machine more stable play its role.
1, a good grounding laser power, laser engraving machine tool bed must have a good grounding protection, ground application is less than 4Ω dedicated ground. Necessity is grounded:
(1) laser power can be guaranteed to work properly,
(2) to extend the service life of laser tube,
(3) to prevent outside interference caused by beating machine,
(4) to prevent the accidental discharge caused by the high pressure circuit damage.
2, the cooling water flow to the laser engraving machine, whether it be water or a circulating pump, water flow must be maintained. Cooling water is taken away by the heat generated by the laser tube, the higher the temperature, the lower the optical output power (the water temperature to 15-20 ℃ better); when the laser cavity without water due to heat build-up caused by burst pipe end, or even damage the laser power supply. So always check whether the cooling water flow is essential. When hard water off (dead bend) or off, as well as pump failure, it must be repaired in order to avoid power loss and even damage the equipment.
3, cleaning and maintenance, good ventilation, ready to wipe the machine clean conservation, is a necessary condition for the machine to work properly. Imagine people's joints are not flexible, and also how action? Similarly, high-precision machine tool guide is the core component, each item must rub after the completion of clean, keep clean lubrication; each bearing should be regularly oiling, so as to make the drive a flexible, precision machining, to extend the life of the machine.
4, the ambient temperature and humidity of the ambient temperature should be in the range of 5-35 ℃. Special attention is: if used below freezing environment, you must do:
(1) to prevent freezing of water circulating within the laser tube, water must be thoroughly shine after the shutdown;
(2) power, laser current must warm up for 5 minutes or more to work in rainy days and humid environment, the laser power is even more warm-up time longer, can really add high pressure after the humidity and the high voltage circuit to prevent breakdown.
5, the proper use of "Laser high pressure" key, when "Laser high pressure" dial keys, laser power is in the standby state, touch "Manual light" or computer misuse will lase, accidentally wounding injury was. Thus requiring each completed piece of work, if not a continuous process, it should be ready to turn off the "Laser high pressure", (laser current can not turn off), the operator and the machine work is forbidden to leave, to avoid accidents, we recommend continuous working time is less than 5 hours, 30 minutes in the middle to rest.
6, away from the big power interference and strong vibration equipment sudden large electricity sometimes cause machine failure, although rare, but it should be avoided. Therefore, as a large welding machine, power giant mixer and large power transmission equipment, etc., should stay away. Strong vibration devices are more self-evident, such as forging machine, vibration caused by motor vehicles traveling at close range, etc., significantly shake the ground precise carving is very unfavorable.
7, lightning attacks as long as the building can reliable lightning protection measures. The first section of this article, "well grounded" can also contribute to lightning. Special Recommendations: The net electric unstable region (such as voltage fluctuations of more than 5% or more), Please install a capacity of at least 3000W or more power supply to prevent voltage fluctuations sudden burning of the circuit or computer.
8, to maintain the stability of the control PC. PC control is mainly used to control the use of engraving equipment. In addition to the installation of the necessary software graphic design, do not necessarily do special plane. Because the computer to install anti-virus and firewall network card, it will seriously affect the speed controller. Do not install antivirus firewall on the control unit, the card for data communication, disable the card before you start the engraving machine.
9. Maintenance guide: guide the process in motion, the material can easily be processed to produce a lot of dust. Maintenance: first with cotton on the original rail lubricants and dust wipe, wipe clean, and then the track surface and the side coated with oil. Maintenance cycle: about a week.
10. Fan maintenance: fans at work for some time, fans and exhaust pipe will accumulate a lot of dust, the dust will affect the efficiency of the exhaust fan, causing a lot of smoke can not be discharged. Maintenance: the exhaust pipe and fan connections loosen hose clamps, remove the exhaust pipe, the exhaust pipe and clean up the fan dust. Maintenance cycle: a month or so.
11. Screw fastening: motor system at work after a certain time, the movement screw connection will produce loose after screws loose, it will affect the smooth mechanical movement. Maintenance: use the supplied tools individually fastening screws. Maintenance cycle: a month or so.
12. Lens Maintenance: The machine at work for some time, the lens due to the working environment and glue on the surface layer of ash, which will reduce the transmittance and reflectance lens reflex lens, and ultimately affect the power of the laser. Maintenance method: with cotton wool dipped in alcohol to gently wipe the surface of the lens in a clockwise direction, remove dust. In short Note on laser engraving machines we should always do, so our machine life and work efficiency can be greatly improved.
