Heli tells you the 12 characteristics and applications of laser cutting and engraving machine:
1. The laser engraving machine
has a good grounding laser power supply, the machine bed must have good grounding protection, and the ground wire should be a dedicated ground wire less than 4Ω. The necessity lies in: (1) to ensure the normal operation of the laser power supply, (2) to extend the life of the laser tube, (3) to prevent the machine from beating due to external interference, and (4) to prevent high-voltage discharge from accidentally causing circuit damage. Good grounding, be sure!
2. The cooling water of laser engraving machine
should be unblocked. Whether it is using tap water or circulating water pump, the water must be kept flowing. The cooling water takes away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20 ° C water temperature is preferred). When the water is cut off, the tube end will explode due to heat accumulation in the laser cavity, and even the laser will be damaged. power supply. Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, so that the pump fails, it must be repaired in time to prevent the power from dropping or even causing damage to the equipment.
3. The laser engraving machine
needs to be cleaned and maintained, with good ventilation, and it is necessary to wipe the cleaning and maintenance of the machine at any time, which is a necessary condition for the normal working of the machine. Imagine that people's joints are not flexible, how can they act? For the same reason, the guide rail of the machine tool is a high-precision core component. After each work is completed, it must be wiped clean and kept smooth and lubricated; the bearings must also be regularly oiled, so as to make the drive flexible, accurate and extend the service life of the machine tool.
4. The laser engraving machine
needs suitable ambient temperature and humidity. The ambient temperature should be in the range of 5-35 ° C. Special attention should be paid to: (1) To prevent the circulating water in the laser tube from freezing, and to completely expose the water after shutdown; (2) When the machine is turned on, the laser current must be preheated for 5 minutes. The above can work. In rainy days and humid environments, the laser power needs to be warmed up for a longer time, and the high voltage can be applied only after the moisture is drained to prevent breakdown of the high voltage circuit.
5. When the laser engraving machine
needs to use the "laser high voltage" key and the "laser high voltage" key correctly, the laser power supply is on standby. When encountering "manual light emission" or computer misoperation, the laser will be emitted, inadvertently injuring people or injured people. Therefore, it is required to turn off the "laser high voltage" whenever the work is completed, such as discontinuous processing (the laser current can be turned off), and the operator is forbidden to leave while the machine is working to avoid accidents. It is recommended that the continuous working time be less than After 5 hours, you can rest for 30 minutes.
6. The laser engraving machine
is far away from the sudden interference of large power and strong vibration equipment, which sometimes causes the machine to malfunction. Although rare, it should be avoided as much as possible. Therefore, such as large electric welding machines, giant electric mixers and large power transmission and transformation equipment, etc., should be kept away. Strong vibration equipment is self-evident, such as forging presses, vibrations caused by close-range motor vehicles walking, etc., the obvious vibration of the ground is not good for accurate carving.
7. The laser engraving machine
has lightning protection as long as the lightning protection measures of the building are reliable. The first "good grounding" in this section can also help with lightning protection.
Here, Wickman, the Nanjing engraving machine brand manufacturer, particularly recommends: In areas with unstable network power (such as voltage fluctuations of more than 5%), please install a regulated power supply with a capacity of at least 3000W or more to prevent sudden voltage fluctuations. Burn out of circuit or computer.
8. The laser engraving machine
needs to maintain and control the stability of the PC.
The control PC is mainly used for controlling the engraving equipment. In addition to installing the necessary graphic design software, please do not use it exclusively for special planes.
After the computer is installed with network card and anti-virus firewall, it will seriously affect the speed of the control machine. Please do not install an anti-virus firewall on the control machine. If you need a network card for data communication, please disable the network card before starting the engraving machine.
9. The laser engraving machine
needs the maintenance of the guide rail: during the movement of the guide rail, a large amount of dust will be generated due to the processed material. Maintenance method: First wipe off the original lubricating oil and dust on the guide rail with a cotton cloth. After cleaning, apply a layer of lubricating oil on the surface and sides of the guide rail. Maintenance cycle: about a week.
10. The laser engraving machine
needs the maintenance of the fan: After the fan is operated for a period of time, a large amount of dust will accumulate in the fan and the exhaust pipe. The dust will affect the exhaust efficiency of the fan and cause a large amount of smoke and dust to be discharged. Maintenance method: loosen the connection hose of the exhaust pipe and the fan, remove the exhaust pipe, and clean out the dust in the exhaust pipe and the fan. Maintenance cycle: about one month.
11. The laser engraving machine
needs the fastening of the screws: After the motion system works for a certain period of time, the screws at the joints of the motion will become loose. After the screws are loose, the stability of the mechanical movement will be affected. Maintenance method: Fasten the screws one by one with the tools provided. Maintenance cycle: about one month.
12. Laser engraving machine
needs lens maintenance: After the machine works for a period of time, the lens will be coated with a layer of ash due to the working environment. This will reduce the reflectivity of the reflective lens and the transmittance of the lens, and ultimately affect the laser Working power. Maintenance method: wipe the lens surface clockwise with an absorbent cotton dipped in ethanol to wipe off the dust.
