Laser engraving machine laser engraving machine will also be a laser marking machine. In the use and maintenance of the need to master the method and careful maintenance, so that the machine can play a more stable role.
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:
2, the laser engraving machine cooling water to smooth whether using tap water or recycling pump, must keep the flow of water smooth. Cooling water takes away the heat generated by the laser tube. The higher the water temperature, the lower the light output power (water temperature of 15-20℃ is preferred). When the water is broken, the tube end will burst because of the accumulated heat in the lasaerpointer cavity, and even damage the laser power supply. Therefore, it is very necessary to check whether the cooling water is smooth at any time. When the water pipe has hard bend (dead bend) or fall off, and when the pump fails, it must be repaired in time, so as not to reduce the power or even cause damage to the equipment.
3, clean maintenance, good exhaust air, wipe the clean maintenance of the machine tool at any time, is the necessary condition for the normal work of the machine tool. Imagine a person’s joints are not flexible, how to move? Similarly, the machine tool guide rail is a high precision core component, each work must be cleaned after completion, to maintain smooth lubrication; The bearings should also be oiled regularly, so that the drive can be flexible and accurate, and the service life of the machine can be extended.
4. Ambient temperature and humidity the ambient temperature should be within the range of 5-35℃.
5, the correct use of the “laser high voltage” key “laser high voltage” dial, the laser power supply is in standby state, encounter the “manual light” or computer error operation, will emit laser, inadvertently hurt people. Therefore, it is required that the “laser high voltage” should be turned off at any time when a piece of work is completed, such as discontinuous processing (the laser current can be turned off), and the operator is forbidden to leave without authorization when the machine is working, so as to avoid accidents. It is suggested that the continuous working time should be less than 5 hours, with a rest of 30 minutes in between.
6, stay away from large electricity and strong vibration equipment sudden large electricity interference, sometimes cause machine failure, although rarely seen, but should try to avoid. Therefore, such as large welding machine, giant electric mixer and large power transmission and transformation equipment, should stay away. Strong vibration equipment is self-evident, such as forging press, close range of motor vehicles walking caused by the vibration, the ground is obviously shaking is very adverse to accurate sculpture.
7, lightning protection as long as the building lightning protection measures can be reliable. The first of this section, “good grounding,” may also help protect against lightning. Special advice: in the area of unstable network power (such as voltage fluctuation of more than 5%), please install a voltage regulator power supply with a capacity of at least 3000W to prevent sudden voltage fluctuation from burning down the circuit or computer.
8. Maintain the stability of control PC. Control PC is mainly used for engraving equipment control. In addition to the installation of necessary graphic design software, do not do special aircraft. Due to the computer installed network card and antivirus firewall, will seriously affect the control machine speed. Please do not install anti-virus firewall on the control machine. If you need network card for data communication, please disable network card before starting engraving machine.
9. Maintenance of guide rail: during the movement of guide rail, a large amount of dust will be generated due to the processed materials. Maintenance method: first, use cotton cloth to wipe off the original lubricating oil and dust on the guide rail. After cleaning, apply a layer of lubricating oil on the surface and side of the guide rail. Maintenance cycle: about a week.
10. Fan maintenance: after the fan works for a period of time, a large amount of dust will accumulate in the fan and exhaust pipe, which will affect the exhaust efficiency of the fan and cause a large amount of smoke and dust cannot be discharged. Maintenance method: loosen the connection throat hoop between the exhaust duct and the fan, remove the exhaust duct and remove the dust in the exhaust duct and the fan. Maintenance cycle: about a month.
11. Screw fastening: after the motion system works for a certain period of time, the screws at the motion joint will become loose, which will affect the smoothness of mechanical movement. Maintenance method: tighten the screws one by one with the attached tools. Maintenance cycle: about a month.
12. Lens maintenance: after the machine works for a period of time, the lens will stick a layer of ash on the surface due to the working environment, which will reduce the reflectivity of the reflecting lens and the transmittance of the lens, and finally affect the working power of the laser. Maintenance method: gently wipe the lens surface clockwise with absorbent cotton dipped in ethanol to remove dust. In short, laser engraving machine attention we should often do, so that our machine life and work efficiency can be greatly improved
