The laser engraving machine uses the heat energy of the laser to engrave materials. Compared with the traditional manual engraving method, the laser engraving machine has a wider range of use, and has higher engraving accuracy and faster engraving speed. The following Leapion Laser shares 6 precautions for the correct use of laser engraving machines.
Good grounding has many benefits:
1) The normal operation of the laser power supply can be guaranteed;
2) The service life of the laser tube can be prolonged;
3) It can prevent machine jitter caused by external interference;
4) Prevent accidental circuit damage caused by high voltage discharge.
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℃ water temperature is better); when the water is cut off, the tube end will burst due to the heat in the laser cavity and even damage the laser. 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, and the water pump fails, it must be repaired in time to avoid power drop or even equipment damage.
The laser engraving machine guide rail is a high-precision core component. After each work is completed, it must be wiped clean to keep it smooth and lubricated. Each bearing must also be oiled regularly, so that the drive is flexible, the processing is accurate, and the service life of the machine tool is prolonged.
Special attention should be paid to: if used in an environment below freezing point:
1) Prevent the circulating water in the laser tube from freezing, and the water must be completely discharged after shutting down;
2) When starting up, the laser current must be preheated for more than 5 minutes to work. In rainy and humid environments, the laser power supply needs to be warmed up for a longer time. The high voltage can be applied after the moisture is exhausted to prevent the high voltage circuit from breakdown.
The laser power supply is in a standby state, and when it encounters "manual light output" or computer misoperation, it will emit laser light, inadvertently injuring people and objects.
Therefore, it is required that the "laser high voltage" should be turned off at any time if the work is not continuous, (laser current can not be turned off), and the operator is prohibited from leaving without authorization when the laser engraving machine is working, so as to avoid accidents. It is recommended to work continuously The time is less than 5 hours, and you can rest for 30 minutes.
Such as large electric welding machines, giant electric mixers, and large power transmission and transformation equipment, etc., should be kept away. Sometimes it will cause the machine to malfunction. Although it is rare, it should be avoided as much as possible.
In addition, strong vibration equipment such as forging presses, vibrations caused by close-distance motor vehicles, etc., the obvious shaking of the ground is very unfavorable for accurate engraving.
