1. Lubricating oil for linear guide:

    Metal laser cutting machine used for a period of time, engraving, cutting produced smoke, dust on the guide has a corrosive effect, so the guide should be regularly maintained.

 

    Clean the clean soft cloth guide rail with the power supply of the metal laser cutting machine, and then drip the lubricating oil on the guide rail. After the lubricating oil is finished, let the slider roll back and forth in the guide rail to ensure that the lubricating oil enters the inside of the slider.When the oil is finished, let the slider roll back and forth in the guide rail, then it is necessary to install the guide rail first, pay attention to do not fix the guide rail first, fix all the fixing nails, keep the level, fix the belt and the slider, then install the lens, adjust the X direction is finished.

 

2. Wipe the reflector and focusing mirror:

    Metal laser cutting machine, metal laser cutting machine used for a period of time, smoke will adhere to the surface of the lens, affect the engraving, cutting depth, will also affect the engraving, cutting accuracy.Generally in a week or so with anhydrous alcohol will be three mirrors, a focusing mirror carefully wiped clean.

 

3.bearing oil;

    Metal laser cutting machine USES a large number of bearings, in order to ensure good cutting, engraving effect, some bearings need to be lubricated regularly, with a clean soft cloth to wipe off the floating earth on the bearing, with a needle pipe oil into the needle pipe, and then slowly inject the bearing with a needle, slowly rotate the bearing during oil filling.

 

4. Elastic adjustment of synchronous belt (belt) :

    There are several synchronous belts in the transmission system of metal laser cutting machine. If the synchronous belt is too loose, the engraving font will double. If the synchronous belt is too tight, the synchronous belt will wear down.After using for a period of time, please adjust the tensioning screw of the synchronous belt, adjust the synchronous belt to the appropriate elastic, engraving text does not appear double shadow, and metal laser cutting machine, metal laser cutting machine running noise is very low, or consult the technical personnel of the manufacturer.

 

5.Maintenance of five laser tubes:

    Metal laser cutting machine for laser tube is the use of circulating water cooling, use for a long time, the tube there will be some white scale, we can in the circulating water add a little vinegar, will pipe water to remove, and then use clean water to laser tube inner loop washed clean, so that the laser tube will be in the best working state, the life will be extended

 

    In the use of laser engraving cutting machine, for safety protection, for efficient production, the most important thing is the daily safety maintenance and maintenance of equipment.Achieved not only can prolong the service life of the machine, but also can always maintain and improve the processing quality of the production, and finally achieve stable and high efficiency.



Notes:

1.Good grounding

    Laser power supply, the machine itself must have a good grounding protection, ground application is less than 4 Ω special ground.The necessity lies in :(1) it can ensure the normal operation of laser power supply, (2) it can prolong the service life of laser tube, (3) it can prevent the machine from jumping caused by external interference, and (4) it can prevent accidental circuit damage caused by high voltage discharge.Good grounding, be sure!

 

2.Cooling water should be unimpeded

    Cooling water mode Color water-cooled laser engraving and cutting machine, whether using tap water or circulating water pump, must keep the water flow unimpeded.Cooling water is to take away the heat generated by the laser tube, the higher the water temperature.The lower the optical output power is, the water will be cut off due to the heat accumulated in the laser cavity and the tube end will burst, or even damage the laser power supply.Therefore, it is very necessary to check whether the cooling water is unblocked at any time.When the water pipe has hard fold or fall off, so that the water pump fails, it must be repaired in time, so as not to reduce the power or even cause equipment damage.

 

3.Clean and maintain, good ventilation, wipe at any time

    The cleaning and maintenance of the machine is a necessary condition for the normal operation of the machine.Imagine that the joints are not flexible, how can you move?In the same way, the machine guide is a precision core component, each top must be cleaned after the completion of the work, keep smooth lubrication, each bearing should also be regular oil injection, so as to make the drive flexible, accurate processing, prolong the service life of the machine.

 

4.Ambient temperature and humidity

   The ambient temperature is in the range of 5-3535℃.In particular, if it is used in the environment below the freezing point, it must be done: 1) Prevent the circulating water in the laser tube from freezing, and release the water thoroughly after the shutdown;2) When starting up, the laser current must be preheated for more than 5 minutes before it can work. In cloudy, rainy and humid environment, the laser power supply needs to be preheated for a longer time, and the high voltage can only be added after the humidity is removed to prevent the breakdown of the high voltage circuit.
