How to avoid problems of laser engraving machine

Laser engraving can improve the efficiency of engraving, make the surface smooth and round, quickly reduce the temperature of the non-metallic materials, and reduce the deformation and internal stress of the objects; It can be widely used in the field of fine carving of various non-metallic materials. The use of laser engraving machine in the advertising industry is increasing. Let's simply understand how to avoid the problems of laser engraving machine. Of course, it's not absolutely avoided, but as far as possible.


How to avoid problems of laser engraving machine


1 The fulcrum of laser tube installation should be reasonable. The fulcrum should be at 1 / 4 of the total length of laser tube. Otherwise, the spot pattern of laser tube will become worse. In some cases, the spot will become several points during a period of time, resulting in the decrease of laser power and failure to meet the requirements, resulting in continuous tube replacement;


2 The cooling system should be grounded, the water tank and waterway should be cleaned frequently, and the temperature control point of the refrigeration temperature control water tank should be reasonable, otherwise the laser tube is easy to be damaged and dewed, the power of the laser tube will be reduced, the cold water head of the tube will fall off, the service life of the tube will be greatly shortened, and sometimes it can not work, resulting in continuous tube replacement;


3 The water protection should be checked and cleaned frequently. The cooling water can't be flushed. The water protection float switch or the water protection float switch can't be reset. The short circuit method can't be used to solve the urgent problem. The cooling water quality is good, the aluminum oxide of the nozzle is too serious, so it is necessary to regularly clean the dirt in the water pump, water pipe and water protection after using for a period of time, otherwise the laser tube will burst or the cold water head will fall off; Laser carving machine commonly used in the market


4 The suction device shall be checked and cleaned regularly to clean the fan air duct. Otherwise, there will be many smoke dust that can not be discharged, which will seriously and quickly pollute the lens and laser tube, so that the mechanical and electronic parts are easy to oxidize and cause poor contact;

5 The focus mirror and reflector are inspected, and the frame will heat after working, and the surface of the lens will be discolored and rusty; The film breaking is the object to be replaced, especially for many customers using large air pump and air compressor, so that the water will soon accumulate on the focusing lens, so the cleaning and quality of the optical circuit system of the lens (the optical outlet of the laser tube) must be checked on time;


6 The working environment of the machine cannot be too bad. If the environment temperature is higher than 30 ℃, and below 18 ℃, too much dust and serious air pollution are caused, so the machine is seriously damaged and the failure rate is rising; It is easy to have problems with electrical accessories in humid environment. Therefore, we specially remind customers to improve the working environment and maintain the machine frequently;

7 The power of the power grid shall be matched. The power distribution and contact points of all parts of the whole equipment shall be good (fan, water cooler, laser machine, laser power supply and computer shall be powered independently);

8 The current of laser tube should be reasonable, and it can not be in the light intensity of 90-100 for a long time; We should rationalize the application of laser and save laser energy; The optical system should be clean and correct, otherwise the laser tube will be aged and broken prematurely. Therefore, the working time of laser machine should be adjusted at 50-60%, and then the working speed should be adjusted according to the material, so that is the best working state of the laser tube;


9 The base plate and the processed material should be flat, otherwise the focal length is inconsistent, and some parts cannot be cut through, so the intensity of light should be increased and the laser tube will be aging rapidly;


10 The cooling of laser power supply should be smooth, otherwise, once the working current is adjusted by more than 50% the temperature will rise very high, which will increase the failure rate of laser power supply.
