Common breakdowns and solutions of CNC laser engravers
With the development of science and technology, computer numerical control laser engraving machine has been widely used. It not only improves the texture and quality of products, but also reflects the modern technology. But in use, there are still some common problems. Today we will learn about the common faults and solutions of CNC laser engraving machine together.
First of all, the air temperature of the working environment is too high or too cold, or the air inside the cabinet is too damp, resulting in the control system and screws of the CNC laser engraver failing to operate normally. The solution is to check the indoor temperature and humidity of the working environment, and then adjust the indoor temperature and humidity according to the corresponding standard.
Second, the faults and solutions related to parts of the CNC laser engraver.
1. The motor is unable to start. Checking whether the output voltage of the power supply is normal and whether the cable connection is correct. If the voltage is normal, replace the motor.
2. The light path of the laser head is loose. Check if the connecting screws are loose. If its loose, tighten it, if its damaged, replace it with a new one.
3. The working voltage of the controller is too low or intermittent power supply. Check the voltage of the power supply, check for loose wires, connect the wires tightly, or use a stable power source such as UPS to supply power.
Third, the computer program errors caused by the failure.
1. The engraving speed of the CNC laser engraver is slow or incorrect. Check if the parameter data is correct, if not, modify it; check whether the engraving speed is too slow or too fast, and adjust it accordingly.
2. Programming errors. Check the programming syntax or modify the incorrect words.
3. The electrical appliance overload protection is abnormal. Check whether the current of the program exceeds the rated output current of the engraving machine and adjust the engraving parameters accordingly.
In addition, when using the CNC laser engraver, the spindle should be adjusted according to the cutting depth, the focal length of the laser head should be adjusted when cutting the curved surface, the working table should be kept clean, the smoke should be discharged in time, and the laser head should be inspected and maintained regularly.
These are some common faults and solutions of the CNC laser engraving machine. During the use of the CNC laser engraver, we should pay attention to the operation and maintenance of the machine, choose the right engraving procedure and solve the machine phenomenon in time, in order to make the CNC laser engraver have better precision and cutting effect.
