What to do if the laser cutting machine does not emit light

1. Check whether the water tank of the fiber laser cutting machine has an alarm

(1) Alarm, the water inlet and outlet behind the water tank are connected with water pipes , The water tank is energized to see if it alarms. If you call the police, the water tank is broken. If there is no alarm, the water path of the fiber laser cutting machine will be blocked. Check whether the water pipe is bent or pressed by something, and whether there is debris in the water in the water tank (change the pure water in the water tank).

(2) No alarm, check whether the power supply fan of the fiber laser cutting machine rotates. The power supply fan of the fiber laser cutting machine rotates, and the laser power supply is short-circuited with a wire.

2. Is the fiber laser cutting machine glowing?

(1) When glowing, the line on the motion control card is loose, and the active control card is broken (replace the card).

(2) No light is emitted, and the laser power supply is damaged. (The fiber laser cutting machine is less damaged) (check whether the high-voltage end of the fiber laser cutting machine has ignition, it is easy to burn the laser power supply and the electronic components of the card during ignition). The power supply fan of the fiber laser cutting machine does not rotate. Use an electric pen to test whether the 22V port of the laser power supply has electricity. If there is electricity, the laser power supply is broken (repair or replace the power supply); if there is no electricity, check the power switch and circuit problems of the fiber laser cutting machine.

Laser cutting is prone to hair stimulation light:

Laser cutting machines are very common in sheet metal processing. Because of its high processing efficiency and good finished products, it has become the standard of many sheet metal processing stations. However, some customers will cut more workpiece burrs when using laser cutting machines. Many people think this is a quality problem of laser cutting machine products, but this is not the case.

In the sheet metal processing process, the gas purity and parameter settings of the laser cutting machine will affect the final processing. The equipment + gas + parameters are well adjusted, and the workpiece is cut without burrs.

How do glitches occur?

In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine processes the workpiece, the amount of laser beam irradiating the surface of the workpiece causes the surface of the workpiece to evaporate and achieve the purpose of cutting. However, there is auxiliary gas here.

Auxiliary gas means that after the irradiated surface of the workpiece is vaporized, the scum on the surface of the workpiece is blown off. If the auxiliary gas is not used, after the scum is cooled, burrs will form and adhere to the cutting surface. Therefore, the purity of the gas should be high, and you can change to a better gas supplier. The purity of the gas is very important. It is best not to use cylinder gas, because after two fillings, the purity is not good and gas will be wasted.

Another reason is the quality of the equipment itself and the parameter setting factors. Therefore, when a customer purchases a laser cutting machine, the operator should debug the equipment. Therefore, the cutting parameters should be adjusted as best as possible. The air pressure, flow, focal length and cutting speed must be adjusted many times. The parameters provided by the machine cannot be used to cut exquisite workpieces.

If a material has burrs, then the material can be classified as defective. The more burrs, the lower the quality.

are an important part of the society and they come in handy in any place where there are punching machine manufacturer in need of powder coating machine price.
