A laser engraving machine, as the name suggests, is an advanced device that utilizes a laser to engrave the material to be engraved. Unlike mechanical engraving machines and other traditional manual engraving methods,laserpecker 2 laser engraver mechanical engraving machines use mechanical means, such as diamond and other extremely hard materials to engrave other objects.

Laser engraving machine can improve the engraving efficiency and make the surface of the engraved place smooth and round. It can quickly reduce the temperature of non-metallic materials, reducing deformation and internal stress.laser pecker 4 According to the different laser light source, it can be divided into CO2 non-metallic laser engraving machine and fiber metal engraving machine. The glass laser tube is usually used more in China, and there are some high-end laser engraving machines with CO2 metal RF tube. So, what matters need to be noted when using laser engraving machine?

The installation pivot point of the laser tube should be reasonable, and the pivot point should be at 1/4 of the total length of the laser tube. If the pivot point is not reasonable, it will lead to the deterioration of the laser tube spot pattern and affect the output of laser power.laser pecker pro Therefore, read the "Precautions for the Use of Laser Tube" carefully during the installation process.

The cooling system should be grounded and the water tank and water circuit should be cleaned frequently. The temperature control point of the cooling temperature control water tank should be set reasonably, otherwise it will lead to problems such as easy breakage of the laser tube, power loss by condensation, and dislodgement of the cold water head. These problems may lead to the machine can not work properly, need to replace the laser tube frequently.

Water protection should be checked and cleaned frequently. If the cooling water cannot flush the water protection float switch or the water protection float switch does not reset, the shorting method cannot be used to solve the emergency. In addition, the cooling water quality should be good, if the water nozzle aluminum oxide is serious, you need to regularly clean the water pump and water pipe, water protection in the dirt. Otherwise, it may cause the laser tube to burst or the cold water head to fall off.

The suction unit also needs to be checked and cleaned regularly. If the fan duct is not cleaned, a lot of smoke and dust can not be discharged, will seriously contaminate the lens and the laser tube, so that the various mechanical and electronic components are easy to oxidize resulting in poor contact.

Focusing lens and reflector also need to be checked. After working for a period of time, the frame will heat up, the surface of the lens will be discolored and rusty; dehiscence and cracking all need to be replaced. Especially for customers who use large air pumps and air compressors, water can easily accumulate on the focusing lens, so it is necessary to check the cleanliness and quality of the lens (laser tube outlet) optical system on time.

The working environment of the machine must not be too harsh either. If the ambient temperature is higher than 30 degrees Celsius or lower than 18 degrees Celsius, too much dust or serious air pollution, the machine will be seriously damaged and the failure rate will keep rising. In addition, the electrical parts are easy to have problems under humid environment. Therefore, it is recommended that customers improve the working environment and frequent maintenance.

The power of the power grid should also be matched. The power distribution and contact points of each part of the whole equipment should be good (fan, water cooler, laser machine, laser power supply, computer should be independent power supply).

The working current of the laser tube should also be reasonably controlled. Can not be a long time in the high light intensity working condition; to rationalize the application of laser and energy saving; optical path system should be kept clean and correct, otherwise it may lead to premature aging and rupture of the laser tube. Therefore, the light intensity should be adjusted to 50-60% when the laser machine is working and then the working speed should be adjusted according to the material, so as to achieve the best working condition.

The base plate and the material to be processed should also be flat, otherwise it will cause inconsistency in the focal length or the problem of not cutting through in some places. This will lead to increased light intensity and also rapid aging of the laser tube.

The heat dissipation of the laser power supply should be smooth. Once the operating current is cranked up to 50% or more, the temperature will rise dramatically very high, which will increase the laser power supply failure rate. Some machines allow you to remove the side door to dissipate the heat emitted from the power supply directly.
