how does laser cutter work
How a laser cutter works?In laser cutting, the horizontal laser beam emitted by the laser turns into a vertical downward laser beam through a 45° total reflection mirror, and then is focused by a lens to form a very small spot at the focal point. When the spot is irradiated on the metal material, the metal material is quickly heated to the vaporization temperature and evaporates to form a hole. As the beam moves on the material, and with auxiliary gas (carbon dioxide gas, oxygen, nitrogen, etc.) to blow away the molten waste, the hole continuously forms a very narrow (such as 0.1mm or so) cut the seam to complete the cutting of the material.
why use fiber laser cutting machine?
1.The cutting quality is good.
A. The laser cutting incision is narrow, the two sides of the incision seam are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.

- Fiber laser cutting head
The fiber laser cutting head is a laser output device, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the fiber laser cutting machine will walk according to the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled according to different materials, different thicknesses, and different cutting methods.
- Laser lens Laser lenses are mostly used in the entire fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as total reflection lens, semi-reflective lens, focusing lens, etc. The quality of the lens directly affects the output power of the laser, and also affects the performance of the entire fiber laser machine.
- Host workbench
The bed, beam, worktable, and Z-axis system of the fiber laser cutting machine are collectively referred to as the host. When the fiber laser cutting machine performs cutting, first put the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of the Z axis. Users can adjust the parameters according to their needs.

how to maintain fiber laser cutter?how to prolong life of laser cutter?
How to maintain a laser cutter? How to extend the service life of laser cutting machine? Every day before and after operating the fiber laser cutting machine, some maintenance work must be done to extend the service life, so how to do the daily maintenance of the fiber laser cutting machine? When using a fiber laser cutting machine to process objects, you need to learn the equipment use and maintenance skills of the fiber laser cutting machine in order to better play the efficiency of the equipment and maximize the efficiency of the equipment.
- First of all, the operator must be trained, familiar with the structure and performance of the equipment, and master the knowledge of the operating system. Follow the rules of the cutting machine and operate safely and independently. Of course, if any mechanical equipment wants to be used for a long time, maintenance is the first element. If you do not pay attention to maintenance, the best equipment will not be durable. Then the maintenance of fiber lasercutter is mainly concentrated in the following 6 aspects:
- Maintenance of the lens
- Before starting the laser cnc, check the mirrors 2 and 3 to check whether there is dust on the mirror surface or whether the mirror surface is damaged. The maintenance of the lens of the laser cutting machine is very important, and it is very important to ensure the quality of the beam.
The lens of the laser cutting machine is easily contaminated by smoke and dust. It is recommended to clean it once a day before starting work. Generally, anhydrous industrial alcohol acetone is used to clean the lenses. Different lens cleaning methods are different. When the mirror surface is flat and there is no lens holder, use lens paper to clean; when the mirror surface is curved or the mirror surface has a lens holder, please clean it with a cotton swab.
When using the lens, pay attention to focusing the lens, protecting the lens, QBH head and other optical surfaces, and do not touch it directly with your hands to prevent scratches or corrosion of the lens.
- Maintenance of the cutting head
Before using every day, check whether the laser is emitted from the center of the nozzle, if not, please readjust the calibration.
Before cutting, adjust the height of the cutting head to a suitable drilling position.
When cutting, always observe whether it is cutting. If you do not cut, first raise the cutting head by hand to stop cutting, check whether the cutting parameters are correct, whether the nozzle and the protective mirror are damaged, adjust them, and then return to the uncut state, and then continue cutting.
When cutting, observe whether the cutting piece is turned over or up. If so, take over when the cutting head collides with the workpiece. If the plate is not flat, adjust it to the appropriate drilling height (3-5mm) at any time.
When cutting, observe whether the cutting head catches fire. If it catches fire, stop cutting, check whether the nozzle is worn, and judge whether the focus is changing. If so, increase or decrease the pad according to the situation.
- Chiller maintenance
The chiller is used as the cooling equipment of the fiber laser cutting machine. The chiller guarantees the normal operation of the fiber laser cutting machine at a constant temperature. Pay attention to the water temperature when working for a long time. It is recommended that the water temperature be below 35 degrees; in winter, the circulating water should be prevented from freezing and the laser tube from freezing and cracking (antifreeze can be added).
The water inside the chiller needs to be replaced regularly, because long-term use is prone to scaling and reduces the cooling effect. Generally, clean the chiller 1-2 times a month, replace the internal circulating water, and use distilled water without impurities, such as pure water or mineral water. But be careful not to use tap water.
- Maintenance of the guide rail frame
Each rail rack needs to be cleaned regularly to remove dust and other debris to ensure the normal operation of the equipment. The frame should be wiped and lubricated frequently to ensure that the lubrication is free of debris.
In addition, always check the steel belt to ensure that the steel belt is tight. Regularly check the straightness of the track and the verticality of the machine. If abnormalities are found, maintenance and adjustments will be carried out in time, usually at an interval of 6 months.
- Attention to the working environment
The environment where the machine is located must be pollution-free, free from interference and influence from strong electricity, strong magnetism, etc. Pay attention to anti-vibration and anti-loose: the cutting machine is particularly sensitive to vibration. The working environment should be far away from places with vibration sources such as punches and heavy objects. If the connection is loose, it is recommended to install anti-vibration pads and re-reinforce it.
In addition, pay attention to anti-interference and anti-leakage: the electromagnetic environment of the cutting machine mainly includes the surrounding electromagnetic field, the quality of the power supply, and the interference of signal electrical noise.
- Daily maintenance requirements
- Check and clean the workbench every day to keep the laser and laser cutting machine clean and tidy.
- Check whether the X, Y, and Z axes can return to the origin every day, and check whether the position of the striker of the origin switch is offset.
- Check whether the connecting wire is tight and disconnected every day, and check whether the fan of the control box is normal.
- Clean the X-axis screws and Y-axis screws every week, and then add oil.
- Check whether the fixing screw of the screw nut is damaged, and whether the joint between the water pipe and the air pipe is damaged or blocked.
