Here, you can find solutions to the common problems of laser cutting machine and laser cutting process.
What is the working principle of laser cutting machine?
Laser cutting is use to illuminate the workpiece with high power density laser beam,to make the workpiece rapidly melt, vaporize, abate or reach the point of ignition. At the same time, the molten material is blown out by the high-speed airflow which is coaxial with the beam to the workpiece. Through moving light spot position by the CNC mechanical system to cut workpiece.
Is laser cutter operating dangerous?
Laser cutting is an environmental friendly method and has no harm to our body. Compared with ion and oxygen cutting, laser produces less dust,. Light and noise.While if you don’t follow the proper operation method. It can also cause personal injury or machine damage.
1.Beware of flammable materials when using machine.Some materials could not by laser machine, including foaming core material, all the PVC materials, high reflective material and so on.
2.In the machine working process, the operator is forbidden to leave to avoid unnecessary losses.
3.Don’t stare at the laser processing. It forbid to observe the laser beams through binoculars, microscope or magnifying glasses.
4.Do not put explosive or flammable materials in the laser processing area.
Which factors could effect the precision of laser machine?
There are many factors can affect the laser cutting accuracy. Some factors are cause by the equipment itself, such as mechanical system precision. Table vibration level, laser beam quality, auxiliary gas. Nozzle etc, some factors are inherent material factors. Because such as the physical and chemical properties of materials , the reflectivity of the material, etc. Besides that other factors like parameters can adjuste base on the specific processing object and the user’s quality requirements, such as output power, focal position, cutting speed, auxiliary gas etc.
How many types of laser machine have? What’s the difference between them?
Currently, lasers for laser processing manufacturing mainly include CO2 laser, YAG laser, fiber laser,etc. Among them, high-power CO2 laser and YAG laser have more applications in the confidentiality processing. Fiber lasers with fiber-optic matrix have obvious advantages in reducing the threshold, the range of the oscillation wavelength and the tunability of the wavelength, it has become the emerging technology in the field of the laser industry.
What’s the cutting thickness of laser cutting machine?
At present, thickness of laser machine is less than 25mm, compare with other cutting methods, laser machine has a clear advantage in material less than 20mm with high accuracy requirement.
What’s the application range of laser cutting machines?
Laser machine has high speed, narrow width, good quality, small heat affecting area and good flexible processing, so it widely use in automobile manufacturing, kitchen industry. Besides that sheet metal processing, advertising industry, machinery manufacturing, cabinet processing elevator manufacturing, fitness equipment and other industries.
