Laser cutting machine applications

Fiber laser cutting machine it can do both flat cutting and bevel cutting processing, and the edge is neat and smooth, suitable for metal plate and other high-precision cutting processing, applied to sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automotive, grain machinery, textile machinery, engineering machinery, precision parts, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising The laser cutting machine is used in various manufacturing and processing industries, such as metal external processing, kitchenware processing, etc.

Fiber laser cutting machine principle

Laser is to have a laser generator to release a super-density laser beam, through the spot irradiation on the metal plate, high temperature instantly melted or gasified cutting material, and then use high-pressure gas, the melted melt and residue blown off, so as to achieve a cut, and then through the X, Y, Z three-axis linkage, so as to achieve cutting. Fiber laser is to dope the pumping substance into the fiber, after the specific wavelength of laser scour from the semiconductor laser, so that the fiber produces laser and focus on the surface of the workpiece, so that the area on the workpiece irradiated by the light spot local instantaneous melting and vaporization, through the computer-controlled CNC mechanical system to move the spot irradiation position and realize automatic punching. It is a high-tech equipment integrating laser technology, CNC technology and precision machinery technology.

Fiber laser cutting machine features

Fiber laser cutting machine is the use of fiber laser generator as the light source of laser cutting machine, and the laser processing head is a core component of this equipment. Fiber laser cutting machine in the laser processing, how to accurately control the distance between the cutting head and the workpiece and the verticality of the nozzle and the surface of the workpiece is very important. The control will directly affect the quality of the laser cutting machine, so in order to improve the cutting quality and reduce unnecessary losses, it is necessary to install some special sensors on the laser cutting head to ensure that it can produce a stable and consistent cutting quality, and can improve the safety of the production process. Laser cutting head in the workpiece shape changes and surface unevenness, the sensor automatically detects changes and automatically adjusts the height according to the changes, so that it is always the same distance from the surface of the workpiece can be faster processing of materials without continuous supervision, the displacement sensor used at home and abroad today is basically capacitive, its structure and shape with the processing head should live, while equipped with detection signal processing unit.

  1. Using cutting-edge fiber laser, with high photoelectric conversion efficiency and stable performance, the service life of key components can reach 100,000 hours;
  2. Laser generation process does not need to occur gas, air-assisted cutting, fiber optic transmission, no need to adjust the optical path;
  3. Laser transmission by optical fiber, no reflective lens, can save a lot of maintenance costs;
  4. Compared with other media laser equipment, fiber laser cutting machine focus spot is smaller, higher efficiency, better processing quality
  5. Simple structure, small footprint;
  6. Capable of any harsh working environment, i.e. high adaptability to dust, oscillation, shock, humidity and temperature;
  7. High precision and high speed, mainly for fast and precise cutting of metal plates below 4mm.
