The application of laser cutting machine has promoted the rapid development of sheet metal processing. Its advantages such as high processing precision, fast cutting speed and flexible processing have eliminated the traditional sheet metal processing mode.Laser cutting machine in the end is a kind of what magical equipment, the following Wuhan high energy laser to introduce to you what parts are composed of, let us have a deeper understanding of the laser cutting machine.Laser cutting machine system is generally composed of laser generator, (outside) beam transmission module, workbench (machine tool), microcomputer numerical control cabinet, cooler and computer (hardware and software).

1. Machine main machine part: the machine part of laser cutting machine, the mechanical part to realize the movement of X, Y and Z axes, including the cutting platform.Used to position the cut workpiece and move it correctly and accurately according to the control program, usually driven by servomotor.

2. Laser generator: A device for generating laser light source.For the purpose of laser cutting, except for a few occasions to use YAG solid laser, most of them use CO2 gas laser with high electric-optical conversion efficiency and high power output.Because laser cutting requires high beam quality, not all lasers can be used for cutting.Gaussian mode is suitable for carbon dioxide laser less than 1500W, low order mode 100W-3000W, more than 3000W multi-mode.

3. External light path: refracted reflector is used to guide the laser in the required direction.To prevent beam passage from failure, all mirrors should be protected by a protective cover and pass through a clean positive pressure protective gas to protect the lens from contamination.A good set of lenses will focus a beam with no divergence Angle into an infinitesimal spot.A lens with a focal length of 5.0 inches is usually used.7.5-inch lens for >12mm thick material only.

4. Numerical control system: the machine tool is controlled to realize the movement of X, Y and Z axes, and the output power of the laser is also controlled.

5. Regulated power supply: connected with laser, CNC machine tool and power supply system.Mainly plays the role of preventing interference from external power grid.

6. Cutting head: mainly including cavity, focusing lens seat, focusing mirror, capacitive sensor and auxiliary gas nozzle and other parts.The cutting head driving device is used to drive the

cutting head along the Z axis according to the program. It is composed of servo motor and drive parts such as screw or gear.

7. Operating table: It is used to control the working process of the whole cutting device.

8. Chiller: Used to cool laser generator.Laser is the use of electric energy into light energy device, such as CO2 gas laser conversion rate is generally 20%, the remaining energy will be converted into heat.Cooling water carries the excess heat away to keep the laser generator working properly.The chiller also cools the external optical path mirror and focusing mirror of the machine tool to ensure the stable beam transmission quality and effectively prevent the lens from deformation or cracking due to excessive temperature.

9. Gas cylinders: include working medium gas cylinders and auxiliary gas cylinders of laser cutting machine, industrial gas used to supplement laser oscillation and auxiliary gas used to supply cutting head.

10. Air compressor and air storage tank: provide and store compressed air.

11, air cooling dryer, filter: used to supply clean dry air to laser generator and beam path, so as to keep the path and mirror working normally.

12. Air extraction and dust removal machine: the smoke and dust generated during processing are extracted and filtered to make the waste gas emission conform to the environmental protection standards.

13. Slag eliminator: remove the leftover material and waste materials produced during processing.

Laser cutting machine manufacturers have a lot of, but the choice of laser cutting machine must choose a qualified manufacturer, its assembly process and workmanship are exquisite are accumulated deep experience.Hebei guohong laser technology  has been established for 18 years. It is mainly engaged in metal laser cutting machines and is the leading manufacturer of laser cutting machines.Welcome to visit our customers consultation.
