What are the main components of a laser cutting machine?

    Laser cutting machines are mainly used for cutting, have stable power requirements, can cut metal and non-metal products. The cutting deviation can be accurate to the millimeter, and there is no burr after cutting. The laser cutting machine can replace some dangerous work and complete some difficult cutting, which is not only suitable for the cutting of large-scale heavy industrial products, but also for the cutting of household products and artworks. The main components of the laser cutting machine are summarized as the following 13 points.

    1. The main part of the machine body: The machine body of the laser cutting machine is the mechanical part that realizes the movement of X, Y and Z axis, including the cutting work platform, which is used to place the workpiece, and can move correctly and accurately according to the control program, usually by the servo motor driven.

2. Laser generator: a device that generates a laser light source.

3. External light path: refraction mirror, used to guide the laser in the required direction. In order to ensure that the beam path does not fail, all reflectors should be protected by protective covers, and clean positive pressure protective gas should be introduced to protect the mirrors from contamination.

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

5. Regulated power supply: connected between the laser, the CNC machine and the power supply system. It mainly plays the role of preventing external grid interference.

6. Cutting head: It mainly includes parts such as cavity, focusing lens holder, focusing mirror, capacitive sensor and auxiliary gas nozzle. The cutting head driving device is used to drive the cutting head to move along the Z-axis according to the program, and is composed of a servo motor and transmission parts such as a screw rod or a gear.

7. Operating table: used to control the working process of the entire cutting device.

8. Chiller: used to cool the laser generator. Laser is a device that converts electrical energy into light energy. For example, the conversion rate of CO2 gas laser is generally 20%, and the remaining energy is converted into heat. The cooling water takes away the excess heat to keep the laser generator working properly. The chiller also cools the external optical path reflector and focusing mirror of the machine to ensure stable beam transmission quality and effectively prevent the lens from being deformed or burst due to excessive temperature.

9. Gas cylinder: including the working medium gas cylinder and auxiliary gas cylinder of the laser cutting machine, which are used to supplement the industrial gas for laser oscillation and the auxiliary gas for supplying the cutting head.

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

11. Air cooling dryer and filter: used to supply clean dry air to the laser generator and beam path to maintain the normal operation of the path and reflector.

12. Exhaust dust collector: extract the smoke and dust generated during processing, and filter it to make the exhaust gas discharge meet the environmental protection standards.

13. Slag discharge machine: remove the leftover material and waste generated during processing.
