The basic structure of laser cutting machine and the function of each component

Laser cutting machines are constantly upgraded and vigorously developed for use in various industries, such as product development or medical, electronics, and clothing industries. CARMAN HAAS China Laser Cutting Machine Manufacturer in order to let everyone have a deeper understanding of laser cutting machines, today we will talk about some basic structures of laser cutting machines and the functions of each component.

The basic structure of a laser cutting machine is mainly composed of the combination of body, light and electricity. The whole machine includes three major parts: the body frame part (mechanical part), laser, laser head, motion system and console (electrical control part) part.
The above is equipped with auxiliary equipment for laser cutting: stabilized power supply (need to be used in conjunction with laser tubes), chiller (used for cooling the machine, which can prolong the service life of the machine), air compressor, cooling dryer, filter, Exhaust dust collector, slag discharger, etc. constitute the system integration of a complete set of equipment.

In order to better operate the laser cutting machine in production, we need to understand the function of each part of the laser cutting machine. The main functions of each component are as follows:

1. The frame part of the fuselage (mechanical part): the machine part of the laser cutting machine, the mechanical part that realizes the movement of the X, Y, and Z axes, including the cutting work platform. It is used to place the workpiece to be cut, and can move correctly and accurately according to the control program, usually driven by a three-phase stepping motor.

2. Laser: 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 prevent failure of the beam path, all mirrors should be protected by protective covers, and clean positive pressure protective gas should be introduced to protect the mirrors from contamination.

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

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

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

7. 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.

8. Chiller: used to cool the laser tube. Laser tube 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 tool to ensure stable beam transmission quality and effectively prevent the lens from being deformed or burst due to excessive temperature.

9. 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.

10. Air cooling dryer and filter: used to supply clean dry air to the light generator and beam path to keep the path and reflector working properly.

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

The advantages of laser cutting machine are incomparable with other mechanical equipment, it replaces labor and other ordinary machines to better complete the objects that need to be processed, cut and engraved.
