Laser cutter mainly consists the main machine, light and electricity.
And the whole system is composed of the mechanical part, laser generator + reflector path, CNC controller (electrical control).
The auxiliary equipment of laser cutter include:
stabilizer power supply, water chiller, gas cylinder, air compressor, gas storage tank, cooling dryer, filter, air cleaner, slag discharging machine.
I will split the laser cutter into 13 parts and explain one by one, let’s dive into it.
- 1 1) Laser cutter frame：
- 2 2) Laser generator：
- 3 3) Reflector path：
- 4 4) CNC system：
- 5 5) Regulated power supply：
- 6 6) Cutting head：
- 7 7) Control platform：
- 8 8) Water chiller：
- 9 9) Gas cylinders：
- 10 10) Air compressor, gas storage tank：
- 11 11) Air cooling dryer, filter:
- 12 12) Dust extractor：
- 13 13) Slag discharge machine：
1) Laser cutter frame：
It’s the mechanical part to realize the movement in X,Y,Z-axis, including cutting working platform.
Used to place the cut piece and move it correctly and accurately according to the control procedure. Usually driven by a servo motor.
2) Laser generator：
A device that produces a laser light source.
3) Reflector path：
Refraction mirror for the direction needed for laser orientation.
In order to prevent failure of the beam path, all reflectors shall be protected by a protective cover, and the clean positive pressure protection gas will be used to protect the lens from pollution.
4) CNC system：
Control the laser cutter to achieve X, Y, Z-axis motion, and also control the output power of the laser generator.
5) Regulated power supply：
Connection between the laser generator, laser cutter and power supply system, mainly to prevent the external power network interference.
6) Cutting head：
It mainly includes the cavity, focusing lens seat, focusing mirror, the capacitive sensor and auxiliary gas nozzle.
The cutting head drive device is used to drive the cutting head moves along the z-axis in accordance with the program, which is composed of the servo motor, screw rod or gear, etc.
7) Control platform：
The process of controlling the whole cutting device.
8) Water chiller：
Used for cooling laser generator.
A laser generator is a device that converts electrical energy into light energy, such as a CO2 laser with a conversion rate of 20%, and the remaining energy is converted to heat.
The cooling water takes the excess heat away to keep the laser generator working properly.
The chiller is also cooling the external optical path reflector and focusing mirror to ensure the stable beam transmission quality and effectively prevent the lens from being too hot and causing deformation or crack.
9) Gas cylinders：
Includes laser cutter working medium gas cylinders and auxiliary gas cylinders. Mainly act as industrial gases for the supplement of laser oscillations and auxiliary gas for supplying cutting head use.
10) Air compressor, gas storage tank：
Provide and store compressed air.
11) Air cooling dryer, filter:
Used to supply clean dry air to the laser generator and beam path to maintain the normal work of the pathway and reflector.
12) Dust extractor：
The smoke and dust produced during the process of fabrication shall be filtered and treated to meet the environmental protection standards.
13) Slag discharge machine：
Eliminate the leftover materials and wastes generated during processing.
