The birth of laser cutting machine has given us an unprecedented improvement in the development of industry. If there were no laser cutting machine, what would happen to many complex fashion products in our life? What will happen to our national economy? Everything is unimaginable! Since the laser cutting machine has played such a great role in our economy and life, the important role of each part of the laser cutting machine is due to the following functions to complete the high-tech product.
1) Machine host part: the machine part of laser cutting machine, the mechanical part that realizes the movement of X, Y, Z axes, including the cutting 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 servo motor.
2) Laser generator: device for generating laser light source.
3) External optical path: refracting mirror, used to guide the laser to the desired direction. In order to avoid failure of the beam path, all mirrors shall be protected by protective covers, and clean positive pressure protective gas shall be introduced to protect the lenses from pollution.
4) Numerical control system: control the machine tool to realize the movement of X, Y, Z axes, and also control the output power of the laser.
5) Stabilized voltage power supply: connected between laser, CNC machine tool and power supply system. It is mainly used to prevent interference from external power grid.
6) Cutting head: mainly including cavity, focusing lens base, focusing mirror, capacitive sensor, auxiliary gas nozzle and other parts. The cutting head drive device is used to drive the cutting head to move along the Z axis according to the program, and is composed of servo motor, screw rod or gear and other transmission parts.
7) Operation console: used to control the working process of the whole cutting device.
8) Water chiller: used to cool the laser generator. Laser is a device that converts electric 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 maintain the normal operation of the laser generator. The water chiller unit also cools the reflector and focusing mirror of the external light path of the machine tool to ensure stable beam transmission quality and effectively prevent the lens from deformation or cracking 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 of the laser vibration and supply the auxiliary gas for the cutting head.
10) Air compressor and air 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 keep the path and reflector working properly.
12) Exhaust dust remover: extract the smoke and dust generated during processing and filter them to make the exhaust gas emission meet the environmental protection standards.
13) Slag extractor: it is used to remove leftover materials and wastes generated during processing.
Based on the above analysis, the role of the laser cutting machine has brought immeasurable wealth to the development of society, solved the rigorous requirements of our daily life in fine, fine and beautiful, and brought us unlimited creative products.
