The laser cutting machine system consists of a laser generator, a beam transmission component, a workbench (machine tool), a microcomputer numerical control cabinet, and a cooler, which constitute a computer (hardware and software) and other components.
1. Machine tool host part: the machine tool part of the laser cutting machine, the mechanical part that realizes the X, Y, Z axis movement, 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 servo motor.
2. Laser generator: device that generates laser light source. For laser cutting applications, except for a few occasions where YAG solid-state lasers are used, most CO2 gas lasers with high electro-optical conversion efficiency and high output power are used. Because laser cutting requires high beam quality, not all lasers can be used for cutting.
3. External optical path: refractor, used to guide the laser to the desired direction. In order to prevent optical path failure, all reflectors should be equipped with protective covers, and clean positive pressure protective gas should be introduced to protect the reflectors from pollution. A group of lenses with good performance will focus the beam without divergence angle into an infinitely small spot.
4. CNC system: control the machine tool to realize the movement of X, Y and Z axes, and control the output power of the laser at the same time.
5. Stabilized power supply: connected between laser, CNC machine tool and power supply system. It mainly plays the role of preventing external power grid interference.
6. Cutting head: mainly including cavity, focusing lens frame, focusing lens, capacitive sensor, auxiliary air nozzle and other components. 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 components.
7. Operation console: used to control the working process of the whole cutting device.
8. Cooler: used to cool the laser generator. The cooling water takes away excess heat to keep the laser generator working normally. The chiller also cools the external light path reflector and focusing mirror of the machine tool to ensure stable beam transmission quality and effectively prevent the lens from deforming or bursting due to high 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 oscillation and the auxiliary gas of the cutting head.
10. Air compressor and air storage tank: provide and store compressed air.
11. Air-cooled dryer and filter: used to provide clean and dry air for the laser generator and optical path to maintain the normal operation of the optical path and reflector.
12. Exhaust gas dust collector: extract the smoke and dust generated in the processing process and filter it to make the exhaust gas discharge meet the environmental protection standard.
13. Slag extractor: remove leftovers and waste materials generated during processing.
