Laser cutting machine system consists of laser generator, beam transmission components, worktable (machine tool), microcomputer numerical control cabinet, cooler and computer (hardware and software) and other components.
1, the host part of the machine tool: laser cutting machine part of the machine tool to achieve the X, Y, Z-axis of the movement of the mechanical part, including the cutting work platform. Used to place the workpiece to be cut, and can move correctly and accurately in accordance with the control program, usually driven by servo motors.
2, laser generator: the device that generates the laser light source. For the use of laser cutting, in addition to a few occasions using YAG solid-state lasers, the vast majority of the use of electrical - optical conversion efficiency and can output higher power CO2 gas laser. Because laser cutting on the beam quality requirements are very high, so not all lasers can be used for cutting.
3, external optical path: refractive mirrors, used to direct the laser in the desired direction. In order to make the beam path without failure, all mirrors should be protective cover to protect, and pass into the clean positive pressure protective gas to protect the lens from contamination. A set of good performance lens will be a no divergence angle of the beam focused into an infinitely small spot.
4, numerical control system: control the machine to realize the X, Y, Z axis of movement, but also control the output power of the laser.
5, voltage regulator: connected between the laser, CNC machine tools and power supply system. Mainly prevent the role of external power grid interference.
6, cutting head: mainly including cavity, focusing lens seat, focusing mirror, capacitive sensor and auxiliary gas nozzle and other parts. The cutting head drive device is used to drive the cutting head along the Z-axis direction according to the program, which is composed of servo motor and transmission parts such as screw or gear.
7, the operator console: used to control the entire cutting device work process.
8, chiller: used to cool the laser generator. Cooling water to take away excess heat to maintain the normal operation of the laser generator. The chiller also cools the mirrors and focusing mirrors of the external optical path of the machine to ensure stable beam transmission quality and effectively prevent the lens from being deformed or blown apart due to high temperature.
9, gas cylinders: including laser cutting machine working medium gas cylinders and auxiliary gas cylinders, used to replenish the laser shock of industrial gases and supply cutting head with auxiliary gas.
10, air compressor, storage tank: to 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 operation of the path and reflector.
12, extraction and dust removal machine: extract the smoke and dust generated during processing, and filtering treatment, so that the exhaust emissions in line with environmental protection standards.
13, slag machine: exclude the processing of the edge of the residue and waste materials, etc..
Extended informationLaser cutting machine is the laser emitted from the laser, through the optical circuit system, focused into a high power density laser beam. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam moves relative to the position of the workpiece, it eventually forms a slit in the material, thus achieving the purpose of cutting.
Laser cutting process is an invisible beam of light instead of the traditional mechanical knife, with high precision, fast cutting, not limited to the cutting pattern limitations, automatic layout to save materials, smooth cut, low processing costs and other characteristics, will gradually improve or replace the traditional metal cutting process equipment.
The mechanical part of the laser cutter head has no contact with the workpiece, and will not cause scratches on the surface of the workpiece during the work; the laser cutting speed is fast, and the kerf is smooth and flat, generally without subsequent processing; the cutting heat-affected zone is small, and the deformation of the plate is small, and the cutting slit is narrow; the kerf is free of mechanical stress, and there is no shear burr; the processing precision is high, and the repeatability is good, and it does not damage the surface of the material; the numerical control programmable, and it can be processed with any planar figure.
