Application fields of fiber laser cutting machine
Fiber laser cutting machine is a high-tech that has been rapidly developed and applied in practice since it came out in 1960. With the continuous deepening of related basic theoretical research and the continuous development of various laser components, its application fields have been continuously expanded, and the application scale has gradually increased, and the economic and social benefits obtained have become more significant.
The laser cutting system is mainly composed of three main parts: machine tool theme, laser, and control system.
The control system is the control center of the entire system. It is responsible for coordinating the normal work of the entire system. It mainly completes the processing track control, focus position control and coordinated control of machine, light, and electricity. The development of CNC fiber laser cutting machine belongs to the category of mechatronics. Its development enables the production system to have a friendly man-machine interface, a convenient and easy-to-learn programming method, and a cutting trajectory control function. It is suitable for industrial site use and greatly improves Increased production efficiency.
The fiber laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material is quickly melted, vaporized, ablated or reached the ignition point, and it is blown away by the high-speed airflow coaxial with the beam Molten the substance, thereby cutting the work piece apart. Laser cutting is one of the thermal cutting methods.
Fiber laser cutting machine is a kind of non-contact processing with high energy density and good controllability. After the laser beam is focused, a very small point of action with extremely strong energy is formed. It has many characteristics when applied to cutting. ：
1) Narrow straight edge cutting front, the smallest heat affected zone adjacent to the cutting edge;
2) Very small local deformation, no mechanical deformation of the workpiece;
3) There is no tool wear, and there is no question of tool replacement;
4) The hardness of the cutting material does not need to be considered, that is, the laser cutting ability is not affected by the hardness of the material being cut
Impact, any hardness material can be cut;
5) It is convenient to combine with automation equipment, and it is easy to automate the cutting process;
6) Because there is no restriction on cutting workpieces , The laser beam has unlimited profiling cutting capabilities.
Application of fiber laser cutting machine: Fiber laser cutting machine is mainly used to replace punching and blanking dies and punching trimming dies, so as to save 1 pair of punching and blanking dies on the mold. Two sets of punching and trimming dies can be saved on the drawing die. Under special circumstances, if there are corner cutting dies and blanking dies, it can also be saved. Generally speaking, laser cutting can cut cold-rolled and hot-rolled steel plates with a thickness of 0.1～16.0mm, copper, stainless steel plates, paper, wood, cloth, etc. The general tolerance is within ±0.1mm. The bracing is simple and convenient, quick to replace, low pollution, relatively low production cost, fast programming and correction procedures, and easy to change the hole position deviation and inappropriate hole diameter in the later period. Generally, there is no burr in the trimming process. Since the program can be used repeatedly, the fiber laser cutting machine can be changed and continued to run through programming, which is relatively low-demand.
The fiber laser cutting machine can adjust the program according to the production needs and quality requirements to realize the running speed of the laser cutting head. At present, the specific steps used by the fiber laser cutting machine are: process the drawings to be processed, program it with the software provided by the fiber laser cutting machine manufacturer, and open the file with the operating software of the fiber laser cutting machine, according to the processed material Set parameters such as energy and speed before running. The fiber laser cutting machine will automatically cut according to the flight path generated by the software after receiving instructions from the computer. The use of laser cutting, no molds, high dimensional accuracy of the cut parts, high cutting speed, small deformation, high cut finish, low processing cost, will gradually improve or replace the traditional cutting process used by the company.
