The development trend of laser cutting machine

With the gradual development of laser cutting machines, the power of lasers continues to increase, and laser cutting also develops from the sheet metal processing of light industrial thin plates to the direction of heavy industrial thick plates. With the reduction of the size of the laser, the increase of the power, and the continuous improvement of the auxiliary devices, the laser cutting machine has been closely combined with the laser, power supply, host, control system and cooling water circulation device, forming a small footprint, A complete package of compact laser cutters.


1. Special requirements for cutting special materials


High-speed and high-precision laser cutting machines have created favorable conditions for high-speed and high-precision laser cutting equipment due to the improvement of high-power laser beam patterns and the application of 32-bit microcomputers.


Large-scale laser cutting machines for thick plate cutting and large-size workpiece cutting With the increase of laser power, laser cutting is also applicable from only thin plates to thick plates.


2. Special precision cutting


In order to meet the needs of three-dimensional workpiece cutting in the automobile, aviation and other industries, a variety of five-axis or six-axis three-dimensional laser cutting machines have been developed. The number of CNC axes reaches nine, with fast processing speed and high precision.


There are more and more applications of laser cutting robots on automobile production lines in advanced countries. At present, the three-dimensional laser cutting machine is developing in the direction of high efficiency, high precision, multi-function and high adaptability, and its application range will become larger and larger.


3. Precision cutting


The successful application of laser precision machining technology is in the field of microelectronics developed in the second half of the 20th century, and laser precision machining, as one of the processing technologies of microelectronics integration technology, has been steadily put into mass production. In addition, the manufacture of precision optical instruments, the writing and storage of high-density information, and the medical treatment of biological cells and tissues all require the precision processing characteristics of laser cutting. Select the appropriate wavelength of laser, through various optimized processes and a focusing system approaching the diffraction limit, to obtain high-quality beam, high stability, and output of small-sized focal spot.


4. High-efficiency automatic process cutting


Due to the controllability of the laser output, the laser cutting process can be intelligently controlled by software to automate the process. According to the needs of the production nature, the positioning control of the processing table can be carried out, and the robot hand positioning control of the processing head can be carried out through the optical fiber transmission of the laser, so as to realize fast automatic and intelligent laser cutting. For example, the three-dimensional positioning and cutting of automobile body panels, the cutting of body skeleton, the cutting of gear discs and other parts, etc., have formed a one-stop production line of laser processing and assembly.
