Laser Cutting Processing Technology in Sheet Metal Industry

威廉希尔官方下载Feb 12, 2020

The sheet metal laser cutting process uses CO2 laser or YAC laser to perform two-dimensional and three-dimensional cutting processing, which has the characteristics of high cutting accuracy. The power of the laser source varies, ranging from 5W to 90kW. The laser cutting of sheet metal parts mainly uses a power laser of 100W ~ 1500W. When the output power of the laser source is less than 1500W, the laser source is in single-mode oscillation mode and can be cut with a width of 0.2mm. The power source is clean and flat after cutting; when the output power of the laser source is greater than 1500w, the laser source is multimode oscillation Mode, can cut 1mm width, but there will be a small amount of dirt after cutting with power.

Auxiliary gases are required for cutting thick plates. Auxiliary gases include air, oxygen, and nitrogen. Among them, nitrogen can prevent the oxidation of the cut surface during the cutting process. Oxygen is suitable for high-speed cutting of thick plates. Sheet metal workshop laser cutting can use CAD or CAM technology to provide processing information and processing parameters for processing workpiece models and lasers, which can quickly and accurately complete production and achieve automatic cutting. In particular, laser cutting requires heavy mold replacement, which can shorten the production preparation cycle and reduce production costs.

As a new process, the sheet metal workshop's laser cutting processing technology is the product of modern scientific development. The laser cutting processing technology, laser welding technology, laser drilling technology and laser forming technology also require skilled technicians in the sheet metal car production Manipulation. With the development of laser material processing technology, the production and processing of sheet metal workshops will inevitably achieve a degree of stability, reliability, efficiency and high automation.
