Definition and Working Principle of Sheet Metal Laser Cutting Machine

2025-07-28

Speaking of metal processing, the coolest technology now is probably laser cutting. Just like Edward Scissorhands can cut out exquisite ice sculptures in the movie, laser cutting machines can also "cut" out various complex patterns on steel plates. However, it does not use scissors, but high-energy laser beams.


This machine mainly consists of three parts: laser generator, control system and workbench. The laser generator is like its "heart", converting electrical energy into high-energy laser beams. The control system is the "brain", commanding the laser head to move according to the design drawings. The workbench is its "canvas", fixing the metal sheet to be processed. The whole process is like using a magnifying glass to focus sunlight to burn paper, but the energy is countless times stronger.

It is actually quite interesting to operate. The engineer first designs the graphics on the computer and sets the cutting parameters, and then the machine will start working automatically. The laser head will move along the predetermined route, and the released laser beam can instantly heat the metal locally to several thousand degrees, and the incision is thinner than a hair. The most amazing thing is that some high-end models can also automatically adjust the focus position to ensure that materials of different thicknesses can be perfectly cut.


This technology is now widely used. From car parts to mobile phone cases, from art sculptures to kitchen knives, many metal products cannot do without sheet metal laser cutting machines. Compared with traditional cutting methods, laser cutting has higher precision, faster speed, and can handle more complex shapes. However, you must pay attention to safety when operating, after all, the laser beam is not a joke.
