Several key technologies of laser cutting machines are integrated technologies combining optics, mechanics, and electronics. In laser cutting machines, the parameters of the laser beam, the performance and precision of the machine and CNC system directly affect the efficiency and quality of laser cutting. Especially for parts requiring high cutting precision or significant thickness, the following key technologies must be mastered and resolved:
Focus Position Control Technology
One of the advantages of laser cutting is its high beam energy density, typically 10W/cm². Since energy density is inversely proportional to area, the focal spot diameter should be as small as possible to create a narrow kerf; simultaneously, the focal spot diameter is also directly proportional to the depth of focus of the lens.
