Laser cutting machines have no problem cutting steel plates less than 10mm thick. However, if you want to cut thicker steel plates, you often need a high-power laser with an output power of more than 5kW, and the cutting quality is significantly reduced. Since high-power laser equipment is expensive and its output laser mode is not conducive to laser cutting, traditional laser cutting methods do not have advantages when cutting thick plates. There are the following technical difficulties in cutting thick plates with metal laser cutting machines...
