Sheet metal industry has always been full of new technology, new equipment iterative update. From wire cutting to plate cutting, from plasma to numerical control punching, and now to laser cutting, robot and other interventions, with its advantages of high precision, high speed, flexible processing adaptability and other advantages, it has become a new direction of sheet metal technology. With the continuous optimization of laser cutting price, more and more industries begin to use laser cutting in batches. At the same time, the homogenization competition among sheet metal manufacturers is increasingly intensified.
