In the construction machinery industry, when faced with specific plate thicknesses, as long as the workpiece hole diameter requirement is greater than or equal to the corresponding minimum diameter value, and the roughness and diameter size requirements are within the cutting machine's guarantee range, laser cutting can be used directly, eliminating the drilling process and improving labor productivity. Laser cutting can use the dotting function to determine the hole position, saving the time for locating holes in subsequent drilling processes and eliminating the cost of making drilling templates, thus improving production efficiency and product precision.
