Control box sheet metal operation process: When riveting, consider the height of the stud to choose the same different molds, and then adjust the pressure of the press to level the surface of the stud and the workpiece to avoid the stud not pressed firmly or pressed out beyond the workpiece surface, resulting in the workpiece being scrapped. Welding includes argon arc welding, spot welding, carbon dioxide protection welding, manual arc welding, etc., spot welding should first consider the position of the workpiece welding, and consider the accurate position of the positioning tooling in the mass production of stainless steel sheet metal. Airuida Precision Sheet Metal Company has advanced precision CNC processing equipment, such as 2 sets of Japanese AMADA CNC turret punching machines and 5 sets of Japanese AMADA CNC bending machines.
