Traditional cutting equipment and processes
The conventional sheet metal processing process is: shear - punch - bend - weld process or flame plasma cutting - bend - weld process. It has obvious shortcomings in the face of multi-species, small-lot, customised, high-quality and short delivery orders:
● (CNC) shearing machines which, due to their predominantly linear cutting, can only be used for sheet metal processing where only linear cutting is required.
● (CNC/brick tower) punching machines have limitations for cutting sheet metal thicker than 1.5 mm and have poor surface quality, are costly and noisy, and are not conducive to environmental protection.
● Flame cutting as the initial traditional cutting method, which is only suitable for rough machining due to large thermal deformation and wide cutting slits during cutting, wasted material and slow processing speed.
● High-pressure water cutting is slow in processing, causing serious pollution and high consumption costs.
