Numerical control technology has been fully applied in Sheet Metal Processing. Its many advantages make sheet metal processing manufacturers work more smoothly. Not only the quality of sheet metal processing parts has been improved, but also the work efficiency has been improved. Non-standard cabinet custom sheet metal processing manufacturers use various numerical control technologies to provide customers with a wealth of sheet metal processing parts products. What are the advantages of numerical control in sheet metal processing? (1) Simple and convenient to use, low investment cost. It has its own unique advantages in the processing of various sheet metal parts, especially for the processing of complex shapes or thin plate parts, which can automatically complete the processing of parts. According to the requirements of the drawings, the holes with different size requirements and shape requirements can be automatically processed, and the larger holes and contour curves of various shapes can be produced and processed in a small step-by-step manner using small punching dies. In addition, the simple structure of the die can also be processed for sheet metal parts with special processing techniques, such as shallow stretching, flanging holes, etc. Compared with the traditional stamping, the die is simpler, the processing range is wide, and the processing capacity is significantly improved. It is particularly suitable for mass production or various forms of product processing. This is very beneficial for processing enterprises to keep up with the pace of market development and meet product demand. Moreover, because of the reduction of costs in all aspects, the economic benefits of the enterprise have been effectively improved. (2) The product quality is stable and the processing accuracy is high. For the processing of sheet metal parts, the workpiece has good flatness, higher punching accuracy, stable forming quality, and good product consistency. (3) Effectively improve production efficiency. The automatic control system can realize the processing of small batches of workpieces and the simultaneous processing of different parts, and the processing speed is fast. Because of the reduction of subsequent processing and other links for the numerical control of sheet metal parts, the production is greatly improved and the production cost is reduced.
