1. The advancement and retreat of each workstation is driven by a servo motor; 2. With the molding configuration saving function, you only need to call up the program when replacing workpieces (greatly reducing the difficulty of debugging, saving debugging time, and enhancing the consistency of the production products). 3. Add pre-bending function when crimping to improve the yield when rolling stainless steel. 4. The spindle is equipped with a high-power servo motor and a star reducer to improve punching efficiency and indexing accuracy. 5. The flange width adjustment adopts a stepped module, the flanging width is more stable, and the adjustment method saves time. 6. The use of a corner-type star reducer makes the machine lower in height and more efficient in operation.
