Problems solved by technology

Existing this type of remodeling processing and manufacturing device and its processing and manufacturing method, on the one hand, have low production efficiency and low product processing accuracy; It may affect and change the original performance of the material of the superconducting conductor. At the same time, during the production process, the conductor is easily damaged, resulting in a decrease in yield and waste of raw materials. In addition, the modified superconducting conductor is also prone to stress recovery. Deformation, so that the precision of modified products is low, the error is large, and the product qualification rate is low
