Problems solved by technology

In order to ensure the high precision of the workpiece, the lathe processing method generally needs to adopt multi-process processing, the work efficiency is low, the cost is high, and high processing accuracy cannot be guaranteed.
The heat treatment processing method is to stamp the workpiece after heat treatment. This processing method is single, the efficiency is low, and the accuracy still needs to be guaranteed in the subsequent reprocessing stage.
Electrolytic machining has high processing efficiency, good surface quality after machining, and a wide range of applications. The disadvantage is that electrolytic machining has many influencing factors, and the technical difficulty of small-scale machining surface processing is high, and the accuracy requirements cannot be guaranteed.
[0004] Therefore, the processing method in the prior art cannot realize high-precision workpieces, especially the high applicability and high-precision processing of small processing surfaces such as small straight holes, variable diameter holes, small arc grooves, etc., which affects high precision. Efficiency and quality of workpiece processing
