Problems solved by technology

During the moving process of the test probe, the processing machine tool records its movement space coordinates, and then the test probe moves to the small hole on the surface of the workpiece through the conduction detection power perception to complete the determination of the starting position of the capillary electrode electro-hydraulic beam machining. It solves the problem that the capillary electrode in the prior art is fragile, and it is not easy to accurately control the initial gap, so that it is impossible to accurately locate the initial position of the electro-hydraulic beam processing of the capillary electrode
