The flexible electrode 2 is in a fan shape, so that the discharge area is increased, and the discharge power and the discharge efficiency are improved.
Further, as a preferred embodiment of the present invention, but not limited thereto, the tool 3 is formed with a first cutting edge 31 and a second cutting edge 32, the first cutting edge 31 extends in the axial direction of the holder 1 and protrudes from the upper side surface of the holder 1, and the second cutting edge 32 extends in the radial direction of the holder 1 and protrudes from the outer peripheral side of the holder 1. This setting is convenient for the installation and the dismantlement of cutter 3, and the setting of a plurality of cutting edges can improve the flexibility ratio that cutter 3 used.
Further, as a preferred embodiment of the present invention, but not limited thereto, the holder 1 is formed with a mounting hole 10 into which the flexible electrode 2 is inserted. Since the flexible electrode 2 is composed of a plurality of the metal wires 22, this arrangement can improve the stability of the assembly of the flexible electrode 2 and prevent the flexible electrode 2 from loosening and scattering.

Specifically, two ends of the tool 3 in the radial direction of the tool holder 1 are a C end and a D end, two ends of the discharge surface 21 in the radial direction of the tool holder 1 are a C 'end and a D' end, respectively, and the adjusting component 4 makes the C end and the C 'end located on a first circle and makes the D end and the D' end located on a second circle, where the first circle and the second circle are concentric circles.
Correspondingly, the adjusting assembly 4 includes an elastic member 41 for elastically pushing the flexible electrode 2 along the radial direction of the tool holder 1, and an adjusting rod 42 for adjusting the pushing force of the elastic member 41, wherein the elastic member 41 is made of rubber, and the adjusting rod 42 is made of a bolt.

s2: driving the discharge surface to move, so that a softened surface formed on the surface to be processed of the workpiece by the discharge surface is superposed with a cutting surface formed on the surface to be processed of the workpiece by the cutter;
s3: adjusting the distance between the discharge surface and the surface to be processed of the workpiece to ensure that the discharge surface is not contacted with the surface to be processed of the workpiece completely or is contacted with the surface to be processed of the workpiece completely or partially, starting a power supply, rotating a tool apron, softening the surface to be processed of the workpiece through discharge of a flexible electrode, and cutting the softened surface to be processed by a milling cutter.
In step S1, the discharge surface can be matched with the surface to be processed of the workpiece, so as to avoid collision between the flexible electrode and the workpiece during processing of the workpiece.
In step S3, when the discharge surface is not in contact with the surface to be processed of the workpiece, a gap is formed between the discharge surface and the surface to be processed of the workpiece, and the flexible electrode does not discharge in contact, so that the discharge of the flexible electrode is more uniform and the discharge effect is better because the discharge surface and the surface to be processed of the workpiece are in contact matching in step S1; when the discharge surface is completely contacted with the surface to be processed of the workpiece, the flexible electrode is in contact discharge, and the discharge surface can be adjusted and deformed in time in the processing process, so that the surface to be processed of the workpiece can be uniformly softened by the electric arc, and meanwhile, the scraps can be swept away from the surface to be processed, so that the quality of the surface to be processed of the workpiece is improved; when the discharge surface is contacted with the part of the surface to be processed of the workpiece, the effect of gap discharge and the effect of contact discharge are achieved, and a cleaning effect is achieved.
When the flexible electrode 2 discharges to soften the surface of the workpiece to be processed, the spraying head 303 sprays electrolyte toward the gap formed between the workpiece and the flexible electrode 2.
