A workpiece 2 and a negative electrode cleaning module 15 respectively correspond to the inductive machining electrode 13. A power module 17 (as shown in the fourth figure) can be electrically connected to the workpiece 2, so the workpiece 2 can have a plurality of positive charges, and the power module 17 can also be electrically connected to the negative electrode cleaning module 15, so that The negative electrode cleaning module 15 may have a plurality of negative charges.

The electrolyte is supplied between the workpiece 2 and the inductive machining electrode 13 and between the negative electrode cleaning module 15 and the inductive machining electrode 13 respectively. When the inductive electrochemical machining device 1 performs electrochemical machining, as shown in the fourth figure, the positive charges on the surface B1 of the inductive machining electrode 13 corresponding to the workpiece 2 (surface A) will induce a plurality of negative charges, That is, the inductive machining electrode 13 has these negative charges relative to the surface B1 of the workpiece 2 (surface A), so that the inductive machining electrode 13 can perform electrochemical machining on the workpiece 2. Similarly, as shown in the fourth figure, the negative charges on the surface B2 of the inductively processed electrode 13 corresponding to the negative electrode cleaning module 15 (surface B3) will induce a plurality of positive charges, Therefore, the negative electrode cleaning module 15 can electrochemically process the surface B2 of the induction-processed electrode 13, that is, it can clean the surface of the induction-processed electrode 13. In this way, the inductive electrochemical machining device 1 can simplify the required power supply circuit. The detailed description is as follows.

Please refer to the third and fourth figures together, which are side views and schematic views of the induction electrochemical machining device of the present invention. As shown in the figure, the base 11 may have a workpiece processing area 110, and the inductive machining electrode 13 is disposed on the base 11 and corresponds to the workpiece processing area 110. The negative electrode cleaning module 15 is opposite to the induction processing electrode 13.

In this embodiment, the inductive electrochemical machining device 1 may include a power module 17, a first electrode terminal 171 of the power module 17 is electrically connected to the workpiece 2 to be processed, and the workpiece 2 is moved to the base 11 In the workpiece processing area 110, the second electrode terminal 172 of the power module 17 is electrically connected to the negative electrode cleaning module 15.
