Abstract
Electric discharge electrodes are disposed at equal intervals along a circumference about a rotary shaft, and provided so as to be capable of being brought into and out of contact with vanes such that one electric discharge electrode corresponds to one vane. The electric discharge electrodes each have an electrode surface along a surface to be machined of a corresponding one of the vanes. After the electric discharge electrodes each move radially inward toward the rotary shaft, the rotary shaft rotates and electrochemical machining is thus performed while the electrode surface and the surface to be machined are close to and thus face each other.
Claims5
An electrochemical machining apparatus that electrochemically machines an impeller circumferentially having a plurality of roughly molded vanes, comprising:
- a support that supports the impeller;
- a rotary shaft that holds the support rotatably;
- and
- a plurality of electric discharge electrodes disposed at equal intervals along a circumference about the rotary shaft, and provided so as to be capable of being brought into and out of contact with the plurality of vanes such that one electric discharge electrode corresponds to one vane;
- wherein
- the plurality of electric discharge electrodes each have an electrode surface along a surface to be machined of a corresponding one of the plurality of vanes, and
- after the plurality of electric discharge electrodes each move radially inward toward the rotary shaft, the rotary shaft rotates and electrochemical machining is thus performed while the electrode surface and the surface to be machined are close to and thus face each other.
