3D MICRO ELECTRIC DISCHARGE APPARATUS UNITED POLISHING USING MR FLUID

摘要

A polishing integrated three dimensional micro-discharge machining apparatus using a magnetic viscous fluid is provided to obtain an excellent polishing quality by performing polishing using the magnetic viscous fluid. A polishing integrated three dimensional micro-discharge machining apparatus using a magnetic viscous fluid has a machining tool for machining a machined article. The micro-discharge machining apparatus includes a discharge machining tool exchangeable with the machining tool and a polishing tool(100). The discharge machining tool and the polishing tool are installed in a spindle of a spindle motor. The polishing tool includes an screw coupling portion and a permanent magnet(110).
