Abstract
An apparatus for electrically machining including a rotatable shaft and an electrode for electrically machining is disclosed. The electrode is movably connected to the rotatable shaft. When the rotatable shaft is rotated, the electrode rotates together with the rotatable shaft and moves relative to the rotatable shaft under an action of centrifugal force. Further disclosed is a method for electrically machining including: movably connecting an electrode to a rotatable shaft; inserting the rotatable shaft into a hole in a workpiece, and keeping a gap between the electrode and the workpiece, wherein the hole has a first diameter; powering on the electrode and the workpiece; rotating the rotatable shaft in the hole to generate centrifugal force; and pushing the electrode relative to the rotatable shaft towards the workpiece under an action of the centrifugal force to remove a portion of a material of the hole.
