PROCESSING APPARATUS FOR ELECTRO-CHEMICAL MACHINING

摘要

PURPOSE: An apparatus for electro-chemical machining is provided to enhance machining precision by buffering error with a buffer unit when position error occurs because bottom surface inclines with a certain angle. CONSTITUTION: An apparatus for electro-chemical machining(ECM) comprises a lower guide unit(10), an electrode fixing unit(20), a second guide unit(30) and a frame(40). The lower guide unit is electrically connected to power supply. A workpiece(100) is placed inside the lower guide unit. The electrode fixing unit is arranged at the upper part of the lower guide unit. An electrode(50) in the electrode fixing unit is electrically connected to the power supply. The second guide unit is extended to the lower part of the electrode fixing unit. As the electrode fixing unit vertically moves to the lower guide unit, the second guide unit guides the location of the workpiece in order to connect the workpiece to the electrode. The frame supports and vertically moves the electrode fixing unit.
