A semi-submerged micro electrolytic wire cutting fixture and radial flushing method

Abstract

The invention discloses a clamp for semi-immersed type electrochemical micro linear cutting machining and a radial flushing method. A linear electrode is fixed to the clamp and placed above an electrolytic bath. One end of a flushing hole is connected with an adjustable micro peristaltic pump, and the other end is connected with an inner cavity. Electrolyte in the electrolytic bath is pumped intothe clamp by the adjustable micro peristaltic pump and enters the inner cavity through the flushing hole. When a workpiece is machined, the linear electrode is aligned at the workpiece and transversely moved and fed towards the workpiece. When the workpiece is in contact with the linear electrode and electrochemical machining begins, machining products produced in the machining process are removedthrough relative movement between the linear electrode and the workpiece and the flushing liquid of the adjustable micro peristaltic pump. Through the special clamp and the flushing method, the removal of floccules and air bubbles, which are produced in the machining process, by the linear electrode is ensured, the machining stability is greatly improved, and the operation is convenient and easyto realize.

Problems solved by technology

But when the processing gap is too small, there are two key problems

First of all, although processing requires a large amount of electrolyte, in some cases, processing completely immersed in the electrolyte will have a certain impact on the electric double layer on the surface of the workpiece

[0005] Secondly, the processed products (floc and air bubbles) produced during the processing cannot be discharged in time, and the fresh electrolyte cannot enter the processing gap in time, the floc will prevent the reaction from proceeding, and the air bubbles will cause the wire electrode to bend even damaged
