PROCESS OF ELECTROCHEMICAL MACHINING OF ROD WORKPIECES FOR MANUFACTURE OF MEDICAL TOOLS Russian patent published in 1996 - IPC

Abstract RU 2064538 C1

FIELD: stomatology, microsurgery, neurosurgery and other branches of medicine. SUBSTANCE: invention relates to electrochemical processes of machining for manufacture of medical tools where usage of profiled rod articles is required. Process includes submersion of workpieces into bath with electrolyte and removal from it. During electrochemical machining workpiece is evenly moved along bath and rotated about own axis. Anode density of current is decreased across workpieces when they are removed from electrolyte as compared with submersion but not more than 4 times. Anode density of current across workpieces is decreased by change of distance between workpieces and cathode. Screens and/or additional cathodes are positioned in end zones of workpieces. Screens and/or additional cathodes are arranged in series or in parallel to key cathode. EFFECT: increased quality of machined articles. 5 dwg
