High-speed high-precision electrochemical shaping of profile composite tools and machine parts (components)

摘要

A method of high-speed high-precision electrochemical shaping (HSHPES) of complex tools and machine components,which is based on impulse cyclic electrochemical dimensional machining in the flow of a neutral aqueous electrolyte,was developed. This tech nology allows one to process with maximum efficiency, high precision (up to several microns) and low roughness of the surface (10-100 run) hard and tough high-alloy steels,used in tooltnaking,dies and press molds.It can be applied to special alloys and titanium al loys for manufacturing of turbine blades, and to different composite materials,including intermetallic compounds,oxide-metal materials,hard alloys on the basis of carbides,nitrides,oxycarbonitrides of transition metals.
