Results of researches of electrochemical machining of Alnico and Х25К15 magnetic alloys are presented. Problems of conventional machining processes (cutting, milling, drilling and grinding) use a sharp cutting tool are noted. The expediency of use NaNO3 of electrolytes at high-speed anodic dissolution of magnetic work piece surfaces has been demonstrated. Agency of chemical and phase composition of magnetic alloys on a landform of a surface after the ECM in нитратных water electrolytes is installed. The gained results of experimental researches allow to control parameters of a technological process with given accuracy and speed of electrochemical machining of parts.
