FIELD: metallurgy.SUBSTANCE: invention relates to cermet cutting, particularly, to sintered porous cermet surface ply forming. Said material can be used for production of parts from antifriction materials used as self-lubing antifriction bearings incorporated with speedometers, starters, wipers, window raisers, borehole pumps, household hardware. Proposed method comprises removal of the part main machining allowance. Thereafter, the surface is subjected to effects of chemically active solution fed to cutting zone from activator tank filled with the solution. 28 V 2.4 A electric current is fed there through to allow the electrochemical etching.EFFECT: better machinability.1 dwg |
