Abstract
FIELD: machine engineering, namely finish working of openings.
SUBSTANCE: method comprises steps of working surfaces of openings by boring and surface plastic deforming with use of combination type tool to which ultrasonic oscillations are imparted. Said combination type tool includes cutting and deforming members arranged mutually opposite in wave-guide and having working portions arranged in planes of maximum oscillation shifts. Apparatus includes ultrasonic oscillation system, cutting and deforming members. Ultrasonic oscillation system is in the form of two piezoelectric members and two metallic oscillation frequency reducing cover plates arranged successively and acoustically coupled one with other. One of said cover plate operates as wave-guide.; Boundary part of wave-guide is branched for forming two tips supporting cutting and deforming members arranged mutually opposite and having working portions arranged in plane of maximum oscillation shifts.
EFFECT: enhanced efficiency of working, improved quality of worked surface.
