Date Nov. 29, 1990.The device for ultrasonic machining of articles in a liquid medium comprises two groups (2, 3) of acoustical-electrical transducers (4) arranged on an elastic element (7), filled with a liquid medium (8), in staggered order at a predetermined distance from articles being machined. The acoustical-electrical transducers (4) of the group (2) are connected to the output of an ultrasonic generator (1). The acoustical-electrical transducers (4) of the group (3) are connected to the output of the ultrasonic generator (1) through a phase-pulse modulator (5) connected to a saw-tooth voltage generator (6).
