Abstract
Machine for ultrasonic abrasion machining of the type comprising an assem (1) supporting the parts (p) to be machined; a vibrating assembly (9) ending in a tool-holder (12) and adapted to drive the tool (8) with a reciprocal movement at ultrasonic frequency and to communicate these vibrations to an abrasive machining liquid; a system for the controlled descent of the tool towards the part to be machined, the attacking surface of the tool (8) being perpendicular to the axis of the tool-holder (12), so that the ultrasonic abrasion machining is carried out at the tool end; a device for regulating the downward movement of the tool; and, between the vibrating assembly (9) and a fixed frame (4), acousto-mechanical filters (20) disposed at longitudinal amplitude nodes (21, 22) of the vibrations, characterized in that an acousto-mechanical filter (20) is formed essentially of two concentric rings (23, 24) connected together by equidistant bridges (25), the inner ring (24) being deformable resiliently under the effect of the radial vibrations.
