摘要：Vibratory drilling and other machining operationsare known to be very effective when vibrations of highfrequency (f = 20 - 50 kHz) and small amplitude (A = 5 -20 μm are generated in the direction of feed [1-5]. Then:1) rigidity of a technological system increasesand cutting forces decrease, while accuracy and efficiencyof processing rise;2) deep holes of relatively small diameter can bedrilled throughout without repetitive insertion and with-drawal of a drill from drilled hole cycles as it is common inconventional drilling;3) chips are shattered into small segments, thuseasing their removal from the hole.In technological devices of vibratory drilling highfrequency vibrations may be excited by piezoelectric gene-rators. However, these devices are relatively expensive andthey can be economically used only when production iseither fairly large or specific (e.g. airspace or military in-dustry). In ordinary practice of mechanical processing,when producing small serial items, many advantages ofvibratory drilling may be achieved by applying simpler andcheaper technological devices. Authors of this article pro-pose generation of torsional vibrations in a drilling opera-tion with a generator of simple design. The operationalprinciple of this generator is based on the interaction ofpermanent magnets placed on driving and driven links[6, 7].
