Zusammenfassung:metal working, namely working deep holes in low-rigidity elongated parts, possibly in universal machine tools at assembling production. SUBSTANCE: apparatus includes boring bar and boring head with cutting tips; boring head is secured to working portion of boring bar. Guiding members are mounted in working portion of boring bar. Resonator of complex oscillations has spacing wedges and it is arranged in non-working portion of boring bar. Wedges are fixed by tightening screws and they are placed in double-start different-radius screw grooves with cone cross section. Use of such apparatus allows to increase accuracy of worked part, to enhance quality of worked surface, to provide stability of shapes and dimensions at using part. EFFECT: enhanced efficiency of working, operational reliability of tool. 4 dwg
