FIELD: technological processes in machine engineering, namely working precise holes. SUBSTANCE: boring tool has cutting blade and guide mounted in groove of its body and having flat bottom surface. In order to provide notch-free removal of tool out of worked opening it is provided with stop and spring. Guide may move along tool axis. Above mentioned groove is arranged in side diametrically opposite relative to side of cutting blade; bottom of groove is inclined relative to axis in direction of feed motion. Stop is connected by means of spring with guide and it is fixed in groove with possibility of controlling its axial position and with possibility of limiting terminal rear position of guide. EFFECT: improved design. 3 dwg |
