BORING TOOL Russian patent published in 2005 - IPC

FIELD: technological processes in machine engineering, namely operations for removing tool out of worked opening without use of mark.

SUBSTANCE: tool includes movable guide spring-loaded in axial direction and arranged in lengthwise groove of body. Said groove has bottom with flat surface inclined relative to tool axis. Guide is mounted with possibility of sliding on bottom of groove and it engages by its one end surface with stop arranged in said groove with possibility of regulating its axial position. In order to enhance accuracy at working thin-wall parts, groove is arranged at side of cutting blade and it is spaced from blade by minimally possible distance along perimeter of worked opening. Surface of groove bottom is inclined relative to tool axis in direction opposite relative to that of working feed of tool. Stop limits boundary front position of guide in groove of tool body.

EFFECT: enhanced accuracy of working.
