FLEXIBLE DISCONTINUOUS TOOL FOR HOLE MACHINING Russian patent published in 2003 - IPC

FIELD: abrasive machining of holes in machine parts. SUBSTANCE: tool has body in form of bushing with through radial slots and carrying part with working member in form of flexible metal strip. The latter is rolled into ring with formation of corrugations. External parts of corrugations form discontinuous cylindrical surface. Internal parts of corrugations are fastened in said slots. EFFECT: higher accuracy and efficiency of machining, reduced process heat-release rate due to discontinuous cutting zone and possible control of radial feed, simplified tool design. 4 cl, 3 dwg
