TOOL FOR FINISH MACHINING OF HOLES Russian patent published in 1998 - IPC

FIELD: metal machining by cutting and plastic surface deformation; may be used in finish-machining of internal surfaces of holes of machine components. SUBSTANCE: tool has coaxially installed grinding wheel with starting taper of variable cross-section for burn-free deep grinding and cylindrical body deforming members located adjacent to one another. Grinding wheel and deforming members are installed at an angle α relative to rotation axis which is selected in accordance with inequality 0 <α< arctg (H/D), where H is height of grinding wheel, m; and D is diameter of grinding wheel, m. EFFECT: higher quality and free of burning-on of hole grinding due to periodic combined and successive machining of treated surface by grinding wheel and rotation with axially displaced cutting and deforming sections, and reduced main time of machining. 4 dwg
