METHOD OF HONING OF HELICAL GROOVES ON INTERNAL SURFACE OF ROTATION AND HONING HEAD INTENDED FOR ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: method includes removal of allowance from sections of every panel surface, namely, during forward movement of honing head allowance is removed from one side surface and from part of bottom adjacent to it. When honing head moves backward allowance is removed from other side surface and from part of bottom adjacent to it. Allowance is removed from bottom parts overlapping each other in width. Honing head has body, shank mounted for axial rotation relative to body, releasing cone, blocks with slots inclined to longitudinal axial plane of head through angle of elevation of machined groove helical line. Bars are mounted in slots for self-setting over circumference of body. EFFECT: enhanced machining process. 2 cl, 5 dwg
