METHOD OF PLANETARY INTERNAL GRINDING Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to internal grinding and can be used for finishing internal conical surfaces. According to proposed method, grinding wheel is set for rotation around its axis with planetary rotation and longitudinal feed at fixed workpiece. Grinding wheel is installed with position of its own axis of rotation at angle α relative to axis of its planetary rotation. Point of intersection of said axes is arranged at side of vertex of cone of machined part. EFFECT: improved quality and increased capacity at machining of conical surfaces, reduced heat stress and simplified design of device for implementing the method. 2 ex, 6 dwg
