Abstract

See full text

A controllable magnetic field-assisted finishing apparatus for an inner surface and a finishing method are provided. The apparatus includes a housing, ball screw mechanisms, a workpiece, a centering clamp, a connecting plate, a magnetic field generating device, a chuck clamp, a precise displacement platform and a base. The magnetic field generating device includes electromagnetic coils, coil connecting plates, a magnetic yoke, nuts, springs and bolts. The magnetic field generating device dynamically adjusts a distance from the magnetic yoke to the outer surface of the workpiece through the springs. The movement tracks of the magnetic finishing medium are controlled by the formed rotation of the magnetic field, the finishing action force dynamic-adjustment, the optimization of the machining form of the magnetic finishing medium in collaboration with the rotation of the chuck clamp and the feed movement of the precise displacement platform.
