摘要： 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.

摘要： The present invention discloses an automatic high-shear low-pressure force-controlled grinding device for a complicated curved surface and a machining method thereof, which belong to the field of complicated curved surface grinding technologies of difficult-to-machine materials. The device comprises a base, columns, an industrial robot, an electrical spindle, a force-controlled floating work holder, a workpiece chuck, a grinder plate, a six-dimensional force sensor, a rotary table, a triaxial precision displacement table, a safeguard hood, a safety door, and a pedestal. The grinder plate comprises a grinder plate substrate, a press plate, a lining plate, and an abrasive layer. Each module is effectively communicated, and a control system collects and processes signals as well as transmits commands to achieve automatic force-controlled grinding of the complicated curved surface. The abrasive layer of the grinder plate generates the shear thickening effect; so, the material can be removed in a high-shear low-pressure grinding manner.
