This invention relates to the technical field of magnetorheological polishing, and discloses a magnetorheological polishing device and method with adjustable magnetic field strength. The device includes a polishing worktable, a first mounting groove with multiple mounting rings distributed from top to bottom on its inner wall, and multiple magnetic sheets fixed at equal intervals on the inner wall of each mounting ring. A toothed ring is fixed on the outer wall of a chuck, and a gear is rotatably connected to the inner wall of a second mounting groove. This invention uses a limiting mechanism to compress a container, thereby compressing and raising / lowering the support assembly within the first mounting groove. This increases the number of mounting rings surrounding the container, and consequently, the number of magnetic sheets surrounding the container and inducing magnetofluidity with the magnetic needles within it. This allows for appropriate adjustment of the magnetic field strength during the magnetorheological polishing process. This design, by changing the number of magnetic sheets surrounding the container to adjust the magnetic field strength of the magnetorheological polishing device, not only improves the polishing quality of workpieces made of different materials but also reduces the manufacturing cost of the polishing device.
