A reduction motor is fixedly connected with an aluminum alloy section frame, an output shaft of the reduction motor is fixedly connected with a transmission shaft through a coupler, the transmission shaftis fixed by an upper deep groove ball bearing and a lower deep groove ball bearing, a Z-direction outer rotor module is fixedly connected with the upper end of the transmission shaft, a container module is fixedly connected with the upper portion of the aluminum alloy section frame, a polishing solution container of the container module is positioned in the Z-direction outer rotor module, and a polishing tool is placed in the polishing solution container. The polishing device has the advantages that polishing of the inner cavity with complex curved surface is realized, due to the design of the outer rotor module structure, the influence of a magnetic field generated by the reduction motor on the polishing tool is reduced, and the polishing precision is further improved; and a precise lifting platform controls the distance between the polishing tool and a workpiece, so that the flow rate of the polishing solution and the pressure of the polishing tool on the workpiece can be accuratelyadjusted, and the application range of the device is quite wide.

The dynamic magnetic field generated by the electromagnetic coil is mainly the uniform magnetic field generated by the Helmholtz coil and the uniform magnetic field generated by the Maxwell coil. The method of attitude adjustment realizes the control of the shape and motion of the micro-robot, but due to the limitation of the electromagnetic field, the magnetic field space generated by it is small, and the space for the micro-robot to move is small

When a single permanent magnet is used to achieve control, the magnetic field strength generated by it can stabilize the operated object. For example, the document "Control of Untethered Magnetically Actuated Tools using a Rotating Permanent Magnet in any Position" proposes a permanent magnet through rotation The method of forming a rotating magnetic field to drive the tool to rotate can be found from the experimental process that the manipulated permanent magnet can rotate close to the surface of the workpiece stably and at a high speed. It can ensure the rotation on the surface of the workpiece, and cannot achieve complete suspension rotation
