Abstract: A 3D magnetorheological polishing device and a magnetorheological polishing fluid are provided. The 3D magnetorheological polishing device includes a container and a magnetic field generator. The container is disposed with an accommodation space to accommodate a polishing fluid and a workpiece that is to be polished. The container is disposed on the magnetic field generator and rotates synchronously with the magnetic field generator. The container and the magnetic field generator are capable of rotating in conjunction at a predetermined speed, such that the polishing efficiency is improved.

Abstract: A polishing system based on a non-Newtonian fluid and a polishing method thereof are provided. The polishing system includes a polishing device, a non-Newtonian fluid auxiliary device and a control device. The polishing device is able to move a work piece in a polishing container containing the non-Newtonian fluid with abrasives that cause the polishing action. The non-Newtonian fluid auxiliary device is able to manipulate the viscosity of the non-Newtonian fluid by varying the pressure, speed, vibration or ultrasonic frequency, which causes the abrasives to polish the work piece. The control device is used to optimize the polishing process by controlling how the polishing device moves the work piece inside the polishing container. In this way, by using the polishing method, the polishing system provided is able to polish a work piece with any three-dimensional shape.
