With the development of high-end equipment such as aviation, aerospace, and weapon systems, lightweight, high-strength, complex thin-walled parts are widely used. In the precision machining process of such thin-walled parts, due to the limitations of materials, tool path, process parameters, etc., it is inevitable that a large number of macro and micro burrs will be generated on the edges of the workpiece surface. These burrs have a bad impact on the normal operation, service performance, safety and stability, and service life of the equipment. At present, conventional deburring methods mainly include manual deburring, grinding deburring, chemical deburring, electrolytic deburring, etc., but because thin-walled parts in the aerospace field usually have thin walls, small shapes, complex geometric structures, and high surface quality, conventional deburring methods can easily destroy the surface state of thin-walled parts, and these methods also have the disadvantages of high production cost, low processing efficiency, high operation difficulty, and low degree of automation. Therefore, it is necessary to develop efficient burr removal processes and equipment.

In order to solve the above problems, a multi-station magnetorheological flexible deburring device suitable for improving the edge quality of thin-walled parts is proposed.
