[0002] Special-shaped thin-walled housings are metal parts with complex shapes, which are often used in various industrial fields, such as automobile manufacturing, aerospace, etc. Due to their thin-walled characteristics and complex shapes, they often have burrs, which are protruding metal edges or thorns formed during the processing. Burrs not only affect the appearance of the housing, but may also cause unstable installation or hinder normal use, so they need to be removed in time.
