Development of burr-cleaning in domestic and internationl is analyzed. Process principle, method and construction are considered synthetically, the suitable and reliable project is drafted. The inner burr –remove equiment is designed in detail.Compared with the traditional design, this equipment is possessed of high work efficiency and traits of simple and credible operation and so on. It can be used to cut the inner and outer burr syncchronously, and the effect is good. In the detailed structure design, the Incline and Screw transmission are used ,which make the whole equipment creative and simple.
