Chamfering machine is the special equipment for steel pipe end processing. At present the traditional chamfering machine processing quality to meet the market requirements, while imports chamfering machine price is too high, and the service cycle is long, therefore, r&d processing quality and production capacity of meet the practical needs of new domestic chamfering machine is imminent. This article by "steel flat chamfering production line of research and development" for background, the working principle of steel pipe chamfering, the overall scheme of the chamfering machine design; On the mechanical structure especially influence the machining accuracy of ponents, namely the knife dish and studied clamping device and make a detailed design. Therefore, from the domestic and foreign typical chamfering machine, expounds the structure of the chamfering machine arrangment scheme, power transmission mode, clamping device type, servo cutting head design and the design of control system technology development situation. On the analysis of the advantages and disadvantages of each pared, and points out that with the pipe production for high
