With the rapid development of China’s steel market, the demand for steel pipes and the requirement for steel precision are also rising. Pipe end chamfering is the primary process of welded pipe forming, and the chamfering machine is the most basic equipment in the machining line. However, with the continuous increase of diameter and wall thickness of steel pipes, the traditional flat head chamfering machine has been unable to meet the market demand, and the contradiction between the growing demand for steel pipes and the outdated processing technology of chamfering machine is becoming more and more significant.Therefore, the new type of milling head chamfering machine researched in the paper will be of great significance to solve the contradiction.The introduction of the milling head chamfering machine for steel pipes in this paper can be mainly summarized as the following: first, based on the processing technology and the mechanical structure of traditional flat head chamfering machine and combined with the processing requirements of large caliber and wall thickness, the original single turning motion has been improved to two independent rotation systems of milling cutter rotation and revolution motion models. In addition to copying devices, the turning processing has been improved to milling processing. Compared with the traditional flat head chamfering machine,the new type of milling head chamfering machine has reduced the cutting force and power in the turning process, at the same time, it has enlarged processing range, enhanced the stability in the process, and improved processing accuracy. Second, in accordance with the maximum diameter and wall thickness of steel pipes, the design description of the full automatic multifunctional of the milling head chamfering machine is described in detail. At the same time, the processing range, the selection of tools and motors are also illustrated by detailed calculation. Third, 3D solid modeling for the milling head chamfering machine is formed by applying Solidworks 3D software, and the stress analysis and modal analysis for the key transmission shaft are conducted by using Ansys. Forth, closed-loop control principle of the new type of milling head chamfering machine is simply introduced, and the source and eliminating measures of the interference source in the machining process are illustrated as well. Fifth, based on the conclusion of the characteristics of the new milling head chamfering machine researched in the paper, it proved that the new milling head chamfering machine plays a positive role in the improvement of pipe chamfering process technology. In addition,the inadequacy of new type of chamfering machine structure is also pointed out, which provides direction for future development.
