摘要： The invention concerns a pipe-cutting and chamfering arrangement for thin-walled pipes, the arrangement comprising a machine tool (2) with a cutting and chamfering tool (15, 16) and a clamping device (1) for cutting a pipe and chamfering the point of separation. The cutting and chamfering tool (15, 16) is guided about the pipe (10) which is clamped between the jaws (7, 8) of the clamping device (1). In order to compensate and prevent deviations in the circular periphery of the pipe (10), it is pressed into a round shape when it is clamped in place. The tools - a saw blade (15) and a milling cutter (16) - are disposed closely adjacent each other on a common shaft (17). The teeth (20) of the saw blade (15) are widened on one side and cover the outermost edge (19) of the milling cutter (16), this edge not being used during the chamfer process.
