ABSTRACT:
The known traveling steel pipe cutting machine of a milling type, which cuts a pipe while traveling in synchronism with a pipe manufacturing speed, is improved so as to facilitate the calculation of positional loci and the control of a milling cutter, to increase a rigidity of the machine and a life of the cutter, and to also make it possible to cut even a pipe having an asymmetric cross-sectional shape under the same set of operating conditions. A plurality of cutter heads each include a milling cutter, and are each supported and linearly fed in biaxial directions by respective guides and feed drive motors. A clamping device is positioned in the proximity of the milling cutters for holding and fixing the pipe. The cutter heads and the clamping device are disposed on a traveling truck. The machine is also provided with a control device for rotationally controlling the feed drive motors for moving the cutter heads on the basis of input data representative of cutting conditions such as a shape and dimensions of the pipe.
