<p>The invention relates to a pipe machining apparatus Pipe-machining apparatus with a cutting device, wherein the cutting device is movable relative to a pipe to be machined in an advancing direction (102) running radially with respect to the centre longitudinal axis of the pipe and in a cutting direction (101) running in the circumferential direction of the pipe, and wherein the cutting device has a tool holder (10) for fastening tools (40, 50) for machining of the pipe. In order, in a manner which is easy to realize but nevertheless effective, to be able to execute a plurality of machining steps in one operation using one pipe-machining apparatus, it is provided according to the invention a first tool (40) and a second tool (50) are fastened to the tool holder (10) in such a manner that, during the pipe machining, in which the cutting device moves relative to the pipe both in the advancing direction (102) and in the cutting direction (41) of the first tool (40) moves ahead of a cutting edge (51) of the second tool (50) both in the cutting direction (101) and in the advancing direction (102).</p> |
