The invention relates to a method for sawing a metal tube 3 or hollow section using a band-saw machine which has a stationary lower saw part 1 having a saw table 2 for placing and fixing a metal tube 3 to be sawn, and an upper saw part 4 which is movable in relation to the lower saw part 1 and which has a revolving saw band 5, wherein the revolving saw band 5 by means of a feed motion 13 of the upper saw part 4, which is performed in relation to the lower saw part 1, penetrates the metal tube 3 and, for performing a saw cut, is guided through said metal tube 3. The feed motion is carried out substantially counter to the force of gravity. |
