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). The revolving saw band (5) via 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.

A device and method are disclosed. An embodiment of a sliding sled for use on a saw table includes a flat plate, adjustable guide fences on the flat plate at a fixed pivot end to create an oblique relative to the saw table, an indexing system including angle indicators to set the angles of the adjustable guide fences, roller bearings on the bottom side of the flat plate for riding on the ACCU-SLICE rail, and a sawdust shield to keep sawdust off the roller bearings and ACCU-SLICE rail. Guide fences may have a fixed pivot end and a movable end and a locking bolt to temporarily fix the movable end at a desired position on the plate. The movable end of the adjustable guide fences may align with the angle indicators when the angle of the adjustable guide fence relative to the cutting plane corresponds to the angle indicators.

A dust collection structure of the band saw machine includes a dust collection member and a combining member. The dust collection member has a seat connected to a worktable, a tube connected to the seat and having a tube hole communicating with a seat hole, and a slot provided at the seat and the tube and penetrated by a saw band and communicating with the seat hole and the tube hole. The combining member is used to fix the dust collection member to the worktable through the seat. By directly installing the dust collection member on the worktable, sawdust directly falls into the seat hole and the tube hole to be sucked away. The present invention has a simple structure and convenient and fast installation. This improves dust collection efficiency and solves the known issue of sawdust easily scattering and accumulating on the worktable.
