- a machine frame including a support device for supporting the metal workpiece to be processed wherein the support device comprises a vise including a stationary jaw and an adjustable jaw;
- a main carrier;
- a swivel support arranged on the main carrier above the support device, the swivel support defining a vertical swivel axis that extends through the support device;
- an intermediate carrier that is connected to the main carrier by means of the swivel support and can be swiveled about the vertical axis with the aid of the swivel support;
- and
- a saw frame including a bandsaw blade configured for cutting metal that runs in a guided fashion, said saw frame being movably supported on the intermediate carrier in such a way that the saw frame can be displaced or swiveled in a plane that extends parallel to the swivel axis;
- said stationary jaw of said support device defining a contact surface that includes the vertical swivel axis;
- and
- said main carrier having a lateral upright that is located adjacent to said support device and a cantilevered projecting beam mounted on said upright, and said swivel support being supported on said cantilevered projecting beam, outwardly of said lateral upright,
