Abstract: A vertical band saw machine in which a carriage assembly is mounted for pivoting on a base by rotational pivot points. Pivoting of the carriage assembly enables the band saw machine to make miter cuts to a workpiece. The head frame of the band saw machine travels on a guide on the carriage assembly and moves only in the direction of the plane of cut. A vise assembly is preferably attached to the carriage assembly and pivots with the carriage assembly for keeping the vise assembly close to the line of cut at all times, regardless of carriage assembly orientation. A driving wheel and driven wheel are attached to the head frame and may be tilted with respect to the head frame.
