ABSTRACT:
A band saw machine is provided with a cutting head that carries the endless saw blade. The cutting head can be swung from a vertical cutting plane into a horizontal cutting plane. Limits can be made in the feeding stroke of the cut and the return travel. A workpiece feeding and clamping vice is rotated about a horizontal axis. The combined positioning capability of the band saw blade and the workpiece vice allows difficult compound angular cuts to be made in the workpiece. The endless run of the blade is angled upwardly and outwardly away from the workpiece to provide additional clearance for cutting deep workpieces. Powered feed rolls advance the workpiece against a gauging stop to determine a predetermined length to be cut. The vice is then closed to hold the workpiece during cutting. Supplemental supports hold the rearward end of the workpiece during feeding and cutting. Blade guides are spaced for accomodating both small and large width blades.
