Abstract: A method for manufacturing a bandsaw blade provided at the top of the teeth with cutting tips made of a hard material, includes the steps of: offsetting to the left and right saw teeth constituting left and right offset teeth; forming the saw teeth constituting the left and right offset teeth to a smaller tooth height than that of the saw teeth constituting straight teeth; and grinding cutting tips provided to the top of the left and right offset teeth subsequent to the offsetting step, and machining the edge lines at the top of the left and right offset teeth so that the lines are orthogonal to the travel direction of a bandsaw blade and the cutting direction of the bandsaw blade.
Abstract: Disclosed is a main body vise device (7) in a band saw machine, characterized in that: a movable main body vise body (33) is provided to a main body vise bed (31); an upstream movable vise jaw (37) is provided integrally to this main body vise body (33), while a downstream movable vise jaw (41) is movably provided on a downstream side of the main body vise body (33); a first pressing/biasing module (43) capable of advancing and retreating the main body vise body (33) is provided; and a second pressing/biasing module (45) capable of advancing and retreating the downstream movable vise jaw (41) independently of the upstream movable vise jaw (37) is provided.
