摘要:
A band saw machine includes a base having a cutting fluid reservoir, a saw blade housing movable in an up-down direction, a pair of saw blade wheels around which a band saw blade are wound, a downstream main vise having a pair of downstream main vise jaws for clamping a product correspondent portion of the workpiece, a discharge table for discharging a product to an outside of the cutting fluid reservoir, and a product feed mechanism that feed the product cut out from the workpiece to a side on an upstream end of the discharge table. A working-side running area of the band saw blade and a working-opposite-side running area of the band saw blade are positioned within the cutting fluid reservoir, and the upstream end of the discharge table is positioned on a downstream side from a wheel center line connecting centers of the pair of saw blade wheels.

In the process of holding a non-toothed section of a band saw blade (5) between a fixed insertion block (9) and a movable insertion block (15) included in a band saw blade guide device, the movable insertion block (15) is moved while a return allowing unit (33) included in an insertion block moving unit (21) is held in a returnable state, the insertion block moving unit (21) configured to move the movable insertion block (15) toward the fixed insertion block (9). The band saw blade (5) is firmly held between the fixed insertion block (9) and the movable insertion block (15). Whereafter, the entirety of the insertion block moving unit (21), including the return allowing unit (33), is fixed in an immovable state by a mechanical fixing unit (45). In this fixed state, a clearance between the fixed insertion block (9) and the movable insertion block (15) is kept at an appropriate clearance corresponding to a thickness of the band saw blade (5) by a return allowing action of the return allowing unit (33).

In a method for marking on a surface of a work, kept is a state where an end of a rotating tool for marking is contacted with a surface of the work, and a rotation of the rotating tool is started at the same time when a relative movement of the work in an X-axis direction and/or in a Y-axis direction relative to the rotating tool is started. According to the above marking method, a width of a marked line can be made constant over its entire length.

A band saw blade includes left and right set teeth which are set in right and left directions with respect to a running direction of the band saw blade, and a straight tooth which is not set. A ridge line (9) at a tip of each of the set teeth (3, 5) and the straight tooth (7) is formed into a convex curved line protruding most at a central portion in a thickness direction of the saw tooth (3, 5, 7). The ridge lines (9) at the tips of the left and right set teeth (3, 5) and of the straight tooth (7) are continuous with one another when viewed from the running direction of the band saw blade (1). A height difference between the ridge lines (9) of the saw teeth (3, 5, 7) is in a range of 0.02 mm to 0.1 mm. Meanwhile, a height difference between an inner corner portion (3B, 5A) of each of the left and right set teeth (3, 5) and the central portion in the thickness direction of the ridge line of the straight tooth (7) is in a range of 0 mm to 0.03 mm.

A horizontal band saw machine for cutting a workpiece by an endless band saw blade includes a vise mechanism provided on a downstream side of a cutting position and having a pair of jaws, a vertically-movable cutting head, a pair of saw blade wheels provided rotatably on the cutting head, the band saw blade looped over the pair of saw blade wheels, a saw blade guide mechanism having a pair of saw blade guides that are suspended from the cutting head, a contact guide attached to the other of the pair of jaws, a coupling bracket connected to the other of the pair of saw blade guides to locate a distal end thereof below the other of the pair of saw blade wheels, and a follower member provided at the distal end of the coupling bracket to contact with the contact guide slidably. The contact guide and the coupling bracket are configured to move one of the pair of saw blade guides until the follower member contacts with the contact guide when the band saw blade is fed circularly in a state where the band saw blade is clamped by the one of the pair of saw blade guides.
