  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Since the saw blades of a band saw machine and a circular saw machine are already well-known structures, description of the structure of the saw machines will be omitted. In addition, since the band saw blade and the circular saw blade as the saw blade have a well-known configuration, the case of the band saw blade is exemplified as the saw blade, and the relationship between the band saw blade and the rotating brush will be described.

  Referring to FIG. 1, in the present embodiment, a rotating brush 3 is disposed on the tooth tip side of a saw tooth 1 </ b> T in a band saw blade 1 as a saw blade. That is, the tooth tip side of the saw blade 1T in the band saw blade 1 is orthogonal to the traveling direction of the band saw blade 1 (arrow A direction) and the cutting direction of the band saw blade 1 relative to the workpiece (vertical direction in FIG. 1A). A direction shaft (drive shaft, brush support shaft) 5 is disposed, and a brush mounting shaft 7 provided at a tip portion of the shaft 5 is integrally provided at a central portion of the brush base 3A of the rotary brush 3. The center bush 9 is fitted and detachably attached by a mounting nut 11.

  The center bush 9 is a bush for attaching the rotating brush 3 to the brush attachment shaft 7 in the shaft 5, and the center bush 9 is provided with an attachment hole 13 for fitting with the brush attachment shaft 7. ing. The axis 13S of the mounting hole 13 is inclined by an angle α with respect to the central axis 3S of the rotating brush 3. The intersecting position O of the shaft center 13S and the center shaft 3S is set to a substantially center position of the shaft center length of the rotating brush 3.

  With the above configuration, when the shaft 5 is rotated in a state where the rotary brush 3 is fixed to the brush mounting shaft 7 of the shaft 5, the mounting hole 13 provided in the center bush 9 is inclined with respect to the central shaft 3S of the rotating brush 3. Thus, the rotation plane of the rotary brush 3 (plane orthogonal to the central axis 3S) swings with the intersection position O as the center position (swing center). Therefore, the outer peripheral surface (contact surface) 15 of the rotary brush 3 that contacts the saw blade 1T in the saw blade 1 is one end of the outer peripheral surface 15 according to the rotation of the rotary brush 3, as shown in FIGS. The contact position is gradually changed from the side 15A to the other end side 15B and vice versa.

  That is, since the rotary brush 3 rotates while oscillating on the plane of rotation, the outer peripheral surface of the saw blade 1 in contact with the saw blade 1T reciprocates across the position of the saw blade 1T. It acts so as to wipe off the chips adhering to 1T, and can effectively remove the chips adhering to the saw blade 1. In other words, the contact position of the saw blade 1 with respect to the outer peripheral surface of the rotary brush 3 is a mode that meanders relative to the outer peripheral surface of the rotary brush 3.
