Abstract
A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade provided on the band-saw machine in a direction of a workpiece by a band-saw blade guiding apparatus; and applying vibrations to the band-saw blade in a cutting direction to the workpiece so as to perform cutting of the workpiece by a vibration applying unit provided on the band-saw blade guiding apparatus.
Claims2
A band-saw machine, comprising:
- an endless band-saw blade having a plurality of teeth;
- a plurality of band-saw blade guides that guide tooth tips on the band-saw blade toward a workpiece to be cut, one of the band-saw blade guides being movable in a direction towards and away from at least one other band-saw blade guide;
- and
- vibration applying units provided on the plurality of band-saw blade guides to apply vibrations to the band-saw blade in a cutting direction with respect to the workpiece, wherein
- the respective vibration applying units are coupled to each other via a power transmission unit,
- and an amplitude of the vibrations is smaller than a height of the teeth.

A band-saw machine comprising:
- an endless band-saw blade having a plurality of teeth;
- a band-saw blade guiding apparatus that is adapted to guide tooth tips on the band-saw blade toward a workpiece to be cut;
- a swinging arm that is adapted to swing in a vertical direction;
- a pressing rod having an upper end contacting an end of the swinging arm;
- and
- a backup holding member provided on the band-saw blade guiding apparatus, and contacting a lower end of the pressing rod,
- wherein, when the swinging arm swings in the vertical direction, the backup holding member is pressed towards the band-saw blade by the pressing rod to apply a vibration to the band-saw blade in a cutting direction with respect to the workpiece,
- and an amplitude of the vibration is smaller than a height of the teeth.
