Band saw machine

A band saw machine for cutting a cut portion of a workpiece set at a cutting position on a feed direction while running an endless band saw blade, the machine comprising:

• a base that has a cutting fluid reservoir for collecting cutting fluid at an upper portion thereof;
• a saw blade housing that is provided at the base movably in an up-down direction;
• a pair of saw blade wheels that are provided rotatably in the saw blade housing to support the band saw blade and distanced from each other in a feed width direction perpendicular to the feed direction, the band saw blade being wound around the saw blade wheels in a tilted-down state so as to regulate a maximum cut length of the workpiece by a diameter thereof, and the pair of saw blade wheels is positioned in a plane that extends both parallel to the feed direction and perpendicular to the up-down direction;
• a saw blade guide that guides the band saw blade so as to make tooth ends of the band saw blade perpendicular to the workpiece at the cutting position;
• a downstream main vise that is provided on a downstream side of the cutting position on the base and has a pair of downstream main vise jaws for clamping a product correspondent portion of the workpiece;
• and
• a discharge table for discharging a product to an outside of the cutting fluid reservoir, wherein
• a working-side running area of the band saw blade running through the cutting position and a working-opposite-side running area of the band saw blade running at a position distanced from the cutting position in the feed direction are positioned within the cutting fluid reservoir in a plan view, the working-side running area being positioned upstream from the working-opposite-side running area along the feed direction,
• an upstream end of the discharge table is positioned on a downstream side from a wheel center line connecting rotational centers of the pair of saw blade wheels,
• the band saw machine comprises a product feed mechanism that feeds the product cut out from the workpiece to a side on an upstream end of the discharge table,
• the base including, on a downstream side of the cutting position and along the feed direction, a downstream feed table for supporting the workpiece movably in the feed direction,
• the discharge table includes a discharge chute pivotably mounted at one end to the downstream feed table,
• wherein the discharge chute is configured to pivot at the one end from a first position at which the discharge chute extends coplanar with the downstream feed table to a second position at which the discharge chute is inclined downwardly with respect to the downstream feed table,
• the discharge table further including a discharge roller conveyor including drive rollers that are aligned in the feed direction at intervals and can be rotated by a discharge actuator, and
• a portion of the discharge roller conveyor on a side of an upstream end thereof is located on an upper side of the discharge chute, and is movable in the up-down direction.
