Abstract: A cutting belt comprises a guide bar system that includes a guide bar. The guide bar has a first end section, a second end section, and a central section between the first end section and the second end section. A first upper fluid channel is defined through the guide bar. The first upper fluid channel has an entrance opening in the first end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with a bottom channel. The second upper fluid channel has an entrance opening in the second end section of the guide bar and extends to the central section of the guide bar where it is in fluid communication with the bottom channel.

Abstract: A band saw is disclosed that includes a frame, a guide wheel, and a blade disposed around the guide wheel. A guide wheel chassis can be movably disposed on the frame, the guide wheel rotatably disposed on the guide wheel chassis. The band saw can include a blade tension adjustment assembly including a tensioning motor, wherein operation of the tensioning motor produces movement of the guide wheel chassis and the guide wheel relative to the frame to adjust the tension of the blade. A tension gauge can be positioned to determine a tension in the blade, and a controller can be communicated with the tensioning motor and the tension gauge, the controller operable to receive tension data from the tension gauge and control operation of the tensioning motor based on the tension data to control the tension of the blade.

Abstract: A band saw kit including a band saw and an angle guide. The band saw includes at least one wheel for supporting a saw blade, a motor operable to drive the blade to cut a workpiece, a frame, and a workpiece bumper coupled to the frame. The workpiece bumper includes a slot configured to receive the blade, a first engaging surface defining a first plane, and is configured to be generally perpendicular to the blade as the blade passes through the slot. An angle guide is configured to be coupled to the workpiece bumper and includes a second engaging surface for engaging a workpiece. The second engaging surface defines a second plane. A cut angle is defined by an angle between the second plane and the first plane when the angle guide is coupled to the workpiece bumper.

Abstract: A band saw vice assembly for securing a substrate for cutting includes a base that has a first plate coupled to and extending vertically from a first side. A first bar, which is hollow, is coupled to and extends perpendicularly from the first plate. A second plate is coupled to and extends perpendicularly from a sleeve that is positioned around the first bar. A first slot and a second slot, which are aligned and perpendicular to the base, are positioned in the first plate and the second plate, respectively. An actuator, which is operationally coupled to the sleeve, is coupled to and positioned in the first bar. The actuator is positioned to motivate the second plate toward the first plate to frictionally couple to a substrate to fixedly position the substrate. The first and second slots are configured to insert a blade of a band saw to cut the substrate.

Abstract: 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.

Abstract: A band saw includes a first blade guide assembly and a second blade guide assembly which guide the band saw blade through a cutting zone. The first blade guide assembly and the second blade guide assembly are each supported for pivotal movement about a pivot axis between a first angular position and a second angular position. At the first angular position, the first and the second blade guide assemblies hold the band saw blade at a first angle with respect to the wheel contact plane. At the second angular position, the first and the second blade guide assemblies hold the band saw blade at a second angle with respect to the wheel contact plane, the second angle being different than the first angle.

Abstract: A method for sawing a metal tube (3) or a hollow section is disclosed. The method includes using a band-saw machine, which has a stationary lower saw part (1), having a saw table (2) for securing the metal tube (3) or the hollow section to be sawn, and an upper saw part (4), which is movable in relation to the lower saw part (1) and which has a revolving saw band (5). The revolving saw band (5) penetrates the metal tube (3) or the hollow section via a feed motion (13) of the upper saw part (4), which is performed in relation to the lower saw part (1). For performing a saw cut, the revolving saw band (5) is guided through the metal tube (3) or the hollow section. The feed motion is carried out substantially counter to the force of gravity.
