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.

A band saw machine for sawing metallic workpieces, having a lower saw part and an upper saw part with two carrying wheels mounted therein, and a saw band that revolves with a cutting motion around the wheels that passes through a cutting region. A feeding device attached to the lower saw part feeds workpieces to the cutting region and/or into a sawing plane, in which the cutting region of the saw band is moved in a saw advance motion. The feeding device has a movable holder for detachably fastening the workpiece, and the holder, starting from an initial position, is movable both with translational and rotational motions. The saw band is guided through the cutting region, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. Here, the workpiece is preferably turned by the holder such that its upper side faces downward.

A profiling saw with band knife loop take-up and payoff compensation includes an endless circulating band knife which is guided around a plurality of band knife pulleys so the take-up and payoff adjustment is provided of the loop circulation path shape. The take-up and payoff system operates to move a pulley in the vertical plane for allowing the band knife to maintain its cutting orientation during movement and providing for more rapid and precision cuts into a workpiece.

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.

The present disclosure provides for an apparatus for using continuous, preferably smooth, bandsaw blades to cut a substrate. The current disclosure also discloses using the same for preparing a safe and efficient method for cutting substrates into rolls.

An automated saw for assessing an uncut meat and calculating a one or more cutting depths and cutting a one or more cut portions. The automated saw comprises a bandsaw blade, a controller, a visual sensor and a positioning system. The positioning system comprises a pusher and a tray configured to move the uncut meat relative to the bandsaw blade. The tray is configured to hold the uncut meat. The pusher is configured to slide the uncut meat through the tray. The positioning system is configured to move the tray in a first horizontal direction and a second horizontal direction relative to the bandsaw blade. The uncut meat comprises a first end and a second end. The first end of the uncut meat comprises a surface area and a diameter.

A method and an apparatus for manufacturing a stepped member are provided. An intermediate portion of a shaft workpiece is radially enlarged while being compressed in an axial direction by applying alternating load to the intermediate portion in a direction intersecting the axial direction in a state in which pressure that compresses the shaft workpiece in the axial direction is applied to both ends of the shaft workpiece. The enlarged intermediate portion of the shaft workpiece is cat in a direction perpendicular to the axial direction so that the shaft workpiece is divided into two stepped members. Each of the stepped members has a shaft portion and a head portion provided at an axial end of the shaft portion, and the head portion has a larger diameter than the shaft portion.

A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.
