Band saw
A band saw is includes a driving wheel and a driven wheel rotatably provided at a saw housing; an endless saw band made to run around the driving wheel and the driven wheel; and a plurality of saw band guiding devices for directing and guiding cutting edges of the saw band toward a direction of a workpiece to be cut. The saw band guiding devices are constructed to be movable in directions where one of the guiding devices gets closer to and away from another of the guiding devices, wherein each of the saw band guiding devices includes vibrating means for vibrating the saw band in a cutting direction relative to the workpiece. A pressure member holder including a plurality of pressure rollers or a pressure member for pressing a back surface of the saw band is provided in each of the saw band guiding devices.
Saw band guiding device
A saw band guiding device is comprised of a fixed insert holder comprising a fixed insert guide at a tip end portion of the fixed insert holder, the fixed insert guide guiding one side surface of a saw band; and a movable insert holder comprising a movable insert guide at a tip end portion of the movable insert holder, the movable insert guide being opposed to the fixed insert guide and guiding another side surface of the saw band, the movable insert holder being rotatable relative to the fixed insert holder, wherein the movable insert holder is provided to be regulated in directions where the movable insert holder gets closer to and away from the fixed insert holder so as to regulate a saw band guiding surface of the fixed insert guide and a saw band guiding surface of the movable insert guide to be parallel with each other.
SAW GUIDE AND METHOD OF USING SAME
A saw guide can include pivotally connected arcuate sections having a plurality of slots formed therein to receive and guide saw blades as they cut a workpiece, such as a pipe or tube. The slots are of varying width so that the saw guide can be used with different saws. For example, the saw guide can include a first slot sized to receive and guide the blade of a reciprocating saw, and a relatively narrower second slot, sized to receive the blade of a portable band saw. The saw guide can include a locking mechanism to securely hold the saw guide on the workpiece, and a stopping mechanism for preventing the saw blade from cutting into the saw guide.
ANTI-VIBRATION METHOD OF BAND SAW BLADE IN BAND SAW MACHINE AND ANTI-VIBRATION ARRANGEMENT
An anti-vibration arrangement for a band saw blade in a band saw machine, which is constructed to cut a workpiece by shifting the endless band saw blade running in a circulating manner to a cutting direction, wherein nozzles are provided for injecting high-pressure cutting liquid toward each side face of the body of the band saw blade on the entering-side where the band saw blade enters into a cut groove of the workpiece formed by the band saw blade in the cutting process of the band saw machine.

Saw device and method for sawing a workpiece
In order to improve a saw device with a feed axis for a workpiece to be sawed, with a first saw unit to saw the workpiece in a first sawing plane extending transversely to the feed axis and with a second saw unit to saw the workpiece in a second sawing plane extending transversely to the feed axis, with a central device region arranged between the sawing planes, with a front device region arranged in front of the first sawing plane, viewed in a feed direction, and with a rear device region arranged behind the second sawing plane, viewed in the feed direction, in such a way that as high a cutting efficiency as possible can be achieved, it is proposed that the saw device comprises at least two transport mechanisms arranged in different device regions to transport different workpiece portions along the feed axis.
PANEL SAW
A panel saw including: a housing supporting a motor-driven spindle that moves in reciprocation; a blade coupled to the spindle; a stabilizer extending away from the housing and spaced apart from the blade; a terminal guide structure coupled to a distal end the stabilizer, wherein the terminal guide structure comprises: one or more lateral guide surfaces configured to support the blade in a desired cutting plane; a rear support configured to support a rear edge of the blade; or a combination thereof.
TIMBER PROCESSING AND FIREWOOD SPLITTING MACHINE
A timber processing and firewood splitting machine is provided, comprising a self-standing bearing frame for being placed on the ground, a conveying unit arranged in one terminal area of said bearing frame and configured to convey timber of a pre-determined diameter in the longitudinal direction of said bearing frame, a cutting unit suitable for cutting said timber to separate longitudinal sections of a pre-determined length, a guiding unit for guiding each timber section in said longitudinal direction and along a geometric axis (10) towards a working area (5), and a splitting unit and supporting assembly for supporting firewood pieces upon being split apart from the rest of said longitudinal section of the timber.
Handheld band saw
A handheld band saw includes a housing assembly including a battery pack mounting portion for mounting a battery pack, a rotating wheel assembly at least partially disposed in the housing assembly and including a first rotating wheel and a second rotating wheel, where the first rotating wheel and the second rotating wheel are configured to be substantially symmetrical about a midplane, an electric motor disposed in the housing assembly and capable of driving one of the first rotating wheel and the second rotating wheel to rotate, a fan which is capable of generating at least one airflow in the housing assembly, and a control circuit board disposed in the housing assembly.
