A saw with a monitoring and safety system that utilizes vision and sensors designed to provide user feedback on safety and training. The saw having a wheel formed of an anodized main body with a non-anodized surface extending along the circumference of the groove of the wheel. The saw having low inertial energy design to stop the blade without mechanically grabbing the blade assuring multiple points of safety detection and triggering. The saw having an automatic guard to protect the user from slipping and hitting the blade even when the saw is not running. The saw being connected to a cloud based system that enables a safer ecosystem and cross statistic sharing of safety parameters.

A shoe for a band saw includes a block for coupling to the band saw, the block having an aperture, a locking ball disposed in the aperture, a body including a first surface for engaging a workpiece and an opposite surface having plurality of recesses, and a locking rod coupled to the block and movable between a first position and a second position. The locking ball is received in one of the plurality of recesses of the body when the locking rod is in the first position such that the body is fixed relative to the block, and the body is movable relative to the block when the locking rod is in the second position.

A cutting-angle adjustable bandsaw is provided with a base, a first mounting seat, a second mounting seat, a first saw table, a second saw table, a first drive unit, a second drive unit, a bandsaw unit and an adjustment unit. The first and second drive units can make the first and second saw tables move to different horizontal planes, so as to adjust the band blade riding between the drive wheel and the assistant wheel to an inclined position, so that the cutting angle of the band blade is changed to reduce the contact area between the band blade and the object to be cut.

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.

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.

A bandsaw makes simultaneous, spaced-apart cuts in hard or soft materials with a single bandsaw blade. The invention is ideally suited to cutting spaced-apart parallel surfaces to form support blocks, however, different embodiment may be controlled or programmed to make parallel or non-parallel cuts at varying angles. The single bandsaw blade rides on circular wheels on both sides of a gap or passageway, such that a first portion of the blade crosses the passage along a first, upper path, and a second portion of the bandsaw blade crosses the passage along a second, lower path. A table moves the material through the passage, whereupon the material is simultaneously cut along two planes corresponding to the upper and lower paths of the bandsaw blade. A preferred embodiment includes a first set of upper and lower wheels on one side of the passage, and a second set of upper and lower wheels on an opposing side of the passage.
