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 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.

A sample cutting assembly includes a base block, a saw pressure plate, an external blade guide, and an internal blade guide. The cutter can be used to conveniently remove samples for Material testing to determine serviceability or material condition. Apparatuses and techniques for using the sample cutting assembly are also disclosed.

A food-cutting apparatus has a base; a trolley for placing a food object; a cutting device having two saw wheels, a power source, and a saw belt that is wound around the two saw wheels as a loop. The power source drives the two saw wheels to rotate and further drives the saw belt to circle. The trolley moves the food object so that the food object is cut by the saw belt. The saw belt has teeth oppositely at its two edges. The detector monitors intactness of the teeth and generates a warning signal when determining that any of the teeth is worn. The controlling device cuts off the power source and slows down the trolley when receiving the warning signal.

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.

A hand-held band saw includes a band saw body and an supporting device. The supporting device includes a fixing member, a slider, a supporting member, and a connection assembly. The fixing member is fixedly connected to the band saw body, the slider is slidably connected to the fixing member, the supporting member supports a workpiece and is connected to the slider, and the connection assembly connectes the slider and the supporting member. When the slider moves, the connection assembly is capable of enabling the supporting member to move along with the slider. The connection assembly comprises a buffer member mounted between the slider and the supporting member.

A ribbon saw with a double security system is provided that includes a cutting ribbon (3), vertically installed between an upper part (1a) and a lower part (1b) with driving mechanism and control electronics. The control electronics include a first artificial vision security system, with a camera (5) and a second magnetic artificial vision security system, with an inductive sensor or metal detector (6) installed on the table (4), in front of the cutting ribbon (3). The security system is connected to one or two braking systems (14,15) based on a disc (14) and a pneumatic clamp (15) that stops the mechanism of pulleys (12a, 12b) of the ribbon (3), when it detects the color and the metallic or ferrous material of the gloves that the operator wears.

The saw being connected to a cloud based system that enables a safer ecosystem and cross statistic sharing of safety parameters.

A handheld band saw includes a housing, a handle supported by the housing and configured to be grasped by a user during a cutting operation, and a motor supported by the housing. The band saw further includes a drive wheel assembly that is at least partially disposed within the housing and a saw blade driven by the drive wheel assembly. The band saw further includes a drive assembly positioned between the motor and the drive wheel assembly. The drive assembly is configured to transfer torque from the motor to the drive wheel assembly, causing the drive wheel assembly and the saw blade to rotate. The drive wheel assembly includes a wheel having a recess in which a portion of the drive assembly is received to shorten an overall length of the motor, drive assembly, and drive wheel assembly.

The present disclosure is directed to a bandsaw. The bandsaw may be cordless bandsaw utilizing a battery pack to provide power to an electric motor. The electric motor may drive an transmission. The transmission may be mechanically coupled to a drive wheel. The drive wheel, in conjunction with a driven wheel turn a blade for a cutting operation. The bandsaw may include a base for housing the drive and driven wheels. The base may also include an integrated transmission housing for housing the transmission.
