摘要： The present disclosure provides for a saw for cutting a hard material. The saw includes a housing, a motor mounted to the housing and an arbor mounted in a fixed position relative to the housing. The arbor can further include a saw blade, where the motor turns the arbor to rotate the saw blade. A shield mounted to the housing covers the saw blade, where the shield includes an elongate mark that aligns with the circumferential cutting edge of the saw blade. The housing further includes a cut-depth guide that includes a depth post that passes through a sleeve having a latch that can releasably engages the depth post to fix the position of the depth post relative to the sleeve. A guide wheel extends from the depth post, where the guide wheel contacts the hard surface to maintain a cut depth of the saw blade.

摘要： There is provided a cutting apparatus with which, even if a plate body to be cut is warped, it is easy to obtain a cut product of the same quality as when a plate body which is not warped is cut. The cutting apparatus is provided on a conveyor for conveying a plate body and cuts the plate body being conveyed by the conveyor. The cutting apparatus includes a cutting blade that cuts the plate body in a direction parallel to a direction of conveying the plate body, and a pressing unit including, at a side position of the cutting blade, a pressing plate provided to be movable between a pressing position where the pressing plate presses the plate body and a retracted position where the pressing plate is retracted from the pressing position. The cutting apparatus cuts the plate body with the cutting blade while pressing the plate body with the pressing plate.

摘要： A cart for carrying a saw having a saw blade, a motor drivably coupled to the saw blade, a saw control unit to selectively activate the motor in response to a first input control signal from a trigger, and a first connector in communication with the saw control unit. The cart includes a remote actuation system having a cart control unit, a throttle configured to provide an input to the cart control unit, and a second connector configured to connect with the first connector of the saw. The cart also includes a wire interconnecting the cart control unit and the first connector. The wire configured to transmit a second input control signal from the cart control unit to the saw control unit upon receiving the input from the throttle, via the first and second connectors, to selectively activate and vary a rotational speed of the motor and the saw blade.

摘要： The present invention relates to an automatic sawing machine for cutting blocks of natural and/or concrete stone material, which comprises a single motorized conveyor belt having a conveyor plane for transporting the material to be cut and a driving wall placed substantially at 90° with respect to said conveyor plane so that all together contribute to give the conveyor belt a substantially “L”-shape. The machine comprises a support fixed to the machine and a rotatable crown element placed at the top of said support, provided of a plurality of protuberances spaced apart from each other so as to allow each of said protuberances to be inserted in turn into one of said slot obtained in one of said second portions of said strips, following the movement of the conveyor belt. Methods of cutting blocks of natural and/or concrete stone material with the automatic sawing machine are also provided.

摘要： A head for a bridge processing machine includes a support having a frame loosely connected to a bridge and a shaft extending along a rotation axis and rotatable relative to the frame around the axis, a tool holder assembly supporting a tool to allow processing of an object by the tool and including first constraint means to integrally constrain the tool holder assembly and the shaft, gripping means including a base portion, a gripping device movable relative to the base portion, to define an operating position wherein it engages an object, and an inoperative position, and second constraint means to constrain idly the base portion and the shaft, wherein the gripping means and the tool holder assembly include interface means for blocking reciprocal rotation between the tool holder assembly and the base portion so that the tool holder assembly may drag the gripping means when rotated around the rotation axis.

摘要： A tile saw includes a saw unit having a motor and a saw blade driven by the motor, a table through which the saw blade at least partially protrudes, and a pan positioned underneath the table and including a channel configured to receive at least a portion of the saw blade. The channel extends along a longitudinal axis perpendicular to a rotational axis of the saw blade such that fluid moves through the channel in a first direction in response to rotation of the saw blade. An interior wall is positioned adjacent the channel. The interior wall is obliquely oriented relative to the longitudinal axis of the channel to redirect the fluid in a second direction that is different from the first direction.
