  • Patent number: 8122802
    Abstract: A power saw includes a saw assembly attached to a base assembly with an offset support that provides a clear path in line with the saw blade, thereby providing a miter saw, a table saw or a radial arm saw The height of the offset support is adjustable to make dado cuts, and a tilt mechanism is mounted at the top of the offset support to provide an “apparent” tilt axis near the top surface of the turntable, thereby eliminating an axle near the turntable top surface. A first fence used for miter cuts may be moved or removed during table cut operations. Alternatively, a reversible fence may be used for miter cuts when configured and affixed to the base assembly in a first position, and may be used for table or radial cuts when configured and affixed to the base assembly in a second position.

  • Publication number: 20110067541
    Abstract: This invention is a work carriage used with a cutting tool's table surface to make straight-line cuts. The device responds to the need for cutting a wide range of angles and positions on workpieces of different sizes and shapes more accurately, consistently, and safely. The invention consists of a main support which rides on a slide attached to the table surface's guide slot using a wedging action to fill the width of the guide slot. Clamps hold the workpiece to the main support along a t-shaped channel. Once set up, the main support moves precisely along the slide parallel to the guide slot and cutting plane. The main support also has threaded holes to attach workpiece stops and a fence, as needed, for making, consistent cuts. A secondary support is used to provide the necessary support with a larger workpiece that has a center of mass beyond the main support.

  • Patent number: 7406994
    Abstract: An automatic high-precision layer cutting device for separating a layer from a semiconductor substrate. The device includes a fixed positioning member for receiving at least a portion of a semiconductor substrate that has a weakened area therein and a peripheral annular notch located below the weakened area. The positioning member maintains the position of the substrate on a moveable support. A cutting mechanism having at least one blade is provided for contacting the substrate and inducing a cleaving wave therein. The cutting mechanism is operatively associated with the positioning member so that the as at least one blade contacts the annular notch, the positioning member prevents movement of the substrate and the moveable support moves away from the substrate to allow the cleaving wave to both divide the substrate at the notch into first and second parts and detach the layer from the substrate along the weakened area.

  • Publication number: 20080041208
    Abstract: A metal panel shear cutter is designed for metal panels which include support ribs. The metal panel cutter utilizes an anvil type cutting blade positioned at each side of a cutting base. Each cutting blade is pivotally connected to a cutting base in the vertical plane. The cutting base also includes supports for the ribs of the panels to allow for a smooth and clean cut of the panel. The cutting blades and a small portion of the cutting base are pivotally connected to the cutting base in the horizontal plane so they may be pivoted to the desired cutting angle while the metal panel remains fixed with respect to the base. This pivotal portion of the base includes additional supports for the ribs of the panel. These supports are adjustable to accommodate the various angles at which the panels are to be cut.
