Abstract: A sharpening device for cost-effectively sharpening dulled saw blades and a method of making and using the same is provided. The sharpening device may form a tooth-like configuration adapted to rotatably grind and sharpen a saw-teeth configuration into a saw blade. The tooth-like configuration may be provided by a plurality of grinding discs and spaces alternatively stacked in a stacked configuration along an arbor that can engage a hand-held power tool. The stack configuration may be retained on the arbor through various stop mechanisms, such as a built-up section or a collar with a set screw. To prevent the stacked configuration from spinning on the arbor from torque transmission, a key way design utilizing a groove cut along the arbor and a complementary arbor hole notch may be employed. Alternatively, the arbor hole may have a shape that matches and mates with the shape of the arbor.

Abstract: In order to minimize the sliding friction occurring between the locking parts, that is, between the pawl and the rotary latch of a motor vehicle lock, it is advantageous if, during the machining process, the different latch surfaces of both locking parts are provided with a punched contour and with a contour having a oblique machining groove. Machining grooves are formed, in particular on the latch surface thereof, after stamping the pawl. Defined shapes of oblique channels and/or machining grooves are produced, for example, by milling out the machining grooves. The oblique machining grooves are produced at a defined angle and guarantee that the straight channels on the rotary latch only have a few overlapping points with the oblique grooves, if both locking parts come into contact with each other.

Abstract: A roller assembly for a rotary dresser comprise a plurality of axial segments which may be in the form of discs, each disc provided with an abrasive, radially outer surface. The discs are secured in axial alignment, each in a preconfigured rotational orientation. The disc assembly has a centrally arranged aperture for receiving a rotor shaft. The abrasive surface of the assembly can be accurately presented as an array of uniformly shaped abrasive units in a predefined pattern.

Abstract: A cutter wheel for forming scribe lines on a brittle plate has a disk with two side planes. The disk has an edge formed at the outer periphery of the disk and a shaft hole formed at the center of the disk for inserting a rotational shaft. Further, at least one groove is formed to extend from a surface of one of the side planes along the shaft hole.

Abstract: A hand-held cleaning and dressing tool for foam buffing pads includes a series of toothed cleaning wheels mounted for independent rotation on a common shaft attached to the end of a pistol grip handle. The cleaning wheels are shrouded to help capture caked material picked up from the surface of the rotating pad. The tool also includes an abrasive dressing surface to reshape the buffing pad as a result of wear. Both the cleaning and dressing tools are operated by holding the same in operative contact with the rotatably driven pad.

Abstract: Apparatus for finishing a workpiece comprising a resilient abrasive finishing element arranged for motion relative to a workpiece surface and in pressure engagement therewith. Methods of finishing a workpiece employing this apparatus are also disclosed. Both grinding and high surface quality polishing may thus be provided using the same machine tool, such as a lathe or milling machine, and appropriate finishing elements.

Abstract: A dresser for roughening the surface of an abrasive wheel has a cutter means for rotation in contact with the abrasive wheel. The cutter means includes a plurality of cutter teeth mounted on a cutter shaft. Ball bearings at each end of the cutter shaft permit the cutter means to rotate freely when held against an abrasive wheel as the wheel is rotated. A pair of hexagonal bearing supports each define a bearing receiving recess for receiving the ball bearings mounted at each end of the cutter shaft. Each of the bearing supports also defines a threaded, bolt receiving opening. A dresser body defines a cavity receiving the cutter unit and slots on opposite sides of the cavity receiving the bearing supports. The dresser body has bolt holes extending from the exterior of the body into the cavity through each of the slots. The dresser body includes a dresser handle which permits the dresser to be manipulated manually.
