Abstract: A tool for removing material from a surface includes a body defining a longitudinal bore and an opening connecting an outer surface of the body to the longitudinal bore. A cutting element comprising a cutting surface is dimensioned to be at least partially received by the opening. The cutting surface is configured to translate from a first position to a second position in response to a centrifugal force. In the second position the cutting surface is extended outwardly through the opening, beyond the outer surface of the body. In one example, the tool may be used to remove material, such as oxidation, from the inner walls of a cylindrical article selected from a pipe and a tube.

Abstract: A radially inwardly open raceway formed in a nut centered on a nut axis is machined by of oscillating the nut about the nut axis while pressing a tool secured in a holder radially outwardly into the raceway of the nut. The holder is moved parallel to the nut axis and oscillated about a tool axis perpendicular to the nut axis synchronously with the oscillation of the nut about the nut axis. Springs brace the tool against the holder parallel to the nut axis such that the tool can move limitedly in the holder against spring bias parallel to the tool axis.

Abstract: A honing tool comprises a tubular tool body fastened with an end section in a tool shank and a cutting region on an opposite end section with at least one honing-stick accommodating opening. The dimensions of the honing-stick accommodating opening and of the honing stick are matched to one another so that the honing stick is accommodated in a radially movable manner, and essentially free of play in a circumferential direction of the tool body, between boundary surfaces of the honing-stick accommodating opening. A play-compensating device between the honing stick and the honing-stick accommodating opening comprises at least one elastically deformable supporting element which is supported with a pressure force, in a fitted state of the honing stick, on one hand on a side surface of the honing stick and on the other hand on a boundary surface, opposite the side surface, of the honing-stick accommodating opening.

Abstract: A honing tool holder that provides a capability for automatically feeding the honing elements or stones when in the bore of a work piece, and for automatically stopping the feeding when a particular condition such as a bore size, is reached, so as to enable use of an in-process adjustable feed honing tool in a machine tool, machining center, or the like, lacking a feed mechanism or system. The holder can also include apparatus to automatically prevent feed past a limit. Both the feed force and feed limit can be adjustable, including by simple movements of the tool holder by the machine tool.

Abstract: The application describes a honing tool for use with a CNC machine. A fluid actuator provides the mechanism for causing radial adjustment of abrasive elements. The actuator consists of a piston and cylinder assembly mounted within the tool and powered by cooling fluid of the CNC machine. Actuation motion is driven by a helical drive on the piston which imparts rotary motion to a feed rod. Upper and lower feed rod sections are connected through a clutch. Axial movement is imparted to a feed cone by threaded engagement between the feed cone and the lower feed rod section.

Abstract: A lapping tool capable of increasing the accuracy of a lapping operation, extending the life of lapping tool itself, adjusting a lapping diameter, and coping with the lapping operation of various diameters, comprising a lapping tool body having a lapping part on the outer peripheral surface thereof and slits provided in the lapping tool body axially between the tip part and the base part thereof.

Abstract: The invention relates to a knife sharpening machine comprising a plate-type holding device on which two intersecting sharpening bars are rotationally mounted and loaded in relation to each other by means of springs. The sharpening bars, at least in the grinding area, are made of a ceramic material. The plate is provided with a slit which is open on one end and closed on the other, extending as far as the intersection point of the sharpening bars. When pressure is exerted by the knife in the direction of the closed slit end, the sharpening bars are spread apart from each other counter to the force of the springs. Curved guides are provided on both sides of the slit. The ends of the sharpening bars, facing away from the axes of rotation thereof, are guided therein.

Abstract: A resilient sanding mechanism is provided for sanding the contours of a working surface, such as an aircraft body. The mechanism comprises an elongate frame having a frame axis, a sander mechanism pivotally engaged to the frame and having a sanding surface disposed distal to the frame. A resilient biasing apparatus is engageable to the sander mechanism and to the frame, for biasing the sander mechanism sanding surface in a predetermined orientation with respect to the frame axis.

Abstract: The pipe cleaner attachment includes a housing, a shuttle, and a shuttle guide. The housing has a closed end, an open end, a key and two brush levers and brush pad guide slots. The shuttle guide is a rod clamped in a bore through the closed end of the housing. The end of the rod outside the housing is clamped in a drill chuck for use. The shuttle is slideably mounted in the housing on the shuttle guide and engages the housing key, A pair of brush levers are pivotally mounted in the brush guide slots. A brush pad is attached to an end of each brush lever. Burnishing grooves are provided in the shuttle for burnishing the open ends of pipes with two different diameters. Upon insertion of a pipe into the housing, the pipe end is reamed, the burnishing grooves burnish the pipe end, the shuttle is moved toward the closed end and the brush pads clean the outside surfaces of the pipe.

Abstract: A rotating tool includes e hub having a central section for attaching the hub to a rotatable shaft and a disc-shaped hub section surrounding the central section. The central section and the hub section are comprised of an elastomeric material and formed as a unitary body. A plurality of sleeves are embedded in the hub section with each sleeve having an end terminating in the hub section and an opposing end protruding from the hub section. The protruding ends are spaced around the circumference of the hub section. Working tips are fastened in the protruding end of each sleeve. Each working tip has a base disposed in the protruding end of the sleeve and a tip protruding from that end of the sleeve. In an alternative embodiments, the hub section has a plurality of projections in which the sleeves are embedded.
