Abstract:
The invention relates to a method for metal-cutting machining a workpiece during which a sufficient lubrication of the machining tool (150) and a sufficient cooling of the machining tool (150) and of the workpiece (102) being machined are ensured while simultaneously preventing chips produced during machining from remaining inside recesses of the workpiece. The inventive method comprises the following steps: introducing a lubricant provided in a free-flowing state into at least one recess (118, 120) of the workpiece (102); solidifying the lubricant (148) inside the recess; metal-cutting machining the workpiece during which at least one machining tool comes into direct contact with the lubricant and is lubricated by said lubricant; transforming the lubricant remaining inside the recess of the workpiece into a free-flow state, and; removing the lubricant from the workpiece.
Abstract:
A facing tool (10) includes a fixture (12) that securely holds a workpiece (w), and a fixture retainer (82) that secures the fixture (12) and workpiece (w) against axial and radial movement during a facing operation. In one embodiment, the fixture (12) includes a two piece construction that allows a first piece (68) to be swung away from the second piece (62) to accommodate a variety of sizes of workpieces. Provision is also made for a positive load on the cutting tool to reduce or eliminate tool vibration, as well as a chip shield (130) that deflects debris away from the workpiece. A tool spindle (18) is provided that allows for a plurality of cutting tool positions on the spindle to accommodate different workpiece diameters.
Abstract:
An attachment for use with a vacuum powered debris removal system, said attachment comprising a debris collection bowl, said bowl having a first aperture through which a material cutting tool may be removably inserted, a second aperture through which a vacuum source may be connected, and a third aperture the open circumferential face of which is designed to lie substantially in contact with a material undergoing a cutting operation, such that in use, as debris is generated by the action of the cutting tool on said material, substantially all debris is collected in said bowl and thereby extracted through the second aperture by the action of the vacuum source.
Abstract:
Apparatus capable of performing wet and dry machining processes such as a hobbing machine for producing spur and helical gears, shafts, splines, and the like, by wet and dry hobbing methods. The apparatus comprises means to remove metal chips resulting from the wet and dry machining processes from the apparatus via respective independent wet and dry chip outlets (72, 70). The chip removal means comprises a transfer means (74) located in the machine base (2) with the transfer means (74) being reversible in direction in order to convey metal chips, emanating from the machining process, to the respective wet or dry chip outlet (72, 70). The chip removal means (74) enables metal chips from wet machining processes to be conveyed to and discharged from an outlet (72) in one side surface (10) and metal chips from dry machining processes to be conveyed to and discharged from an outlet (70) in another side surface (8).
Abstract:
A valve (10) for installation on a flow line (190) while the flow line (190) is under pressure. The valve (10) includes a two-part valve body (12, 14) and a valve cartridge (50). Each body portion (12, 14) has a semi-cylindrical channel (24, 36) sized to mate with the flow line (190). The body portions (12, 14) are secured together with a portion of the flow line (190) enclosed and sealed in the channels (24, 36) of the body portions (12, 14). A throughbore (26, 38) extends through the two body portions (12, 14) and fully intersects the channels (24, 36) of the two body portions (12, 14). One end of the throughbore (26, 38) is adapted for attachment of a cutting tool (160), which is used to cut out the portion of the flow line (190) disposed in the throughbore (26, 38). After the flow line (190) is cut, the valve cartridge (50) is directed into operating position. A valve stem nut (66), a valve cap (56), a valve plug (86), gaskets (44), seals (70, 88) and connectors (40) are provided to close and seal both ends of the throughbore (26, 38).
Abstract:
Safety debris collectors (26) for collecting dust and debris, such as concrete particles and dust, rock chips, steel particles, radioactive particles, insulation and other particles and dust when drilling, chipping and using stud guns, drills, piston drive devices and other operating tools used in the construction industry which create working dust or debris and the like. The safety debris catcher (10) does not rotate or move with the operating portion of the tool (50), it is easily and readily connected to and detached from an operating tool (50) or device, it can be used in confined spaces, such as spaces between beams, braces, and ceilings at different elevations, and it can be used at any angle and effectively collect debris, dust and other particles. A rotating inner disk (60) within the base of the debris catcher forms a rotating inner surface of a chips chamber (40), urging debris away from the tool into a debris receiving chamber.
Abstract:
Described is a method of producing deep bores, in particular in wood. In this method, misdirection of the drill is prevented and adequate chip removal is ensured. Intended for use in this method is a deep-bore drill comprising two hollow shafts (21, 22) fitted with cutter elements, the hollow shafts being fitted concentrically one inside the other and being rotatable independently of each other. Incorporated in this deep-boring drill are channels (24, 25) for the supply and return of compressed air which not only cools the drill but also removes the chips from the drill hole.
Abstract:
A hole saw drill guide is described. The drill guide can be used when drilling holes in pipe or tubes. The hole saw drill guide includes a guide tube base assembly and an arbor shaft assembly. The guide tube base assembly is chained or otherwise secured to a pipe. The arbor shaft assembly is removably engaged with the guide tube base assembly and during use of the device, rotates within a guide tube of the base.
Abstract:
The wear status of a micro-endmill tool may be inferred by monitoring the chip production rate of the tool in operation. Chips may be extracted from a work area, captured on an adhesive surface, imaged, and counted to determine the chip production rate. When the rate of chip production falls, the feed rate of the micro-endmill may be increased to a level suitable for the current state of tool wear. In this manner, costly and inconvenient work stoppages to evaluate the wear status of a tool are eliminated.
