Means To Remove Flash Or Burr Patents (Class 409/258)
  • Patent number: 8234771
    Abstract: The invention provides an enhanced method and system for machining an array of components. A holding mechanism is provided for holding an array of components in a machining process. The holding mechanism comprises: a rigid base plate and at least one support for holding a raw material while machining, one end of each support being coupled to the rigid base plate. The holding mechanism is further provided with a secure plate movably coupled to the rigid base plate. The secure plate is provided with one or more holding parts such as double-sided tape or guiding pins for holding the raw material. The secure plate can be elevated to hold the raw material during a machining operation such as peripheral machining.

  • Patent number: 6276881
    Abstract: Apparatuses and methods are implemented for machining a longitudinally extending slot in a bore of a component. The component is gripped in a gripping device of a workholding device. A cutting operation is performed in order to cut the slot in the bore by a cutting tool. The cutting operation forms burred slot edges. The edges are further machined by inserting a deburring device into the bore. Relative angular reciprocation for a limited angle is imparted between the deburring device and the component.

  • Patent number: 6195859
    Abstract: In the present invention, in cutting the top and bottom surfaces of a hot-rolled sheet by the rotation of milling cutters holding the sheet therebetween in the thickness direction of the sheet in the running process of the hot-rolled sheet, the cutting resistance determined by the cutting conditions including the type of hot-rolled sheet, the temperature in cutting, and the cut depth is controlled by the adjustment of cut depth, and cutting is performed by making the tension produced on the hot-rolled sheet by the cutting resistance lower than the breaking strength of the joint portion to prevent the breakage of hot-rolled sheet.

  • Patent number: 4793749
    Abstract: In a process for edging metal strips, especially nonferrous metal strips, by means of an edging machine wherein the longitudinally driven metal strip is guided between an upper and a lower linear guide and cutting tools are disposed successively along the line of movement of the strip, on either side of the linear guides. It is proposed according to the invention that a liquid or gaseous fluid be forced out of the central part of the linear guides at individual points along the line of movement, into the clearance between the metal strip and the linear guides. In a linear guide for carrying out this process, provision is made according to the invention such that, in each linear guide face confronting the metal strip, there are a series of grooves running longitudinally along the center of the guide, the grooves being separate from one another and connected to inlets for the fluid.

  • Patent number: 4701085
    Abstract: Method and apparatus for broaching an outer surface of a resin layer of a resin-coated part whose external side surface is coated with the resin layer, wherein a backing plate is used to back the resin-coated part such that the plate is held in contact with an end face of the part at which a movable broach terminates a broaching cut in a direction along the outer surface of the resin layer. The backing plate has an external profile similar to a cutting edge contour of the broach. The backing plate is positioned on a work bed of the broaching apparatus such that its external profile is inwardly spaced from the cutting edge contour of the broach a plane perpendicular to the direction of movement of the broach. The backing plate, which forms a part of a work-holding fixture, serves to protect the resin layer from breakage, chipping or other defects at the end of a broaching pass along the outside of the resin-coated part.

  • Patent number: 4376603
    Abstract: Apparatus for removing shop or screw machine part or workpiece. More specifically, the apparatus comprises a bushing with a hole therein for axially guiding the burred end of the part into engagement with a disintegrating mechanism such as a saw, grinder or abrader, in combination with a stop for arresting both the inward movement of the part and the resulting disintegration when the burr becomes disintegrated flush with said flat end.
