Blocks of rigid insulation material, such as cellular glass blocks, are fed into the automated machine. The blocks are first placed on an automatic programmed moving conveyor belt and are first cut on a pre-determined angle developed from the horizontal and vertical centerline of the block. This cut is made by an angled, vertical band saw mounted with its blade in the center of the moving conveyor, thus producing one angled side on each of the two cut blocks. The remaining three primary sides of the cut blocks are machined to create curved sectional blocks that are used to cover the outer surface of large bore pipe systems or other cylindrical items such as tanks.

  • Patent number: 6865787
    Abstract: A numerical control (NC) processor with an onboard grinding unit is disclosed in which a workpiece is first cut in a preselected contour with a Y-axis cutting tool, and then subjected to honing operation intact whereby both the cutting and honing operations can be performed with just a single processor with high-speed, high-acceleration. With the NC processor, the Y-axis cutting tool is mounted on a sliding base above an X-axis table in a way allowed to move back and forth in a Y-axis direction, while a grinding unit is installed in close proximity to the sliding base. A slider moves back and forth in synchronized relation with rotation of a work spindle to first let the Y-axis cutting tool cut the workpiece into a preselected contour, and then cause a buffing material of the grinding unit to grind a work surface of the workpiece into a high-quality surface finish in conformity with a programmed contour while the workpiece remains held intact in a chucking device.

  • Patent number: 6746307
    Abstract: The invention relates to a method for re-profiling the running surface of a rail, preferably the convex portion of the rail head cross-profile of a rail, especially a railway rail, by peripheral milling. The aim of the invention is to obtain a profile that meets the requirements and has few corrugations. To this end, for producing the profile in a single peripheral grinding step, more than five, preferably nine milling tracks are produced that are oriented in parallel to the longitudinal direction of the rail. Optionally, the running surface, preferably the convex portion of the rail head cross-profile including the running surface is ground afterwards.

  • Patent number: 6632125
    Abstract: A method of manufacturing aluminum frames for photomask protective films comprises the step of: providing a square-shaped hollow or solid strut aluminum material, fastening the bottom end of the aluminum material to a base of a machine tool, using a milling cutter to fabricate and form a hollow trough for a selected depth in the aluminum material from the top surface thereof, and using a cutting tool to cut off the aluminum material at the periphery of the hollow trough to form individual aluminum frames for the photomask protective films. The method of the invention uses fewer chucks and screw bolts during machining, and can reduce chuck setup time and simplify machining processes.

  • Patent number: 6609997
    Abstract: A rotary die cuter for a box making machine has an abrading cylinder mounted for rotation alongside the anvil for engaging and resurfacing the blanket of the anvil on a virtually continuous basis to smooth, level and even the surface of the blanket. This resurfacing occurs during normal operation of the rotary die cutter so no production is lost. The abrading cylinder has a sheet layer of abrasive material spirally wrapped on the surface of the cylinder and bonded thereto with adhesive material on the backside of the sheet layer. The abrading cylinder is movable towards or away from the anvil by a servo motor and gearbox. The position of the abrading cylinder relative to the anvil is determined by an encoder which sends the information to a computer or programmable controller which calculates the changing diameter of the blanket and the amount of speed change that must be imparted to the anvil to compensate for its changing diameter.

  • Publication number: 20030104768
    Abstract: A web-format polishing pad for mechanical and/or chemical-mechanical planarization of microelectronic substrate assemblies, and methods for making and using such a web-format pad. In one aspect of the invention, a web-format polishing pad for planarizing a microelectronic substrate is made by slicing a cylindrical body of pad material along a cutting line that is at least substantially parallel to a longitudinal centerline of the body and at a radial depth inward from an exterior surface of the body. For example, a web of pad material can be sliced from the body by rotating the cylindrical body about the longitudinal centerline and pressing a cutting element against the rotating cylindrical body along the cutting line. The cutting element can be a knife with a sharp edge positioned at the cutting line and a face extending along a tangent of the cylindrical body.

  • Publication number: 20030064666
    Abstract: In one embodiment, the invention is directed toward inline lapping of magnetic tape. The lapping process is performed inline with one or more other magnetic tape manufacturing processes. In this manner, the number of times the magnetic tape is un-spooled and then re-spooled can be reduced. Consequently, the amount of handling of the individual tape pancakes can also be reduced, thus avoiding damage to the edge of the tape, or other damage associated with tape pancake handling.
