Abstract: An improved centrifugally-cast tube is provided, along with a related method and apparatus of making the tube. The tube includes a plurality of grooves and bosses that are mechanically machined into an interior surface of the tube, such as by a broaching process. The profile of grooves and bosses may be defined by a plurality of intersecting concave and convex radii. The tube is resistant to creep, carburization and metal dusting. The tube also has an enhanced heat transfer rate, and a desirable surface roughness. A method of making the tube is also provided. The method essentially consists of mechanically deforming the interior surface of the tube by passing a series of cutting inserts on support rings having incrementally-differing dimensions over the interior surface.

Abstract: In order to manufacture parts with an outer profile, a workpiece 32 is pressed by a pressure piece 24 through a ring-shaped cutting tool 34. The cutting tool 34 has a plurality of disks with inner cutting edges 62 for removing material from the workpiece 32. The cutting edges are progressively longer in the advance direction, so that each cutting edge removes material chips and the last cutting edge in the advance direction corresponds to the desired outer profile of the part. In order to improve chip removal, the chip chambers 74 located between the cutting edges communicate with the outside through radial connection openings 128 which are distributed all around their circumference. To hold the workpiece 32 securely on the pressure piece 24, a pressure pad 76 extends through the cutting tool 34 and is supported on the side of the workpiece 32 opposite to the pressure piece 32, and a hydraulic piston 80 generates a compression force on the pressure pad 76.

Abstract: An enclosed wet saw table for containing debris distributed by a wet type table saw. The enclosed wet saw table includes a table apparatus with a sink section for placing a wet saw on. There are walls on three sides of the sink for containing any splashing of liquid and debris during the cutting process. The liquid and debris drains through into a container having a pump member for filtering and re-circulating the liquid back up to the wet saw. All of the sections of the table apparatus are selectively couplable allowing the user to transport the unit and set it up on site in short order.

Abstract: In order to manufacture parts with an outer profile, a workpiece (32) is pressed by a pressure piece (24) through a ring-shaped cutting tool (34). The cutting tool (34) has a plurality of disks with inner cutting edges (62) for removing material from the workpiece (32). The cutting edges are progressively longer in the advance direction, so that each cutting edge removes material chips and the last cutting edge in the advance direction corresponds to the desired outer profile of the part. In order to improve chip removal, the chip chambers (74) located between the cutting edges communicate with the outside through radial connection openings (128) which are distributed all around their circumference. To hold the workpiece (32) securely on the pressure piece (24), a pressure pad (76) extends through the cutting tool (34) and is supported on the side of the workpiece (32) opposite to the pressure piece (32), and a hydraulic piston (80) generates a compression force on the pressure pad (76).

Abstract: A pumping station for pumping a cooling and lubricating fluid containing particulate matter such as machining chips has a compact structure with a relatively low total structural height, while still assuring that the chips are conveyed with the fluid to the pump suction inlet, without settling-out or accumulating in the apparatus. The pumping station (1) includes a collecting container (5) with at least one pump (6) arranged therein, a chip breaker (7) and a supply conduit arrangement. The supply conduit arrangement includes a supply line (2) through which the cooling and lubricating fluid containing the machining chips is received from a machining tool or transfer station. Furthermore, two branch lines (3) and (4) are interposed and connected between the supply line (2) and the collecting container (5). A first branch line (3) conveys the fluid, from which the chips have been removed, with a slight downward slope toward the collecting container (5).

Abstract: The invention is a workbench consisting of a top working surface containing a rows and columns of holes that allow dust and chips to fall and be drawn through where they land in a plenum below the surface. The top surface and the plenum are supported by a rectangular frame that includes four legs and a shelf between the plenum and the bottom of the legs. The shelf supports a doorless cabinet that includes areas for storing tools and supplies. The plenum slopes to a point containing an off center aperture which is connected through an adapter to a vacuum cleaner. The vacuum cleaner has a bifurcated input manifold with gate valves which allows the user to select between applying the vacuum to the plenum or applying the vacuum to a hose containing a vacuum cleaning tool where waste not entering the surface apertures will be removed from the top work surface.
