  • Patent number: 6280087
    Abstract: A guide for a high speed steel rolling mill comprises two rolling members, between which the work product passes mounted for rotation on a base member. Each roller has a frusto-conically shaped bearing recess formed therein and each guide roller is mounted on a mating, frusto-conically shaped projection which protrudes from the base member. Each of the projections has a central oil duct which serves to feed a lubricating oil under pressure into the frusto-conically shaped space between the roller and its mating projection. The lubricating oil serves to form a film between the stationary projection and the rotating guide roller. Because of the conically shaped mating surface, the lubricating oil tends to “lift” the guide roller from the surface of the supporting base. Each rolling member is provided with a vane structure to permit the rolling member to be prespun by the impingement of a cooling fluid on the vane surface thereof.

  • Patent number: 6205895
    Abstract: A tube cutter designed for cutting a pipe where access is limited to the interior of the tube only. A rotatable cutter head mounted at the end of an elongated drive shaft carries a plurality of cuffing wheels. The tube cutter is inserted into a tube to be cut from one end thereof using the elongated drive shaft to position the cutter head in the tube. When the cutter head is inserted into the predetermined location, a feed drive is energized which rotates a scroll head to cause the cutting wheels to move in a radial direction to advance and engage the interior surface of the tube in a concentric manner undergoing cutting. When the tube has been severed, the feed drive rotation is reversed to retract the cutting wheels into the rotatable head, so as to enable removal of the rotary tube cutter from the tube.
