| 20080200101 | POLISHER SHUTTLE, AND A METHOD AND A POLISHER DEVICE MAKING USE THEREOF - The polisher shuttle serves to polish the inside walls of cylindrical tubes, in particular tubes for medical use. It comprises radial projections that are flexible along the axial direction, suitable for polishing the inside walls of tubes merely by relative movement between the shuttle and the tube, the shuttle passing inside the tube. In a longitudinal section, the sections of the projections form a series of separate undulations that are long and thin in the radial direction. The polishing method made possible by the shuttle is particularly simple, since a single pass of the shuttle can suffice for performing polishing; the method is thus fast and easy to automate, e.g. in a polisher device of the invention. | 08-21-2008 |
| 20090209178 | One step copper pipe fitting abrasion preparation - A method for abrading or polishing and reaming the terminal ends of tubing or fittings using a hand-held electrically powered device having a rotating member capable of accepting a standard shaft which has attached to it a male and female abrasive member which will polish or abrade the inside and outside of a length tubing or fitting respectively uses the same tool. Also attached to the standard shaft is a reamer for removing unwanted material from the end of the length of tubing. All of these members are attached at the same end of the standard shaft, thereby allowing all the operations to be performed at one time on each tubing or mating fitting member. In addition, the standard shaft may be connected to a clutch release mechanism allowing the tool mechanism to disengage upon the application of excessive torque. | 08-20-2009 |
| 20100081365 | Grinding Surfaces of Workpieces - A method of grinding a workpiece with a grinding wheel is provided wherein the shape of the wheel is distorted in a predetermined manner during grinding by changing the speed of rotation of the wheel.

The systems, tools, and methods may also be applicable for transforming regions of pipe, coated or uncoated, and which are otherwise unsuitable for sealingly engaging press fittings, so that reliable and leak-proof seals can be made between the pipe and press fittings. | 02-24-2011 |
| 20120088440 | FINISHING OF SURFACES OF TUBES - The present disclosure involves various embodiments for finishing the internal wall of a capillary tube. A quantity of abrasive particles and a rod are placed in a capillary tube, wherein a portion of the abrasive particles is magnetic. A magnet is positioned near a side of the capillary tube, thereby attracting the abrasive particles toward an internal wall of the capillary tube. A relative rotation of the capillary tube is produced with respect to the magnet, thereby causing the abrasive particles to finish the internal wall of the capillary tube. | 04-12-2012 |
| 20120202404 | BORE MACHINING METHOD AND APPARATUS - A method of machining the internal bore of a hollow pipe comprises honing material from inner surface of the bore the pipe. A honing apparatus for use in the method comprises a machining tool comprising a honing head adapted for insertion into the end of a pipe to remove material from the inner surface of the pipe by abrasion. | 08-09-2012 |
| 20130029565 | Center Lap Tool Machine for Large Transmission Gears - A machine system and method for simultaneously lapping a first machining surface of a hollow shaft and an opposing second machining surface of the hollow shaft, the machine system having a brake subsystem for securing the hollow shaft in a relatively stationary position while a drive subsystem rotates a lapping tool within the hollow shaft such that the lapping tool laps the first machining surface with an abrasive surface of a top lap while simultaneously lapping the second machining surface with an abrasive surface of a bottom lap. | 01-31-2013 |
| 20130059502 | Abrasive Cutting Tool and Cutting Method - A tool for removing material from a surface includes a body defining a longitudinal bore and an opening connecting an outer surface of the body to the longitudinal bore. A cutting element comprising a cutting surface is dimensioned to be at least partially received by the opening. The cutting surface is configured to translate from a first position to a second position in response to a centrifugal force. In the second position the cutting surface is extended outwardly through the opening, beyond the outer surface of the body. In one example, the tool may be used to remove material, such as oxidation, from the inner walls of a cylindrical article selected from a pipe and a tube. | 03-07-2013 |
| 20140220868 | System for Dressing A Centrifugal Clutch - A system for dressing centrifugal clutches has a drum tool with an internal abrasive surface, and a flap tool with abrasive flaps. The drum tool can replace the clutch drum on the clutch driven shaft to dress the clutch shoes, or the flap tool can replace the clutch shoes and mechanism on the clutch drive shaft, which may be the engine crankshaft, to dress the clutch drum. In either case, the tool being used and the component being dressed can accurately simulate the engagement of the clutch shoes and clutch drum in operation, so that the clutch drum and shoes can be accurately dressed to the correct shape, matching each other, for use. | 08-07-2014 |
| 20140364042 | Cylindrical Surface Profile Cutting Tool and Process - A method of cutting a profile in a cylinder surface.
