Various examples are provided for polishing techniques for flexible tubular workpieces. In one example, a method includes supporting a tubular workpiece on a rod that extends axially through it; positioning a turning wheel against an external surface of the tubular workpiece, where it is held by magnetic attraction; and rotating the tubular workpiece by rotating the turning wheel. The external surface of the tubular workpiece is polished by the abrasive particles during rotation of the tubular workpiece. In another example, a polishing system includes a workpiece holder including a rod configured to axially support a tubular workpiece; a turning wheel with abrasive particles distributed about an outer surface; a wheel support assembly configured to position the outer surface of the turning wheel against the an external surface of the tubular workpiece, where it is held by magnetic attraction. The external surface is polished during rotation of the tubular workpiece.

An integrated equipment for processing a plurality of fiber optic ferrules comprises a polishing system, a ferrule cleaning system, a drying system, a wiping system, and a robot system. The polishing system polishes a plurality of front end faces of the plurality of fiber optic ferrules mounted on a carrier. The ferrule cleaning system cleans the carrier and the fiber optic ferrules on the carrier after the fiber optic ferrules have been polished. The drying system dries the carrier and the fiber optic ferrules on the carrier after the carrier and the fiber optic ferrules have been cleaned. The wiping system wipes the front end faces of the fiber optic ferrules on the carrier after the carrier and the fiber optic ferrules have been dried. The robot system transfers the carrier to the polishing system, the ferrule cleaning system, the drying system, and the wiping system.

A downhole tool or component, such as a hydraulic fracturing ball, may have a base body having an outer surface. The outer surface of the base body may have a lapped coating thereon. The downhole tool or component may be made by lapping the outer surface of the base body with a lapping slurry. The downhole tool or component may be used in downhole applications, such as hydraulic fracturing, and may resist degradation upon exposure to fluids, such as production fluids.

The precision lapping and polishing device for external cylindrical surface of disk part and its taper error adjustment method. The device composes a circular baseplate, slant rails, baffles, pressure plates, copper blocks, a washer blanket; blanket plates, a set of bead shafting, a friction driving wheel, a DC motor, a mobile power supply, a LED lamp and a cover body. By adopting the working principle that the generatrix rotates around the fixed axis to form the cylindrical surface, the ultra-precision machining of the cylindrical surface of disk part is realized. The radial-continuous-automatic-micro feeding of the disk part is realized by thinning the thickness of the circular baseplate which is internally tangent to the generatrix of the circular baseplate during the process of lapping and polishing. The device has the advantages of operating simply, adjusting conveniently, low cost and is of important value for popularization and application.
