An imageable belt includes a seam that is finished using an abrasive finishing machine. The seam comprises a seam width with adhesive material disposed thereon. The finishing process includes an abrasive finishing media with a finishing surface and a backer bar. The backer bar comprises a backer bar radius. The backer bar surface is positioned against the belt inner surface so that the belt outer surface contacts the finishing surface to define a finishing contact arc with respect to the backer bar radius. A tension, feed rate and pressure are applied to the finishing media. Using the finishing machine, the seam is then finished to remove the adhesive material. The finishing process results in a seam that is imageable. In one embodiment, the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE, A METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE HAVING A PLURALITY OF FINISHING HEADS, AND A METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE HAVING FIRST, SECOND, THIRD AND FOURTH FINISHING HEADS

A support for supporting a work piece to be machined is provided. The support is for use in a machine adapted to receive fluid from a fluid source. The machine includes a tool for removing material from the work piece. The support includes a body defining a chamber therein and an inlet operably associated with said body. The inlet is in communication with the chamber. The inlet is adapted for communication with the fluid source. The support also includes an outlet operably associated with the body and in communication with the chamber. The outlet is adapted to provide a stream of fluid for supporting the work piece.

Non-contact support for cylindrical machining

A roller includes a core and a ceramic coating formed over the core. The roller has a composite runout of less than 20 &mgr;m and a total indicator reading runout of less than 7 &mgr;m. The ceramic coating has a smooth finish and has controlled electric properties. This roller can be used as a donor roller for transporting toner to a photoconductive member so as to achieve high-quality image development.

Non-contact support for cyclindrical machining

A vibration inducing grinding wheel for removing material from a workpiece is provided. The vibration inducing grinding wheel is for use in a grinding machine. The vibration inducing grinding wheel includes a generally cylindrically shaped body defining a cylindrical outer periphery thereof. At least one of the composition and the contour of the outer periphery is selected so as to provide a vibration to the grinding machine such that the straightness of the workpiece is thereby improved with respect to the straightness of the workpiece ground by a standard grinding wheel having a cylindrical outer periphery thereof, the contour and composition of the outer periphery of the standard grinding wheel being uniform.

Grinding wheel with geometrical pattern

A method for producing discontinuous chips during the machining of a work piece by a cutting tool is provided. The method includes the steps of engaging the cutting tool into the workpiece to produce a continuous chip and directing a stream of cryogen toward the continuous chip, so as to rapidly cool the continuous chip and fracture the continuous chip into the discontinuous chips.

Cryogenic machining of soft/ductile materials

A development apparatus includes a housing defining a chamber holding a supply of two-component developer material including toner, and magnetizable carrier beads. The development apparatus also includes an increased reliability roller assembly within the housing for repeatably transporting a desired quantity of attracted developer material through a development zone. The roller assembly includes a first and a second preformed end cap sections each having a stub shaft portion and a cylindrical capping portion connected to the stub shaft portion and having an outer surface and assembly recesses formed into the outer surface. The roller assembly also includes a sleeve section connecting the first and the second preformed end cap sections, the sleeve section being spincast as a layer over each of the cylindrical capping portions, and into the assembly recesses of the end cap sections, so as to precisely and reliably assemble each capping portion, to the sleeve section.
