摘要： A process including providing a hollow cvlindrical substrate, the substrate having a dry outer surface describing a curvilinear plane, a dry inner surface describing a curvilinear plane, a first end opposite a second end, and an imaginary axis extending from the first end to the second end, supporting the substrate, machining at least a portion of at least one end of the substrate with at least one dry polycrystalline diamond cutting tool in the absence of liquids to remove material from the substrate, and simultaneously maintaining, during machining, the dry inner surface of the cylindrical substrate free of the material machined from the at least one end of the substrate by the at least one dry polycrystalline diamond cutting tool.

摘要： A mounting apparatus for mounting a hollow work-piece on a machine includes a circumferential groove formed into an outer surface of a cylindrical supporting fixture of the machine, a dampening plug assembly for positioning inside the hollow workpiece adjacent the cylindrical supporting fixture, and an end pressure reducing device for mounting within the circumferential groove for centrifugally supporting and enabling the reduction of machining-induced pressure from the end of the hollow workpiece.

摘要： A photoreceptor aluminum alloy substrate is prepared with specific roughness characteristics and an oxide layer for use in multi-layered electrophotographic photoreceptor. A photoreceptor substrate, or drum, is placed in a lathe and turned using a polycrystalline tool to achieve specific roughness characteristics. A oxide layer is then allowed to form on the roughened photoreceptor substrate. The roughened surface of the photoreceptor aluminum alloy substrate in conjunction with the oxide layer on the roughed surface reduces variances in surface energy across the photoreceptor substrate, and eliminates, or greatly reduces, a number of Tiger Stripe and Tiger Tail defects that may occur in an undercoat layer subsequently applied to the roughened photoreceptor substrate. The approach eliminates the need for wet honing and thereby significantly reduces the complexity and cost of fabricating a multi-layered electrophotographic photoreceptor.
