  • Tool bit with multiple cutting tips
    Patent number: 7739931
    Abstract: A tool bit suited to use in a machining apparatus for lathing of photoreceptor blanks includes a cutting portion which defines a plurality of projections. During lathing, the projections extend into the blank successively greater distances. When the blank is rotated, each projection cuts a successively radially inward portion of the workpiece. The resulting swarf is thinner and generally easier to handle than for a tool with a single cutting edge, thereby enabling vacuum suction of the swarf.
    Type: Grant
    Filed: July 30, 2007
    Date of Patent: June 22, 2010
    Assignee: Xerox Corporation
    Inventors: Ronny W. F. van Asten, Theo G. M. J. Gommans, Tinus Zuetenhorst

  • Cutting fluid
    Patent number: 5534172
    Abstract: An aqueous-based cutting fluid for machining photoreceptor substrates contains:(A) at least one antioxidant;(B) one or more surfactants, at least one of which is a polysiloxane surfactant;(C) at least one lubricant; and(D) water.The cutting fluid can also optionally contain one or more biocides. The cutting fluid is environmentally safe, non-toxic and biodegradable and can be removed in a postmachining cleaning process using only high quality distilled water.
