  • Method and apparatus for machining a casting surface
    Patent number: 4964766
    Abstract: A fixturing apparatus for locating, orienting and holding a workpiece during a milling operation, having a workpiece specific mounting provided with means for accurately and reproducibly positioning the workpiece within the fixture. The workpiece specific mounting has a workpiece specific pattern of clamping, vibration dampening and supporting devices to hold the workpiece during the milling operation. Accurate, reproducible location and orientation of successive workpieces of the same geometry on the apparatus for the same milling operations is achieved quickly and positively and vibration and workpiece distortion are minimized during the milling operations.

  • Spindle driver for machine tools
    Patent number: 4934040
    Abstract: A spindle driver for a machine tool is disclosed which is adapted to move the spindle and a tool driven thereby in a helical path with variable pitch and with an orbital radius which may be varied. A quill is mounted on a support member and driven by a variable pitch drive mechanism in the form of a differential lead screw to provide a selectable ratio of axial motion to rotative motion of the quill. A spindle carrier is rotatably mounted on the quill for rotation about an eccentric axis offset from the quill axis. A spindle motor and a spindle driven thereby is mounted on a carrier with the spindle axis offset from the eccentric rotation axis. The orbital radius for the spindle is adjustable by rotation of the spindle carrier about the eccentric rotation axis to adjust the offset of the spindle axis.
