    摘要: A pivoting wafer carrier having a minimum of internal friction and a smooth, continuous pivoting motion. The pivot mechanism includes a lower ring mounted on a pressure plate, an upper ring mounted on a housing upper plate and ball transfer units disposed on the lower ring. Corresponding bearing wedges depend downwardly from the upper ring. As the pressure plate tilts during the polishing process, the load balls of the ball transfer units roll against the corresponding wedges, thus producing a smooth, continuous pivoting motion. A universal joint may be provided to the carrier to effect the rotation of the carrier and to aid the smooth, continuous pivoting motion of the wafer carrier.

    摘要: The present embodiments provide methods, systems and apparatuses for use in grinding work pieces, such as wafers. Some embodiments provide methods that position a grind spindle to contact a first grinding spindle to a face of a work piece, remove a portion of the face, and control the removing of the portion of the face according to a control algorithm. This control algorithm can comprise determining a force applied to the work piece during the removing of the portion of the face, adjusting a feed rate of the first grind spindle when the force applied to the work piece has a predefined relationship with a first threshold level; and dressing a portion of the first grinding portion when the force applied to the work piece has a predefined relationship with a second threshold level that is greater than the first threshold.

    摘要: Programmable electric and hydraulic machine for shaping laps such as are used to form or polish opthalmic lenses, comprises vertically oscillatable, longitudinally displaceable arm carrying a point cutter which is functionally engageable by radially extensible, rotating lap carried by upstanding spindle. Alternately, spindle is operable by oscillating drive when lap is radially retracted. Toroidal or spherical laps having a large range of variance in two dimensions, i.e. curvatures, are thus obtained by using relevant cutter and lap locations, as well as appropriate drive settings. Concave laps are produced by exchanging locations of lap and cutter so workpiece is carried by vertical-moving arm.

    摘要: A programmable machine for automatically cutting and/or resurfacing a selected arcuate pattern upon either a convex or concave lap, particularly such laps as may then be used for forming and polishing opthalmic lenses. A lap positioning unit and a cutter positioning unit are located respectively on adjacent upright and horizontal supports so as to bring the lap and cutter into mutual engagement, each unit initially being longitudinally adjustable from a respective pivot point by a selected amount so as to determine the particular arcuate curvature obtained, which curvatures jointly form the two-dimentional arcuate pattern chosen for the lap face. In operation, the lap is oscillated vertically and a rotary milling cutter is driven back and forth transverse thereto. Each unit is associated with a longitudinal cam plate or guide of distally converging taper, the opposite edges of which serve to jog a contact roller which triggers a corresponding reversing switch, thus automatically limiting the length of swing of the particular unit. The arcuate stroke length of the oscillating lap and of the cutter are thus correlated with the amount of displacement from the particular pivot point.To change between concave and convex work surfaces, the lap-carrying unit and the cutter-carrying unit may each be rotated 180.degree. on their respective axes so that when brought together again each faces the opposite direction. An electric motor drives the rotary milling cutter, the oscillatory movements of the positioning units being effected hydraulically, and electric programming means enabling the machine to continue the set pattern to the end of a run and then return to starting position before shutting itself off, thus enabling an operator to replace successive workpieces (laps) in a series of such machines operating in sequential cycles.

    摘要: A grinding assembly for shaping work pieces that includes one or more grind spindles. Each of the grind spindles include two independent grinding wheels driven by a single spindle drive. The grind spindles translate horizontally to perform both edge and face grinding with a single grind spindle. A non-contact position sensor in a work spindle measures work spindle displacement during grinding and provides feedback to the grind spindle to regulate the force imparted on the work piece by the grind spindle. In variations, an abrasive wheel disposed radially with respect to an axis of spindle rotation is utilized to perform edge grinding of the work piece. In other variations cleaning, polishing and grinding are carried out in a single grinding assembly. In yet other variations, a wheel dressing apparatus is utilized to dress the wheel when one or more forces to maintain productivity of the grind wheel exceed a threhold.
