Abstract: A process is for material-removing machining, on both sides simultaneously, of semiconductor wafers having a front surface and a back surface, the semiconductor wafers resting in carriers which are set in rotation by means of an annular outer drive ring and an annular inner drive ring and being moved between two oppositely rotating working disks in a manner which can be described by means of in each case one path curve relative to the upper working disk and one path curve relative to the lower working disk, wherein the two path curves after six loops around the center have the appearance of still being open, and at each point have a radius of curvature which is at least as great as the radius of the inner drive ring.

Abstract: An eyeglass lens grinding apparatus, which is designed to process an eyeglass lens so that the lens fits into an eyeglass frame. Frame shape data of an eyeglass frame is input, and a lens edge position on the lens is measured based on said frame shape data. Lens processing data is calculated based on the lens edge position and the frame shape data. The processing data is stored. The grinding wheels are controlled to process a plurality of lenses consecutively based on the same processing data until a signal requiring different processing data is issued. If a next set of lenses are to be processed, i.e. a different processing data is required, a made is switch to measure a lens edge position to newly obtain processing data.

Abstract: A method and apparatus for machining a custom-shaped dental restorative part from a blank of dental material yield the entire part in a single operation, and include a workpiece being mounted on a support member which facilitates rotation and axial movement of the workpiece. A separating disk is used for almost the entire machining operation, and an additional tool in the shape of a burr can optionally be provided to shape more elaborate pieces. The disk and burr are supported by a tool holder which is supported for movement parallel to and rotationally about an axis. The disk and burr are powered by a closed loop fluid supply arrangement. A tool velocity sensing scheme is utilized for adaptive feed and to compensate for tool wear. The machining mechanism and associated control circuitry are enclosed in a common cabinet so as to provide a mobile unit suitable for use in a dentist's office.

Abstract: The time to grind a workpiece can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength considerations require, and which may therefore be less than the axial length fo the region to be ground providing a work rest or work steady to increase the workpiece stiffness if required, and performing a succession of plunge grinding steps so as to grind the whole of the said axial region. Typically the grinding wheel is an electroplated CBN wheel, and the width of the grinding wheel selected is the narrowest permissible given the desired feed rate and motive power available. A grinding machine is disclosed comprising a wheelhead having mounted thereon a grinding wheel whose width is not substantially greater than that dictated by structural and strength requirements, programmable indexing means to enable the relative positions of the wheelhead and workpiece to be adjusted in a sequence of steps to achieve a sequence of plunge grinds, which may or may not overlap, to enable a region of the workpiece to be ground, the axial extent of which is greater than the width of the wheel, and wheel feed means and control means by which the feed rate is controlled, whereby the wheel feed rate is similarly programmable to enable a feed rate to be achieved which is limited only by the peak and RMS power capabilities of the wheel spindle drive motor, so that the rate of material removal is as high as is compatible with the power capabilities of the machine during each plunge, thereby optimising the total cycle time for grinding.

Abstract: A wave beveling machine is disclosed which produces a wave bevel on a glass work piece. The machine includes a feed path that is adapted to receive a glass work piece and which includes a plurality of spaced-apart treatment heads adjacent the feed path and adapted to sequentially engage the edge region of the work piece as the work piece is moved along the feed path. Each of the plurality of heads includes at least one contact region adapted to contact the edge region of the work piece, and one or more of the heads is adapted to abrade glass from the edge region when in contact with the edge region. The machine further includes a treatment head positioning system adapted to cause the contact surfaces of the plurality of heads and the edge region of the work piece to be engaged and cyclically moved in an oscillating path with respect to each other to produce the wave bevel on the edge region. The machine may further include one or more conveyors that support and move the work piece along the feed path. Furthermore the heads may be mounted on a single carriage, on which they move or are engaged as a unit, or may be independently mounted, wherein they may each be controlled and positioned by the treatment head positioning system independent of the rest of the plurality of heads.
