Abstract

112,349. Taylor. W. March 1, 1917. Addition to 15375/15. Lenses and curved surfaces, grinding and polishing.-In the application of the method of " terrace grinding " as described in the parent Specification to the formation of spherical surfaces upon glass and like materials, the edge of the abrasive wheel is set so that it moves across the face of the rotating work, there being a slow movement of approach between the work and the wheel, the axes of which are set at the requisite angle to give the required radius. The rough grinding is accomplished with the wheel axis set relatively to the work axis out of one common plane so that the wheel operates to one side only of the axis of the work. The finishing operation is accomplished by the wheel set with its axis substantially in one plane with the work axis. The annular grinding- disk e is formed with a bevelled surface e<2> to give the necessary clearance and an active surface e<3> to give the abrupt step. The disk is carried on a driven spindle f in bearings in a yoke frame h supported on alined pivots i, which are mounted upon a slide rest constructed as described in Specification 15377/15. The frame can be tilted about these pivots by a screw n passing through a nut o on the frame, to move the axis e<1> of the grinding-disk out of the plane of the axle c' of the work-spindle. The rough grinding is accomplished with the axis c<1> set at an angle to the axis of the work-spindle. During the operation, the axis is gradually lowered until, for the finishing operation, it is in the plane of the work-spindle. The axis of the pivots i passes through the axis of the work-spindle at the active point of the grinding-disk. The work-spindle axis may be tilted in place of the grinding-disk axis. A separate wheel may be used for the finishing operation and may be mounted as described in Specification 15377/15, and, in this case, a number of work-spindles may be mounted upon a turret arranged and operated as described in the same Specification.
