    摘要： A lens grinding machine with a radially adjustable work holder on which various sizes of lens carriers with lens blanks to be ground, may be mounted and moved at various predetermined radii from a center across the peripheral abrasive surface of a radially adjustable grinding wheel. The center of the radii is situated at the intersection of the rotational grinding plane of the peripheral abrasive surface and the plane of movement of the lens blanks lying on the rotational axis of the wheel and at right angles to the rotational grinding plane whereby concave surfaces with constant primary and secondary radii are ground on the lens blanks. The grinding wheel has a slotted support center with flexible and resilient angularly spaced deformable wall portions of predetermined shape extending from a hub portion to peripheral surfaces supporting bonded abrasive segments containing an alkali soluble abrasive bond and is mounted on an arbor adapted with means to clamp the wheel and vary the shape of the deformable wall portions and radius of the peripheral abrasive surface of the wheel.

    摘要： There is provided a method of manufacturing an optical element having a circular portion and at least one annular zone formed thereon, the circular portion having a circular profile and centered about an optical axis as viewed from a direction of an optical axis, the annular zone having an annular zonal face and a boundary wall face formed concentrically around a periphery of the circular portion, and the boundary wall face linking between the circular portion and the annular zonal face. The method is performed by rotating a workpiece about a rotation axis corresponding to the optical axis, and allowing a sharply pointed front end of a tip to prick the workpiece to a portion corresponding to an angled portion defined by the annular zonal face and the boundary wall face so that the annular zonal face is formed by side edges of a rake face of the tip.

    摘要： A polishing method for machining an optical surface of an optical lens uses a polishing wheel which has a wheel axis and a polishing face. The polishing wheel is moved in relation to the lens over the surface of the latter along a spiral machining path. The polishing wheel is rotated about the wheel axis, and is (simultaneously) rotated about an axis of rotation oriented perpendicularly to the wheel axis. The rotational speed of the polishing wheel about the wheel axis and/or the axis of rotation is reduced at the spiral center of the movement path. A workpiece fixture for receiving an optical lens stands opposite the polishing wheel, with the workpiece fixture and the polishing wheel being mounted movably in relation to one another along a spiral movement path. The rotational speed of the wheel axis can be coupled kinematically to the rotational speed of the axis of rotation.
