摘要:
An eyeglass lens processing apparatus comprising a processing control unit which performs polishing by controlling a lens rotating unit, a grindstone rotating unit and an axis-to-axis distance varying unit based on an input target lens shape so as to process a periphery of a lens, which has been finished, by a lens margin allowed for polishing by the polishing grindstone. The processing control unit controls the lens rotating unit, the grindstone rotating unit and the axis-to-axis distance varying unit based on a lens rotating speed V1 and the grindstone rotating speed Vw at least at the final rotation of the lens. The lens rotation speed V1 and the grindstone rotation speed Vw satisfy a condition in which an average interval between cyclic stripes appearing on a processed surface of the lens due to height fluctuations of the polishing grindstone is smaller than eye's resolution or is larger than 2 mm.

In an eyeglass lens processing apparatus for beveling a peripheral edge of an eyeglass lens, if the high curve lens processing mode is selected by a mode selector, a computing unit acquires a high curve bevel path for locating the bevel apex on a front surface curve of the eyeglass lens or for locating the bevel apex at a position shifted by a predetermined quantity from the front surface curve toward the rear side on the basis of the edge position information acquired by the edge position detector, thereby providing high curve beveling data for the rear surface beveling grindstone, or for the front surface and rear surface beveling grindstones; and a beveling controller bevels the peripheral edge of the eyeglass lens by the rear surface beveling grindstone, or by the front surface and rear surface beveling grindstones on the basis of the high curve beveling data.
