範囲第１項記載のレンズ球面荒摺機。[Scope of Claim for Utility Model Registration] (1) A workpiece shaft upper stand to which a lens holder for fixing a lens to be processed and a motor for rotating the lens holder are fixed, a workpiece lower shaft table fixed to the main body base, and the above-mentioned workpiece. The center line of the sliding part is provided between the upper axis table and the lower workpiece axis stand and is located at a position away from the workpiece axis which is the axis of the lens holder, and the upper workpiece axis stand is connected to the lower workpiece axis stand. a first sliding guide mechanism that guides the workpiece in a direction parallel to the workpiece axis; a grindstone spindle table to which a grindstone spindle for fixing a grindstone and a motor for rotating the spindle are fixed; and the workpiece axis and the grindstone. A grindstone shaft lower stand is provided on the main body base so as to be swingable around a swivel axis perpendicular to the grindstone axis, which is the axis of the shaft spindle, and a grindstone shaft lower stand is provided between the above-mentioned grindstone spindle upper stand and the above-mentioned grindstone spindle lower stand. The center axis of the sliding part is located at a position away from the grinding wheel shaft, and with the grinding wheel shaft aligned with the workpiece axis, the upper grinding wheel spindle is moved in a direction parallel to the grinding wheel shaft with respect to the lower grinding wheel spindle. A lens spherical roughening machine comprising: a second sliding guide mechanism for guiding; (2) Utility model registration claim 1, characterized in that the first and second sliding guide mechanisms are provided with bellows for preventing grinding fluid from entering the sliding guide mechanisms. The lens spherical surface roughening machine described.
