Abstract:
1. A device for providing a plurality of workpiece ends with a convex surface, said equipment comprising: a holder for holding workpiece ends such that the workpiece ends are substantially and equally raised above a planar surface of said holder; a first elastic grinding surface for grinding and polishing the workpiece ends held by said holder; a driving device for driving said holder or said elastic grinding surface to engage in an eccentric rotation in a constant orientation; a pressure device for providing a predetermined pressure under which the workpiece ends are kept in contact with said elastic grinding surface, thereby enabling the workpiece ends to be ground or polished by said elastic grinding surface; and one or more additional elastic grinding surfaces in addition to said first elastic grinding surface whereby said elastic grinding surfaces are used to grind or polish the workpiece ends in conformity with various specifications, with said elastic grinding surfaces being driven by said driving device to engage in an eccentric rotation in a constant orientation such that said additional elastic grinding surfaces come in contact with the workpiece ends one after another under the same or different pressure provided by said pressure device.
