A processing device suitable for processing multiple lens blanks into a finely ground product, the processing device including two processing fixtures, each including a fixture body with a curved surface. There are three grooves having centers disposed on the same circumferential surface. One of the processing fixtures corresponds to the inner surface of the groove as a flat surface, and the other processing fixture corresponds to the concave surface of the groove as a curved surface. The invention also discloses a method for processing a plurality of lens blanks into a finely ground product by using the processing device. The invention can directly perform the fine grinding processing of multiple cylindrical lens blanks, thereby eliminating a milling process and reducing the production cost while meeting the required thickness, radius of curvature and appearance of the finished product.
A processing device for processing a plurality of lens blanks into finely ground products, said processing device comprising two processing fixtures, each of said two processing fixtures comprises a fixture body comprising a curved surface, three grooves each comprising a center, said three grooves are configured such that said centers are disposed on said curved surface of each said processing fixture, wherein a first of said two processing fixtures comprises a surface of each of said three grooves that is a flat surface and a second of said two processing fixtures comprises a surface of each of said three grooves that is a curved surface.
