(3) at high speed lenses polishing machine sphere is finish grinded and polishing.
(4) with the sphere location, soft mold blocking, the sphere elasticity that promptly suspends location.
(5) the workpiece lacquer disk(-sc) is contained on the flat-grinding machine, ground flat stays the polishing surplus.
(6) on flat-grinding machine, be polished to required fineness.
(7) the workpiece lacquer disk(-sc) is put into the supersonic wave cleaning machine lower wall.
(8) cleaning workpiece.

Below in conjunction with embodiment the present invention is described in further detail.
Procedure of processing:
(1) peripheral size is qualified workpiece blank is clamped on the milling and grinding machine anchor clamps, adopts tubular diamond-impregnated wheel-resin-based, No. 320 drillings of fixed abrasive material, carries out milling, and sphere is shaped, and stays correct grinding and polishing surplus.
(2) incite somebody to action a plurality of workpiece of sphere shaping, use the bonded adhesives of making by 30% shellac, 70% rosin,, be bonded on the circular glass plate, utilize Q0806 jewel brush polishing machine to do the brush rib of sphere seamed edge, root face processing with the planar rigidity location.Root face R is 0.05～0.10mm, realizes disappearing in advance chipping.
(3) the workpiece heat on the circular glass plate that will brush rib is taken off, and cleans the back and goes up dish with sealing wax group, adopts JP12.5 high speed lenses polishing machine to carry out sphere correct grinding and spherical polishing.
(4) sphere location, soft mold blocking, the sphere elasticity that promptly suspends location, referring to Fig. 1,
A, even painting machine oil film 7 on a plate glass 8, a plurality of workpiece 5 planes that processed sphere are arranged in downwards on the glass plate of oiling, promptly do location just without the plane of grinding with it, the about 0.5mm of each workpiece spacing distance, arrange good workpiece group periphery and place the glass blend stop 3 slightly higher than workpiece centre thickness, plate glass 8 edges put retaining frame 2.
B presses sealing wax 90%, and shellac 10% weight matches well binding agent, pour into after the heat fused in the retaining frame 2, to cover blend stop 3 and workpiece 5 serve as in right amount, makes glue line 4, before glue-line 4 is uncooled, other gets a glass plate 6 that equates with glass plate 8 sizes, its one side oil removal treatment is preheated to 60 ℃, and oil removing faces down, be pressed on the glue-line 4, in the retaining frame 2.
C treats the glue-line initial set, does not promptly flow, and removes retaining frame 2, places small-sized hand-operated spinning machine to press on the whole work-piece dish, utilizes the depth of parallelism of the pressure head and the workbench of forcing press, makes two glass plates 6,8 of workpiece plate parallel.
D, release, and remove the plate glass 8 that is used for workpiece 5 first location, form the workpiece lacquer disk(-sc), treat that glue-line 4 solidifies fully after, embrocate acetone in workpiece 5 exposures, remove the part adhesive glue 4 between oil and the dissolving workpiece 5, make glue-line 4 be lower than the about 0.15mm of workpiece, realize suspension sphere elasticity location.
(5) workpiece is contained on the mill of flat-grinding machine, adopts jewel bearing plain grinding processing technology to finish corase grind, correct grinding, reach dimensional requirement, realize the ultra-thin limit of workpiece.
(6) bonding Polyurethane polishing skin on the mill of flat-grinding machine, spray cerium oxide solution between itself and workpiece plate carries out plane polishing, to required fineness requirement.
(7) will process the workpiece plate on plane, and put into supersonic wave cleaning machine and carry out ultrasonic wave cleaning lower wall.
