Step 2 processes auxiliary glass, chooses the moderate glass material of hardness, is by its milling, a curvature radius with it is to be added
The non-processing face size of part is identical, and symbol is on the contrary, another curvature radius is identical as the non-processing face size of parts to be processed, symbol
Identical equal thick lenses；
Step 3 bonds auxiliary glass and parts to be processed；
Step 4 polishes the parts to be processed bonded using numerical control efficient polissoir, modifies first to polished die,
Ensure polished die N, the parts to be processed that clamping has bonded, after next ensures the environmental condition of polishing, running device is polished
10~15min；
Step 5 after polishing, removes auxiliary glass, cleans part, send and test；
Step 6 is transferred to next procedure.
Preferably, environmental condition is temperature in the step 4: 22 DEG C~26 DEG C, relative humidity: and 30%~70%, polishing fluid
Temperature: 24 DEG C~26 DEG C；When polishing, according to polishing effect, polish pressure 0.25bar~0.35bar, the speed of mainshaft are adjusted in real time
80r/m~200r/m, buff spindle revolving speed 80r/m~200r/m, polished die revolving speed 100r/min~300r/min.
Preferably, in the step 3, auxiliary glass concave surface and parts to be processed convex surface are bonded using yellow wax.
The invention has the following advantages:
The present invention solves easily-deformable lens, the larger problem of burnishing surface face deformationization in application numerical control efficient equipment polishing,
By bonding auxiliary glass on easily-deformable lens, composite part center thickness and edge thickness gap are reduced, to substantially drop
Easily-deformable lens are become on-deformable lens by the feature of such low lens face shape mutability in efficient polishing, final to reduce
Difficulty of processing finally makes such part the processing of design objective can be rapidly completed on efficient polissoir.It is relatively classic to throw
Light technology, polishing efficiency can be improved 3~5 times, prevent the unstable problem of classic polishing process, and part surface shape consistency is good,
Successfully solves such easily-deformable series-produced bottleneck problem of lens.
