ABSTRACT:
Ophthalmic lens manufacturing equipment includes lens die assemblies constructed to accommodate fragile, high quality glass lens dies. The lens die supports of the assemblies provide a series of grooves of critically small widths on their interface surfaces to apply vacuum pressure from an external source to the backs of the lens dies and thereby hold them in place. The vacuum securement also enables rapid lens die changeover using robotic arms.
