Benefits of technology

The present invention provides a blocking piece for holding optical workpieces, such as spectacle lenses, for processing. The blocking piece helps solve previous problems in the art and enables production of high-quality optics with reduced environmental impact and lower cost. The blocking piece can be used during various processing steps and is compatible with existing machining equipment. The invention also provides a set of blocking pieces and a method for manufacturing spectacle lenses using the blocking piece.

Problems solved by technology

However, such a single throw away part cannot be recycled.
Alternatively the most usual concept of having a base portion made of hard metal with a lens supporting part made of a specific low temperature melting alloy is prone to environmental issues as well.

Abstract

The invention refers to a blocking piece, comprising at least two parts, at least one part being designed for multiple use and at least one part being designed for single use, wherein a surface for supporting one face of an optical article to be blocked is constituted at least in part by the reusable part and at least in part by the single use part.

Description

CROSS-REFERENCE TO PATENT APPLICATIONS[0001]The present application is related to U.S. patent application Ser. No. 14 / 281,141, entitled Multimaterial Block Piece, and filed on May 2, 2014. The entire disclosure of the foregoing application is incorporated herein by reference.[0002]The entire content of the foregoing application is incorporated herein by reference.TECHNICAL FIELD OF THE INVENTION[0003]The present invention generally relates to a workpiece support block (“blocking piece”) for supporting an optical workpiece during the processing thereof. In particular, the invention relates to a blocking piece for holding a spectacle lens for processing thereof, as used in prescription workshops in masses, that is to say production workshops for manufacturing individual spectacle lenses from customary materials (mineral glass, polycarbonate, PMMA, CR 39, HI index, etc.) according to a prescription. The invention also concerns a set of blocking pieces and a method for manufacturing spe...
