processo, ferramenta e dispositivo para o acabamento superficial de peças a serem trabalhadas de materiais não duro quebradiços na produção ótica.

摘要

The plastic spectacle lens (L) is subjected to a milling operation that is followed by a rotational machining operation, in which a rotational cutting edge of a tool (18) is applied tangentially to a specific surface (F) to be machined on the lens, by controlling relative movement of the lens and the tool in linear axes (X,Y) and by swiveling the tool. Independent claims are also included for the following: (1) tool for surface machining of plastic spectacle lens; and (2) device for surface machining of plastic spectacle lens.
