SPECTACLE LENS TRIMMING MACHINE WITH A ROTATING TOOL CARRIER ON WHICH ARE MOUNTED SEVERAL WORKING TOOLS

摘要

#CMT# #/CMT# The machine has shafts (12, 13) for rotating a solar/corrective ophthalmic lens (100) around a rotational axis (A3), and a tool holder (20) rotated around a rotational axis (A20). A trimming tool (21), a finishing tool (22) and a piercing tool are rotatively mounted on the holder around three tool axes. A gear motor assembly (15) controls relative spacing mobility between the axes (A3, A20). Inclination units permit relative pivoting of the holder relative to the axis (A3) around a rotation axis (A0) transversal to the axis (A3), and are constituted of an endless screw (31) and a wheel (32). #CMT# : #/CMT# An independent claim is also included for a method for trimming an ophthalmic lens of spectacles. #CMT#USE : #/CMT# Machine for trimming a solar or corrective ophthalmic lens of spectacles. #CMT#ADVANTAGE : #/CMT# The design of the trimming machine permits reduction of the number of parts of the machine, and reduces mobility of the tool holder, thus increasing the diversity of processing of the ophthalmic lens, and reducing cost of the machine. The design of the trimming machine permits precise trimming of the lens, and reduces the time of trimming of the lens by an optician. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a trimming machine in which inclination units of a tool holder appear.
