WERKZEUG ZUM AUSSENKONTURENFRAESEN VON POLYCARBONAT-BRILLENGLAESERN AUF EINER KONVENTIONELLEN SCHLEIFMASCHINE.

摘要

A machining and bevelling tool, which is adaptable to a standard grinding machine for ophthalmic glasses, includes a metal body (1) having in its periphery a V shaped groove (2) and at least two teeth (3) each in the form of a small inserted plate (4) presenting a notch of corresponding V shape which protrudes in said groove (2), a shallow adjacent recess (8) being provided in front of each tooth (3), considering the direction of rotation of the tool. The diameter of the tool is larger than that of an ophthalmic glass, and substantially equal to that of a standard grinding wheel for ophthalmic glasses.
