FINE-TUNABLE TANG FOR POLISHING AND FACETING SMALL DIAMONDS

摘要

A fine-tunable tang for use in the process of shaping of small diamonds that facilitates performing slight changes in the angle of a dop. The tang (30) comprises an elongated body (34) that widens towards its rear end (36) so as to insure stability, and an angle adjustment member (56) located towards its front end, to which is attachable a small diamond dop (58) . The angle adjustment member (56) comprises a spring-loaded mechanism acting on a mediator (110) contained within a housing (112) and operated by an adjustment screw (124), such that rotation of the screw causes fine angular adjustment of the dop (58). The tang (30) may further include a screw-operated leveling member (54) situated between the angle adjustment member (56) and the elongated member. The tang further comprises adjustable legs (40) for horizontal leveling of the tang.
