DIAMOND GRINDING MACHINE FOR JEWELLERY, GOLDSMITH, SILVERWARE AND FASHION JEWELLERY PRODUCTS AND RELATIVE METHOD OF DIAMOND GRINDING

摘要

Described is a machine (1) for mirror polishing jewellery, goldsmith's, silversmith's and costume jewellery products and the relative processing method. The machine (1) comprises, on a load-bearing frame (2), at least a first robotic arm (3) designed to be moved by a central data processing unit along several axes, in a plurality of rotational movements. The arm (3) is for supporting a tool holder head (4) equipped with a tool (14) for processing at least a series of objects (9) to be mirror polished which are substantially identical to each other. There are also supporting means (7', 7'', 17', 17'') for stopping each of the objects (9) of said series, in the operating position and for rotating along a relative axis (20). The machine (1) comprises means (5) for detecting the outer surfaces of an initial object (9') of the series of objects (9), connected to the unit for storing the shape of the initial object (9') and/or for controlling the outer surfaces of each of the objects (9) to be mirror polished. The head (4) is designed to actuate the tool (14) alternately along a direction of movement (10), in such a way that it can translate in one direction or the other independently of the plurality of rotary movements of the arm (3). The detection means (5) are moved by the unit along guide means (6) formed on the frame (2) between a rest position of the detection means (5) and a scanning position of the initial object (9') or of one of the objects (9) to be mirror polished.
