A machine (10) is described for manufacturing buttons comprising a base (12); a container device (14), supported on the base (12), capable of containing a plurality of disc-shaped elements (100) to be machined on the machine (10); un supplying device (16), operatively connected to the container device (14), capable of selectively supplying, by fall through a channel, a single disc-shaped element (100) at a time to a clamp gripping device (18); a clamp gripping device (18), fixed to the base (12), provided with two opposite and coaxial gripping shafts (22, 24), which block the disc-shaped element (100) by pressure, acting onto its two opposite and parallel surfaces, and set it into rotation; and a machining device (20), fixed to the base (12) and arranged adjacent to the clamp gripping device (18), capable of machining the outer circumferential edge of the disc-shaped element (100) held and made to rotate by such a clamp gripping device (18). The clamp gripping device (18) is provided with a self-centering positioning system (52) of the disc- shaped elements (100), arranged below the supplying device (16) and capable of positioning each disc-shaped element (100), independently from its outer diameter, substantially coaxially with respect to the opposite gripping shafts (22, 24) of the clamp gripping device (18). |
