Tool-holder cylinder and abrasive unit for surface machining of stone or ceramic materials

Abstract

Described is a tool-holder cylinder (100; 300) for supporting abrasive tools, designed to be attached to a head (71) of a machine tool for surface machining of ceramic and/or stone materials, wherein said head (71) is configured to rotate about a first axis (x) substantially parallel to a surface to be machined and coinciding with the axis of central symmetry of said cylinder (100; 300), said cylinder (100; 300) comprising an upper surface (120; 320), a lower surface (130; 330), and a side surface (160; 360) parallel to the first axis (x) and on which are formed a plurality of seats (111; 311) designed to house said abrasive tools by means of a dovetail coupling, characterised in that said seats (111; 311) have a first tapering which extends perpendicularly and away from the first axis (x), and a second tapering parallel to the first axis (x). The invention further relates to an abrasive unit comprising a cylinder of the said type and to a machine comprising said abrasive unit.
