A device (1) for the manufacture of replicas from patterns, i.e. insert bodies, such as dental fillings, dental crowns, human joints and the like, by a method of copy milling or profile grinding a blank (2) with the aid of a pattern (3). Two spindles (4, 5), one pattern-supporting spindle (4) and one blank-supporting spindle (5), driven in synchrony and positioned in mutually aligned relationship, are each provided at their ends with an attachment means (6, 7). A sensing unit (8) provided with a sensing tool (9), and a machining unit (10), provided with a machining tool (11), both are mounted in a holder arm (12) which is movable relative to the pattern spindle (4) and the blank spindle (5). The holder arm (12) is rotatably mounted in a link (15) which in turn is rotatably mounted in end walls (17, 18) mounted in a carriage (20). The pivot shafts like the carriage movement are parallel with the axis of alignment of the pattern and blank spindles (4, 5). The device makes possible manual as well as automatic machining and upon automatic machining it may shift automatically from coarse shaping to precision-shaping.
