Abstract
An apparatus (1) for making dental inlays or the like by copy milling a blank (7) based on an original (4) comprises a first spindle (3), which is adpated to hold the original (4) and a second spindle (5), which is aligned with the first spindle (2) and adapted to hold the blank (7). A first sensing unit (8) is adapted to scan the original (4) with a probe (9), and a first milling unit (10) is adapted to mill the blank (7) by means of a shank-end mill (11) to form a dental inlay or the like whose shape corresponds to that of the orignal (4) scanned by the probe (9). A second sensing unit (13) is adapted to carry out a rough scan of the original (4) before the first sensing unit (8) by means of a rotatable disc (14), and a second milling unit (15) is adapted to machine the blank (7), while the disc (14) scans the original (4), by means of a milling disc (16) whose size corresponds to that of the disc (14) to create a shape which roughly corresponds to that of the original (4).
