<p>A universal head (4) changes the orientation of a tool (5, 31) freely and machines a workpiece (3) with the tool (5, 31) in the changed orientation. The universal head (4) comprises a universal head body (6), for swiveling movement, including a swinging unit (30) and an attachment (7) detachably mounted on the swinging unit (30) with a rotating tool (5) removably mounted on the attachment (7). The universal head (4) has, and simultaneously offers, the advantages of both a universal head, which allows the tool to change its orientation freely for machining a workpiece, and an attachment which allows the tool to be brought closely to the workpiece for machining the workpiece. The universal head (4) does not require a process of installing itself on and removing itself from a universal head support (10).</p> |
