Machining device for machine-assisted production and machining of dental workpieces

A machining device for the machine-assisted production and machining of dental workpieces (16), at least one of the workpieces (16) being clamped in at least one workpiece retainer (11) which can be raised, lowered and rotatably driven and which is positioned on a rotational axis (9), and wherein the at least one workpiece retainer feeds the at least one workpiece (16), for the purpose of machining the at least one workpiece while the at least one workpiece (16) is clamped in the at least one workpiece retainer, to at least one tool spindle (4, 5, 6) that is rotationally driven and that has at least one tool (7) secured thereto,

• wherein the at least one workpiece retainer (11, 11a, 11b) is configured as a multi-axis robot with at least five degrees of freedom, on one side of the at least one workpiece retainer (11, 11a, 11b) is arranged at least one tool retainer (2, 2a, 2b) that is provided with the at least one tool spindle (4, 5, 6) and the at least one tool (7), and
• wherein on an opposite side of the at least one workpiece retainer (11, 11a, 11b) are arranged:
• (i) a tool storage (34), and (ii) a workpiece changer (22, 22a, 22b) in which the workpieces (16, 16a, 16b, 16c) to be machined are received such that the workpieces can be exchanged between the at least one workpiece retainer (11, 11a, 11b) and the workpiece chancier (22, 22a, 22b),
• wherein the at least one workpiece retainer (11, 11a, 11b) further comprises (i) a device at a head portion of the at least one workpiece retainer (11, 11a, 11b), which device is for clamping the workpiece (16) to be machined;
• and (ii) two gripper forks (32, 33), each gripper fork (32, 33) being configured to receive a respective tool, so as to enable the multi-axis robot to exchange tools between the tool storage (34) and the at least one tool spindle (4, 5, 6).
