Abstract: In a machine tool (10) with a machine base (11), a working area (14), in which workpieces (13) are machined, and a device (25), which receives chips (24) formed during machining of the workpieces (13) from the working area (14) and conveys them onward, at least one tunnel (31, 33) provided for receiving one end (39) of a chip conveyor (38) is provided in the machine base (11), which tunnel extends at least to below the device (25) and is there of upwardly open (28) design.

Abstract: The machine tool includes a spindle rotor, a tool receptacle and a clamp for clamping a tool in the tool receptacle. The clamp is moveable in the direction of the spindle axis by a spindle drive which is actuated by rotation of the spindle rotor. A spreading member is provided in the tool receptacle for positive gripping and clamping of the tool. The spindle drive preferably includes an externally threaded section on the spreading member and an internally threaded section on the tool receptacle, the latter being non-rotatably joined with the spindle rotor.

Abstract: A machine tool comprises at least one spindle (13). Tool changers (27) for exchanging tools (31) are associated with said spindle (13). The spindle (13) is fitted with a facing head (60). The facing head (60) comprises means for numerically controlled displacement of a facing tool (69) in a direction (r) perpendicular to the axis (23) of the spindle (13). The tool changer associated with the spindle (13) is configured for exchanging facing tools (69) (FIG. 2).
