A cutting machine includes a processing chamber provided with a cutting device to cut a cutting object retained by an adaptor, a cleaning chamber provided with a cleaning device to clean the adaptor, and a conveyor to convey the adaptor to the processing chamber and the cleaning chamber.

A machine tool including a fixed cover and a movable cover for covering at least part of a machining region includes a cover control device that includes a driving circuit for driving the movable cover, an abnormality detection device that detects an abnormality while the movable cover is driven, a self-diagnosis device that performs evaluation on whether the abnormality detection device is normal, and an output device that outputs a result of the evaluation by the self-diagnosis device. The self-diagnosis device is configured to perform the evaluation on whether the abnormality detection device is normal based on an operating state of the abnormality detection device at a time when a pseudo abnormality is generated on the movable cover by driving the movable cover via the driving circuit.

The invention relates to a dental machine tool, in particular a dental milling machine (10), having a tool (12) that is changeable in particular via a tool bank (16), and a workpiece holder (14) for receiving a workpiece such as a dental blank made of ceramic, composite or plastics material such as PMMA, and having a housing (24) which is closable during machining by the machine tool, and having a negative-pressure connection to the housing (24). At least one air nozzle (30) that is fitted on or in the housing (24) is directed towards the workpiece and/or the workpiece holder (14) and/or the tool (12) and/or the tool bank (16) and/or a pane of a front flap of the machine tool. Said air nozzle (30) is equipped with at least one electrode for generating an electric field in the region of the nozzle or in front of the latter, and at least one nozzle comprising at least one electrode is directed towards that side of the workpiece or of the workpiece holder (14) on which the tool (12) machines the workpiece. At least two electrodes of an ionizer extend in a spaced-apart manner over a substantial part of the housing (24), and as a result of the application of an in particular pulsating AC voltage provides spatial deionization of the air flowing through the housing (24) and/or deionization of the surfaces of the workpiece, workpiece holder (14), tool (12) and/or window (28) and of the chips produced by the machining operation.

A confinement cabin has a load-bearing structure, confinement walls connected to the load-bearing structure to delimit an inner space of the cabin, an access opening to the inner space, and a door connected to the load-bearing structure to close the access opening. The door is movable in opening and closing with a pivoting-tilting movement and has a movable arm which at a first end is rotationally connected to the load-bearing structure to rotate around a hinging axis, and a closing panel rotationally connected to a second end of the movable arm to rotate around a tilting axis. Rotation of the panel around the tilting axis is synchronized with rotation of the movable arm around the hinging axis by an elastic transmission system between a first pulley coaxial to the hinging axis and a second pulley coaxial to the tilting axis. Rotation of the panel around the tilting axis is in the opposite direction to rotation of the movable arm around the hinging axis.

The present invention relates to a machine door (2), comprising a door frame (10) having an opening (20), at least three door segments (30), and an actuating means (40), wherein the actuating means (40) can adjust the at least three door segments (30) from a position in the door frame (10) that clears the opening (20) to a position out of the door frame (10) that closes the opening (20). In addition, the present invention relates to a machine (1) having such a machine door (2).

A machine tool is provided with two vertically oriented tool spindles that are arranged to hold tools and that are movable vertically in a first direction and horizontally in a second direction orthogonal to the first direction.
