    Abstract: A device for treating or acting on workpiece surfaces by means of an actuator, such as a cutting or engraving laser or a nozzle for applying oils, paints, adhesives, dyes, or etchants is disclosed. An ultrasonic levitation force field is generated by means of a sonotrode, which is coupled to the actuator into a working unit, such that the movably suspended working unit is supported on the workpiece surface in a hovering manner. The ultrasonic levitation force field allows a highly precise positioning of the working unit relative to the workpiece surface so as to allow a precise treatment or machining of the workpiece surface.

    Abstract: A machine has a frame structure for moving a machine head in one or more spatial directions. The frame structure comprises an actuator and an air bearing for moving the head. The machine also comprises a compressed air feed connected to the air bearing for providing a compressed air flow. A restrictor defines the compressed air flow to the air bearing. The machine has a first operating state, in which a high compressed air flow is defined and in which the actuator can be actuated. The machine has a second operating state, in which a compressed air flow lower than the high compressed air flow is defined. In the second operating state, the actuator is secured against actuation from a closed-loop position controller, while the closed-loop position controller is maintained in operation.

    Abstract: In a vertical lathe of an open side column type, a pair of linear guides (65,66) arranged in parallel in a cross rail (62), and a space portion (67) is formed between them (65,66). A saddle (90) is supported by the linear guides (65, 66) above the space portion (67) and moved in an axis direction (X axis). A ram (120) is suspended through the space portion (67) and moved in a vertical direction (X axis). A rotary driving disc (34) fixed on the table rotation driving shalt (33) is connected to a rotary table (30) by plural torque transmission pins (37) in torque transmission relationship. Thereby, the rotary table (30) rotates in carrier method. A tool holder (151) is rotatably driven at an optional angle position (B axis position) by a B axis servomotor (163) about a horizontal axis. The tool holder (151) is clamped at an optional rotation angle position by a thrust static pressure bearing under oil-pressure supply to one of thrust static pressure portions. The tool angle is changeable by using the B axis servomotor (163).

    Abstract: An electric path (E) is formed by connecting a spindle (11), a tool (12), a table (4), a base (2), a column (5) and a housing (13) including a capacitor (C0) having the spindle (11) and the housing (13) as electrodes, and electric current is sent to the electric path (E) by a current generator (51). An electro-capacitance change is detected by measuring a current value in the electric path (E) by an electro-capacitance detector (52) to detect a state of a bearing gap between the spindle (11) and the housing (13). No multiple sensors are necessary and the spindle state detector (50) can be simplified.
