An interior of a machine tool and a machining area are divided for communication by a labyrinth. The machining area is covered by a cover. Air discharged from an air bearing flows from the machine tool interior into the machining area through the labyrinth. The cover for the machining area is provided with an exhaust unit for discharging the air from the air bearing or a mist produced in the machining area to the outside of the machine tool.

When a slide member mounted with a tool reciprocates on a guide member reach one end and the other end positions of the guide member, permanent magnets provided on the guide member and the permanent magnets provided on the slide member repel each other to give the guide member forces for reversing its moving direction. The guide member is provided to be movable with respect to a base and repulsive forces between permanent magnets provided on the base and permanent magnets provided on the guide member are used to retain an axial position of the guide member.

A pocket provided with fastener includes a pocket formed by a base cloth and an outer cloth disposed atop the base cloth whose bottom and both lateral sides portions are sewed to the base cloth, a top portion thereof being open so as to create a pocket portion; and a fastener detachably provided on the outer cloth, with at least one attachment hole for mounting the fastener formed in the outer cloth. The fastener includes a planar base portion; a mounting belt portion one end of which is fixedly mounted on the planar base portion for detachable attaching the fastener to the pocket through the attachment hole; a fastening projecting portion that projects above the base portion and fastens an object to be fastened; and a lid member that opens and closes to maintain a state in which the object to be fastened is fastened to the fastening projecting portion.

A pulse generation means that generates a pulse each time an XY movable member moves linearly by a certain amount relative to a base is provided. A workpiece and a light and dark pattern member are provided on the base. A tool, a light and dark pattern scanning sensor that scans the light and dark pattern and outputs a scanning signal, and a cutting means that moves the tool with respect to the workpiece in a cutting depth direction, orthogonal to the linear motion direction, are provided on the XY movable member. While the XY movable member moves relative to the base, the tool is moved by the cutting means in accordance with a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and the pulse from the pulse generation means to perform machining.

A microscopic positioning device having machine rigidity and being capable of achieving nano-order positioning accuracy and a method of compensating tool position and orientation. A driving unit comprises two piezoelectric elements P1 and P2 arranged into alignment along an expanding/shrinking direction. Both ends of the piezoelectric element P1, facing in the expanding/shrinking direction, are fixed to a base member and a movable member, respectively. The other piezoelectric element P2 is fixed to the base member only at one end. A gap L is formed between the piezoelectric element P2 and the movable member. Where expanding displacement amounts of the piezoelectric elements P1 and P2 are a1 and a2, respectively, voltage applied to the piezoelectric elements P1 and P2 is so controlled to satisfy an equation, a1+a2=a≧L. It is possible to position the movable member at a position within a maximum stroke a in the nano-order. The driving units may be arranged in the orthogonal directions, thereby providing the positioning device with two degrees of freedom, and further providing six degrees of freedom including rotation axes.

摘要:
When an excitation of a servo motor is released due to an emergency stop, a power outage, or another operation performed on a positioning device, the positioning device uses air supplied from an air supply source to vary pressure of an air balance, which cancels a self-weight of a vertical axis driven by the servo motor, thereby moving the vertical axis.
摘要:
A fluid bearing structure with uniform depths of bearing concaves and a method of forming the bearing concaves in the fluid bearing structure. Pipe parts are inserted into through holes formed in the bearing base to form fluid spout holes for spouting fluid between confronting bearing surfaces. Bearing concaves are formed around the fluid spout holes. The bearing base and the pipe parts are made of different materials. A coating layer is formed on the bearing base and the pipe parts by an anodic oxidation process. Thickness of the coating layer on the bearing base is different from thickness of the coating layer on the pipe parts since the base member and the pipe members are made of different materials. The material on which a coating layer grows quickly is selected for the bearing base and the material on which a coating layer grows slowly is selected for the pipe parts.

A contact type measurement device performs measurement with displacement of a probe, while a contact member attached to the probe is in contact with an object to be measured. Data on the relationship of a contact force of the probe to the object to be measured with an angle between the central axis of the probe and the direction of gravity, the amount of displacement of the probe, and a fluid pressure for applying a pushing-out or pulling-in force to the probe is stored in advance and, on the basis of this data, the fluid pressure or the amount of displacement of the probe is controlled to automatically and precisely adjust a fine contact force of the probe to the object to be measured.
