    摘要: A machine, for working wood panels (2) or similar, has an air-cushion table (13, 39, 41) for supporting at least one panel (2); the table (13, 39, 41) housing a chamber (13a), which communicates with the outside through a number of holes (16) formed through the table (13, 39, 41), and is connected pneumatically to a compressed-air source (S) for supplying the chamber (13a) with a given amount of compressed air, which is supplemented with an additional amount of outside air drawn in by at least one air-amplifying device (15).

    摘要: An air balance structure that compensates for the weight load of a movable member driven in a straight line along the vertical axis, with a simplified structure and at reduced cost. The box-shaped movable member has an open bottom that accommodates the stationary member therewithin, in which state the movable member is movably supported in the vertical direction by an air bearing created using a gap between the stationary member and the movable member. An air balance chamber that contains pressurized air is formed inside the movable member. After pressure-adjusted air is supplied from the outside to the gap from a jet port through a pipe inside the stationary member, the air flows into the air balance chamber. This flow seals the pressurized air inside the air balance chamber. Pressurized air exhaust is exhausted externally from an exhaust port through a pipe and a flow adjusting device.

    摘要: A machine tool (1) is provided in which a movable member (30) guided by a hydrostatic slideway (21,31) is held in a predetermined attitude. A vertical machining center as the machine tool includes a spindle head (30) supported on a front face of a column (20) in a vertically movable manner. A hydrostatic slideway (21,31) for guiding the spindle head includes a slide rail (31) provided on the spindle head (30) and a slide guide (21) provided on the front face of the column (20). A pocket is provided in a lower end portion of a slideway of the slide guide on the side of the column. Pressurized oil is supplied into the pocket at a pressure which is gradually increased according to a downward movement distance of the spindle head from the uppermost position.

    摘要: The present invention relates to an arrangement for compensating for dynamic effects of a slide mounted on a beam via an air gap. Input air pressure (Pin1 and Pin2) is delivered to the air gap. A bearing cushion arrangement (3, 4) compensates for the limited pressure rigidity of the air gap, by equalising air pressure in air gap (11, 12) between beam and bearing cushion arrangement, so as to compensate for rotation about the Y-axis.
