A rotating table apparatus using a cam mechanism and having a higher precision than a conventional rotating table is realized. A rotating table apparatus having a driven shaft supported by a housing and driven by a driving means, and a rotating table which is rotatingly driven by said driven shaft using a cam and cam followers, wherein the rotating table apparatus has an opposing surface which opposes an end surface of the rotating table in a direction along a rotation shaft of said rotating table, and oil is intervened in between the opposing surface and said end surface.

A machine tool that comprises a fixed bed, a pair of tool posts mounted on the fixed bed on a side closer to an operator and a carriage mounted on each of the tool posts is disclosed. A headstock is provided on a side of the fixed bed farther from the operator so that a workpiece disposed in the headstock is subjected to a cutting process by moving the carriages and the tool posts relative to the workpiece. The machine tool also includes a headstock base having the headstock disposed thereon. The headstock base is structured and arranged so as to be movable between a workpiece machining position where the workpiece can be machined at a position farther from the operator and a workpiece loading and unloading position where the workpiece can be loaded and unloaded at a position closer to the operator.

The present invention relates to a pillar drilling machine comprising a drill head, which is supported on a pillar, and a base for supporting said pillar, as well as a power supply strand leading to said drill head. In order to lead the power supply strand to the drill head as safely as possible and with little risk and hindrance and in order to guarantee simultaneously a good functionality and good handling properties, an accommodation chamber is provided, which extends substantially longitudinally in the interior of said pillar, said power supply strand being arranged, at least sectionwise, in said accommodation chamber such that it extends substantially longitudinally.

A stage (10) for a workpiece comprises an upper member (13) for carrying a workpiece holder (15), a lower member (12) and two guide assemblies (16) mounting the upper member (13) on the lower member (12) to be rectilinearly displaceable relative thereto. The lower member (12) is in turn preferably similarly mounted on a fixed base plate (11) by further such guide assemblies (16), the two members (12, 13) being respectively displaceable in an X direction and a Y direction. At least one of the members (12 or 13), but preferably both members and also the base plate (11), is made of a machinable lightweight composite, for example aluminium alloy and silicon carbide, having a coefficient of thermal expansion not exceeding that of the principal material of the guide assemblies by more than substantially 50%, preferably by no more than 30 to 35%.

A machine tool is structured enhance rigidity of a slide member opposing to a cutting force acting on a tool spindle with no extra increase in weight, thereby intending to lighten the slide member. The machine tool comprises a tool spindle rotating around an axis extending along an Z-axis, a slide member slidable in at least one of the X-axis, Y-axis and Z-axis directions and a guide apparatus having a straight rail and movably supporting the slide member on the guide rail and disposed such that three supporting points for supporting the slide member form vertexes of a triangle as seen from the X-axis direction. Further, in another construction, two sets of linear guide mechanism and a linear motor for guiding each of an upper portion and a lower portion of a gantry are respectively disposed between a lower surface of the gantry and a base, and between a front surface of a cross beam and an upper back surface of the gantry, so that the cross beam does not lap over the upper surface of the gantry.

A logical structure of a frame of a machine tool enables displacements of a movable mechanism, such as a slide, along three axes X, Y, and Z. A first pair of parallel transverse horizontal guide rails is disposed in a vertical plane and enables horizontal displacements of the slide along the X axis. A second pair of parallel lateral vertical guide rails is disposed in the same vertical plane and enables vertical displacements of the slide along the Y axis which is perpendicular to the X axis. A third pair of parallel longitudinal horizontal guide rails is disposed in a horizontal plane and enables horizontal displacements of the slide along the Z axis which is perpendicular to both the X and Y axes. A front portion of the slide is unencumbered by drive mechanisms and passes through a telescopic cowling which follows movements of the slide and separates a drive station from a machining station.
