Abstract: A machine tool for at least triaxially machining work pieces (15) comprises a work spindle (10) and a working area (14) before the work spindle (10). A z skid (23), which is displaceable in the direction of the spindle (10), is disposed above the working area (14), with a work holding fixture (29) being joined to, and suspended downwards from, the z skid (23).

Abstract: An installation for machining work pieces (15) comprises at least a machine tool (36). It is provided with a supply and take-down equipment (41), which is disposed before the machine tool (36) on a side of the working area (14) that faces away from the work spindle (10).

Abstract: A machine tool comprises a rack, a horizontally displaceable x skid and a y skid that is vertically displaceable thereon. The skids are drivable by linear motors which are arranged on the front side of the rack and the face side of the x skid, respectively, and on the rear side of the x skid and the rear side of the y skid, respectively. The same may apply to the x guides and the y guides. The air gaps of the linear motors of each skid are arranged in one plane.

Abstract: A machine tool for the cutting process of work pieces and having at least one horizontally lodged work spindle, preferably for high speed and/or high precision processing. The work spindle displaces on and/or inside a frame-like tool carrier vertically placed on a machine support having slides moving along x-, y- and z-axes. According to the invention, the frame-like tool carrier (3) has an associated frame-like work piece holder (2), which is also placed vertically on the machine support (1). The work piece holder (2) and the tool carrier (3) are interconnected as one single stable unit by one or several connecting elements (8) in the area of their upper horizontal traverse (4, 6).

Abstract: The invention relates to a machining center, wherein at least one work spindle with a preferably horizontal spindle position can be displaced preferably in the direction of X, Y and Z and each work spindle is allocated at least one substantially circular tool store which can rotate around a central axis and which is provided with storage locations so that the working spindle(s) can deposit one or several tools. The invention is characterized in that a) the tool store (2) comprises one or several tool disk(s) (3) which are arranged parallel to each other and grouped together in a drum store, wherein b) the tool disk(s) can be individually or jointly rotated around a central axis (4) which is perpendicular to the spindle axis and c) the tools (5) can be inserted with their tips (6) forward into tool holders (7) in the tool store (2) which are arranged in a tangential to radical direction.

Abstract: A process and machine tool for machining workpieces with two parallel work spindles fitted on a headstock. The distance between the work spindles is altered with the aid of a driven adjuster. The machine tool for machining workpieces, especially for numerically controlled machining centers, has two work spindles (1, 2) fitted parallel to each other on a headstock (3), where at least one work spindle (2) can be adjusted perpendicularly to its axis.

Abstract: A method and arrangement for exchanging a variable number of tool holders in which only one tool holder at a time is brought into working position. The operations involved with accessing a variety of holders, one at a time, to a working position requires movement of minimum mass to the working position adjacent the drive unit--while one or more remaining tool holders are located in a series of accessible independent storage positions or in at least one storage magazine.

Abstract: In accordance with a method and an arrangement for exchanging tool holders of a variable number, only one tool holder is brought in working position, so that only small mass is to be moved, and for the tool holder movable in working position an energy supply and a drive unit is needed, whereas the remaining tool holders are located in a storage position and/or at least one magazine.
