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).
Claims9
A machine tool for at least triaxially machining work pieces (15), comprising:
- a machine bed (1);
- a first frame (2) joined to the machine bed (1);
- a work spindle (10), which, by means of a work spindle motion unit (13) that is disposed on the first frame (2), is movable on a plane spanned by a vertical y direction and a horizontal x direction, and which is designed for holding a tool (16), and which said work spindle has a rotational axis that extends perpendicularly to said plane in a z direction;
- a working area (14) disposed on the machine bed (1) before the work spindle (10) in the z direction;
- and
- a work holding fixture (29), which includes holding means (32) for a work piece (15) or a fitting piece (31) that holds a work piece (15) and which is disposed in the working area (14);
- wherein a z skid (23), which is displaceable in the z direction, is disposed above the working area (14) and the work spindle (10);
- wherein the work holding fixture (29) is joined to, and suspended downwards from, the z skid (23),wherein the z skid (23) is mounted on a second frame (17) for displacement on z guides (24), the second frame (17) being disposed above the working area (14);
- wherein the second frame (17), the first frame (2), the machine bed (1) and props (21), which connect the second frame (17) with the machine bed (1) on a side that faces away from the work spindle (10), form an inherently rigid machine frame (22) that defines the working area (14);
- wherein the work spindle (10) is disposed on a compound slide rest formed by a y skid (7) and an x skid (4) which are part of the work spindle motion unit (13);
- wherein the work spindle (10) is non-displaceable in the z direction;
- wherein a chip removal arrangement (35) is provided underneath the work holding fixture (29) and the work spindle (10);
- and
- wherein the z skid (23) is drivable in the z direction by at least one z linear motor (25).

A triaxial machining tool comprising:
- a working area defined by
- a bottom machine bed;
- a vertical first frame including a vertical compound slide motion unit with a first skid and a second skid attached to said machine bed;
- a work spindle attached to said compound slide motion unit before said working area, said work spindle movable in a plane defined by a vertical and horizontal direction;
- a z tool attached to said work spindle, a rotational axis of the work spindle and said z tool extending in a z direction perpendicular to said plane, before said working area;
- an above second frame attached to said first frame and including a z skid movable in the z direction and disposed above said working area;
- at least one of a workpiece holding unit and a fitting unit, suspended from said z skid;
- a chip removal arrangement underneath said work spindle;
- and wherein the second frame, the first frame, the machine bed, and props, which connect the second frame with the machine bed on a side that faces away from the work spindle, form an inherently rigid machine frame that defines the working area.
