In a working machine, left and right side walls are erected on a bed, a forward/backward saddle is movable in forward/backward directions, left and right sides of the forward/backward saddle are movably supported with the left and right side walls, a forward/backward drive device is arranged on the left and right side walls, to move the forward/backward saddle in the forward/backward directions, a left/right saddle is arranged on the forward/backward saddle and movable in left/right directions, a left/right drive device is arranged on the forward/backward saddle on each of forward/backward sides of the left/right saddle, to move the left/right saddle in the left/right directions, an up/down slider is movable up and down and arranged on the left/right saddle, a lower portion of the up/down slider is provided with a processing head to which a processing tool for processing a work set on the bed is removably and replaceably attached.

A machine tool includes a rotation table unit including a rotation table configured to rotate with respect to a first axis. The rotation table unit is configured to move along a second axis that is orthogonal to the first axis. The machine tool includes a spindle unit including a spindle configured to rotate with respect to a third axis that is orthogonal to the first axis and the second axis. The spindle unit is configured to move along the third axis. The machine tool includes a bed that supports the rotation table unit and the spindle unit. A front part of an upper surface of the bed includes a recess in which the rotation table unit is arranged. The spindle unit is located at a rear part of the upper surface of the bed.

An apparatus for machining a workpiece has a housing having a vertical front wall and first and second side walls extending generally perpendicularly back from outer edges of the front wall, directed horizontally oppositely away from each other, and defining first and second planes themselves delimiting a space. First and second vertical guides on the first and second side walls outside the housing carry first and second vertical slides moveable vertically on the first and second vertical guides of the first and second side walls. First and second horizontal guides on the first and second vertical slides carry first and second horizontal slides movable horizontally on the first and second horizontal guides of the first and second vertical slides between the first and second front work stations and the first and second rear transfer stations.

The machine tool comprises a fixed bearing structure, a movable bearing structure supported by the fixed bearing structure and displaceable with respect thereto along a horizontal direction, a tool-carrying carriage mounted vertically translatable in the movable bearing structure between an upper end position and a lower end position, situated at respective heights or levels separated by a predetermined vertical distance, and a motor adapted to cause a horizontal displacement of the movable bearing structure with respect to the fixed bearing structure and/or a vertical displacement of the tool-carrying carriage with respect to the movable bearing structure. The fixed bearing structure is configured such that the movable bearing structure is supported and driven in its displacement at a height or level intermediate between the heights or levels of the end positions of the tool-carrying carriage.

A machine tool comprises a frame, which carries a fixed gantry for supporting at least one tool spindle. The gantry comprises a gantry recess, through which a working space is accessible. The one or more tool spindles on the gantry can each be moved vertically in a first direction and in a second direction orthogonal to the first direction. The machine tool further comprises a workpiece table with at least one location for supporting workpieces. The workpiece table is movable in translation in a third direction Y orthogonal to the first direction and the second direction. At least one tool magazine is associated with the at least one tool spindle tool spindle. Tools for tool changing can be fed through at least one magazine opening in the gantry. Tool changing between the one or more tool spindles and the at least one tool magazine takes place in a pick-up process.

A machine tool which causes a tool mounted on a main spindle and workpiece attached to a table to move relative to each other so as to machine the workpiece, said machine tool being equipped with: a column that has guides for guiding movements in the vertical direction, that is, the direction of gravity; and a moving body that supports a spindle head at the front and moves in the vertical direction along the guides. The guides comprise a pair of right and left first guides and at least one second guide that is provided on the inner side of and posterior to the pair of first guides.

The present invention relates to a machine tool for machining a workpiece. The machine tool has a motor spindle for the rotative actuation of a tool. The motor spindle is supported by a stand. A turning bearing is provided at the stand and the motor spindle at the turning bearing is pivotable and positionable about a first turning axis. At the motor spindle, a linear guide is provided, which enables an advancing movement of the tool parallel to the spindle axis.

A grinding machine for grinding of a profile, comprising a machine bed, wherein a machining device is arranged on the machine bed, wherein the machining device comprises a swivel head which carries a first grinding spindle with a first grinding tool, especially with a roughing grinding tool, and a second grinding spindle with a second grinding tool, especially with a finishing grinding tool, wherein a workpiece carrier being a rotary table is arranged on the machine bed. To allow the production of workpieces with a complex geometry in a high precision in an economical manner the invention proposes that the swivel head further carries at least one third grinding spindle with a third grinding tool, wherein the swivel axle of the swivel head is directed horizontally and the axis of rotation of the rotary table is directed vertically.
