A machine tool has at least 5. A tool holder assembly permits a tool holder spindle to be displaced relative to the frame along a first axis of translation and along a second axis of translation perpendicular to the first axis of translation and implementing slides in a plane forming an angle of between +40° and +50° relative to the first axis of translation. A part holder assembly permits a part to be displaced along a third axis of translation perpendicular to the other axes of translation, about a first axis of rotation parallel to the third axis of translation and about a second axis of rotation perpendicular to the first axis of rotation. The length of the precision path connecting the part to the tool via the frame and the assemblies of the machine is less than 1600 mm.

The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

Provided is a turning and milling system, comprising: a work platform comprising a first drive mechanism; a rotating platform, said first drive driving said rotating platform to rotate on the said work platform and drive a workpiece to rotate about a vertical axis; a blade assembly comprising a blade and a second drive mechanism connected to the blade; said second drive mechanism drives the blade to move in the horizontal direction, changing the machining radius of the blade.

A machine tool includes a base, a table, a main spindle, and a trunnion unit. The table is installed on the base. A tool is mounted to the main spindle. The main spindle is caused to approach a workpiece on the table along an up-down direction. The trunnion unit is configured to rotatably hold the table on which the workpiece is placed using a rotation axis along a front-rear direction as a center. The trunnion unit is disposed movable in a right-left direction.

Machine tool including a workpiece carrier assembly including a workpiece carrier for supporting a plurality of workpieces, the workpiece carrier assembly being supported on a workpiece carrier support for horizontal movement in a first direction parallel with a horizontal Z axis, a tool carrier configured for carrying a plurality of tools corresponding to the plurality of workpieces and for machining the workpieces, the tool carrier being supported on a tool carrier support for horizontal movement in a second direction parallel to a horizontal X axis, the X axis being perpendicular to the horizontal Z axis, where the tool carrier is displaceable on the tool carrier support in the second direction between an operative position in which the tools are arranged for the contacting the workpieces and an inoperative position in which the workpieces are not contactable by the tools, where the workpiece carrier is arranged to be rotatable around an axis parallel with the X axis, and where the workpiece carrier includes a workpiece support area for supporting the workpieces and arranged substantially in parallel with the X axis.
