Machine tool and a base for a machine tool comprising a machine bed to support a first work module having a first end effector held thereon, and a second work module having a second end effector held thereon on a base surface in an area between two mutually opposed sides which delimit the machine bed, the sides extending between an underside of the machine bed and an upper side of the machine bed, when viewed in the vertical direction; a first bearing element which is fixed relative to the machine bed for holding the first work module; and a second bearing element which is fixed relative to the machine bed for holding the second work module; wherein the first bearing element and the second bearing element are arranged one above the other, when viewed in the vertical direction.

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.

In the internal milling machine according to the invention for milling a work piece that rotates during machining with an annular internal milling cutter (5) on the one hand side the Z slide (4a, b) of each tool support (3a, b) includes a pass through opening and on the other hand side the transversal slide (7) supporting the internal milling cutter (5) is move able in the X-direction, the running direction of the mounting surface (1a) of the bed (1) wherein the mounting surface slopes downward in a forward direction. Based on this general configuration and in particular the arrangement of the Z-slides (6a, b) for the at least one tool support (3a, b) outside of the Z-supports (16a, b) for the opposite spindle stock (2′) yields advantageous centers of gravity in particular of the move able components and a high level of stability of the machine and therefore high level of machining precision of the machine.

A processing device of the invention includes a partition member partitioning a processing space and an external space, a frame body on which the partition member is mounted, a positioning unit for holding a workpiece at a predetermined position in the processing space, a processing unit for applying a predetermined process using a processing tool on the workpiece, an opening/closing member capable of opening/closing a first opening formed in the partition member, and an instrument attachment member to which a control instrument is attached, wherein the partition member has a plurality of uniform mounting sections on which the opening/closing member and the instrument attachment member are mutually selectively mounted.

A mobile machine tool includes a main body, a machine bed head, and an end effector. The main body permits the machine tool to stand on the ground. The machine bed head is cantilevered relative to the main body. The end effector is guided on the machine bed head by a positioning system. The machine bed head is attached to the main body by a mechanically overdetermined frame.

Cement or other liquid-like material fills the hollow tubes of a machine tool under construction. The machine tool structures are held rigidly against a fixture while the substance dries. The machine tool so constructed is relatively lightweight and rigid, and obviates the need for precision machining of large portions of the apparatus.

The invention is a modular table-top automation apparatus, or for short, a tac, a word derived from an acronym for a table-top automation center, of which, this is the first. Employing integrated mechanical and electronic systems, a tac is a flexible, programmable apparatus, readily reconfigurable, which can be used as either a stand-alone unit, or as a cell within a configuration of other tacs or machines. The tac can utilize various purchasable application devices, mounted on one or two horizontal carriage rail assemblies, which extend past both sides of a frame containing a central work area, giving it a unique ability to load, position, perform numerous operations and unload a wide variety of small parts or assemblies. By combining with optional rotary magazines positioned on both sides of the frame, the tac can be set-up as a fully automatic “load and walk-away” production center.

A machining center configured for machining workpieces includes at least one column, a beam, at least one slider, a first driving member, a second driving member, a first main shaft and a second main shaft. The column can be configured for supporting the beam. The slider can be disposed on the beam and slidable along a length direction of the beam. Both the first main shaft and the second main shaft can be arranged on the slider and located on two opposite sides of the beam. The first driving member can be configured for driving the slider to slide relative to the beam. The second driving member can be configured for driving the first main shaft and the second main shaft to operate. The first main shaft and the second main shaft can be configured for synchronously or asynchronously machining the workpieces.

The invention discloses a system for hole making for an aircraft skin by normal positioning and locking. The hole-making system includes a posture adjustment part, a normal positioning and locking part and a hole-making execution part. This system solves the problems that the device in the prior art has high complexity and cumbersome positioning and does not adapt to complex curved surfaces, thereby failing to satisfy the needs of efficient hole making in different space states. In the present invention, the expansion of an outer expansion sleeve in a bottom sleeve locks a normal direction for hole making, thereby ensuring the positioning accuracy of the normal direction. An axial position is locked by the mutual cooperation of an axial positioning groove of the bottom sleeve and an axial positioning rib of the outer expansion sleeve. A hole-making auxiliary cylinder contracts to counteract part of an axial force for hole making.

A reconfigurable machining center includes a base structure extending in a first direction, a movable crossmember movable in the first direction and provided with a machining head, supporting elements on the base structure to enable movement of the movable crossmember along the first direction, a first leadscrew rack, integral with the base structure and having a first helical circular toothed sector, and extending along the entire base structure parallel to the first direction, and a first screw rotatably coupled to the movable crossmember and engaging a corresponding first leadscrew rack, and having a rotation axis parallel to the first direction. The longitudinal extension of the base structure in the first direction is an integer multiple of the pitch of tooth of the leadscrew racks, and the base structure includes coupling elements adapted to couple the base structure to a following and/or preceding adjacent base structure along the first direction.
