A device for positioning a module of modular bed (4) for machine tools with respect to a reference module (41), comprising a liquid-based leveling device (2) which allows an alignment of the modules (41, 42) according to three degrees of freedom (Z,a,b) and a base support (3) which allows a spatial movement of the module to be installed (42) at least according to the three degrees of freedom (Z,a,b).

A workpiece orientation mechanism includes: a driving device including a transmission motor and a controller which are connected with each other via signal, the transmission motor defining an axial direction; a rotating seat, combined with the transmission motor, and capable of being driven to rotate by the transmission motor; an orientation head disposed to the rotating seat to rotate synchronously with the rotating seat, wherein the orientation head is capable of moving along the axial direction relative to the rotating seat, one end of the orientation head includes a mounting head, and an inductor is disposed to the orientation head; a reset means, arranged between the rotating seat and the orientation head, and positioning the orientation head at a predetermined position; and a sensor facing the inductor, wherein the sensor is signally connected with the controller.

A leveling adjustment device attached to a machine tool with supporting foot portions being adjusted manually to change a height, which includes a sensing module and a microcontroller unit. The sensing module senses the machine tool for inclined extents in two directions perpendicular to each other and then generates a sensed data. The microcontroller unit receives the sensed data and provides a graphical operation interface with first blanks and second blanks. The first blanks are used to fill with a length and width data of the machine tool while the second blanks are used to fill with a coordinate data corresponding to each of the supporting foot portions. The microcontroller unit calculates an adjustment sequence and an adjustment value corresponding to each of the supporting foot portions based on the data in the first and second blanks in conjunction with the sensed data and then displays in the graphical operation interface.

A workpiece rotating apparatus including a first rotary positioner and a second rotary positioner which are arranged to face each other in a direction along a substantially horizontal rotation axis, which hold, respectively, one end portion and the other end portion of a long workpiece, and which can rotate the workpiece around the rotation axis, a linear motor which linearly moves the second rotary positioner in a direction along the rotation axis, and a motor controller which controls the linear motor to adjust a position of the second rotary positioner in a direction along the rotation axis, and the motor controller controls the linear motor so that magnitude of force acting on the linear motor from the other end portion of the workpiece via the second rotary positioner becomes equal to or smaller than a predetermined threshold.

A tool includes a handle, an extension member extending from the handle, and an anchor assembly coupled to the extension member opposite the handle. The anchor assembly is configured for selective anchoring to a seat track of an air cargo pallet, and the anchor assembly includes at least one locking member that is movable between an unlocked position and a locked position. In particular, when the at least one locking member is in the unlocked position, the at least one locking member is configured to advance into a slot of the seat track. When the at least one tool is in the locked position, the at least one locking member is configured to mechanically interfere with at least a portion of the seat track in a manner retaining the at least one locking member in the slot, thereby anchoring the anchor assembly to the seat track.

The invention relates to a downdraft table (1) having a workpiece holder (2) for a workpiece to be held, wherein the workpiece holder (2) is configured in a stationary manner, wherein a suction-extraction device (3) is arranged beneath and/or next to the workpiece holder (2), said suction-extraction device (3) being used to discharge particles and/or gases downward in a waste air flow, wherein the suction-extraction device (3) is arranged around the workpiece holder (2) with respect to the latter and is configured to be rotatable about the workpiece holder (2).

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.

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.
