The present disclosure involves occasions where precise two-dimensional motion takes place, and is applicable to XY motion stages for precise displacement compensation. The present disclosure particularly involves a stiffness-frequency adjustable XY micromotion stage based on stress stiffening, which includes X-direction and Y-direction motion sub-stages and corresponding drivers and a micromotion working table. The micromotion stage uses membrane sets that have tension levels thereof adjusted by bolts as a flexible hinge, so as to achieve independent adjustment of the vibration frequency of the XY micromotion stage. The present disclosure implements the foregoing configuration based on prestressed membrane, so the frequency is adjustable. The inherent frequency of the micromotion stage can be adjusted before or during operation according to various working conditions and driving frequency. The two feed motion direction are perpendicular so as to prevent the micromotion working table from coupling during two-dimensional motion.

A cross-coupling control method for moving beam of gantry machine tool is disclosed, which relates to the technical field of CNC machine tool control. The cross-coupling control method includes: Step 1: establishing a crossbeam dynamics model considering a ram on the crossbeam, and at the same time simplifying the model for an observer design; step 2: realizing a PID control parameter adjustment of motors at both ends in accordance with a method of parameter tuning of a unilateral servo control system; using a servo system with the same control parameters to jointly drive the crossbeam up and down, realizing the synchronous control and realizing PID control parameter tuning for both end motors. The disclosure not only reduces the synchronization error caused by the torsion of the crossbeam, but also solves the synchronization error caused by the asymmetric load on both sides, and improves the system robustness and stability.

The invention relates to an interchangeable milling adapter (20) for a work table (60), which comprises a receptacle (21) for a milling machine (70) and an angular adjustment (22).

Furthermore, a work table, a milling unit and their use for adjusting a milling machine are described.

A workpiece carriage for workpiece transport includes a guide unit oriented in a longitudinal direction, a drive unit having an electrical supply and a drive motor, and a workpiece gripping unit having two clamping jaws movable relative to one another. A machine tool includes at least one workpiece table, with at least one tool unit movable relative to the workpiece table and with at least two workpiece carriages that are displaceable individually in the longitudinal direction along a machine bed of the machine tool. A manufacturing cell includes such a machine tool and a workpiece supply. The two clamping jaws of the workpiece gripping unit can be displaced relative to one another in a height direction oriented normal to the longitudinal direction and normal to a transverse direction oriented normal to the longitudinal direction. This expands the possible applications of the workpiece carriage.

A machining tool positioning system includes a post configured to rotatably mount relative to a hollow component to be machined. A base member slidingly mounts relative to the post.

A second actuator is coupled at a first end to the base member and coupled at a second end to the machining tool slide mount is configured to selectively move the machining tool slide mount along the rail. A motor may optionally turn the post to rotate the position of the base member and machining tool.

A machine tool includes a tool assembly having a tool carrier support and a tool magazine. The tool assembly is displaceable in parallel with an X axis. The tool carrier support supports a tool carrier for driving a tool.

The tool magazine of the tool assembly is configured for supporting a number of tools. The tool magazine is attached to the tool carrier support for movement with the tool carrier support in parallel with the X axis.

The tool assembly includes a drive component configured for displacing the tool magazine in relation to the tool carrier support, between a first position in which the tool magazine is not facing the tool carrier, and a second position in which the tool magazine is facing the tool carrier, for allowing tool replacement.

A moving platform includes two sliding seats, two sliding blocks, a carrying member, and two weight blocks. The two sliding seats extend along a first axis and are arranged in a second axis. The two sliding blocks are respectively slidably disposed at two inner sides of the two sliding seats to move along the first axis. The carrying member is connected between the two sliding blocks. The two weight blocks are slidably disposed at two outer sides of the two sliding seats to move along the first axis. The two sliding blocks and the two weight blocks are configured to move in opposite directions along the first axis.
