An operation method is described for a numerical control tooling machine comprising a piece-carrying table rotatable about a—in use—vertical axis and N machining stations, N≥2, arranged around the table, with the steps of rotating the table to bring a piece in front of a station, disconnecting the piece from the table, transferring the piece from the table to the station, fixing the piece to the station, processing the piece at the station, disconnecting the piece from the station, transferring the piece from the station to the table, fixing the piece to the table, rotating the table to bring the piece in front of a different station or unloading the piece from the table.

The invention discloses a double-station gantry combined machining system allowing automatic overturning of workpieces, which comprises a first mobile gantry machining unit, a second mobile gantry machining unit, an overturning platform, a first workpiece fixing table, a second workpiece fixing table and a guide rail, wherein the overturning platform is positioned between the first gantry machining unit and the second gantry machining unit. According to the invention, the system is highly integrated, continuous machining of a gantry machine tool is completed, the working efficiency is improved, and the machining cost of the system is reduced.

A machining center equipped with a device for mounting on a clamp parts to be worked or which have been worked, such as profiles, which has a supporting frame for supporting a turntable with two or more stepped positions or placements or workstations, an loading basket and an unloading basket.

The machining center comprises a robot configured to remove or to associate, with each one of said two or more stepped positions or placements or workstations, the parts or the profiles to be worked and which have been worked at a plurality of fixed RPS or reference points and mobile mechanical components, according to a single positioning that is adapted to allow access by machining devices to any zone in the space of the profiles to be worked by modifying only the condition that the two or more stepped positions or placements or workstations are in.

The present disclosure provides a spindle structure including a base, a spindle, a sliding member, a restoring mechanism, and a restriction member. The spindle is rotatably received in the base and forms a receiving room. An end of the receiving room is a blind end communicating exterior via a gas channel. The sliding member is slidably received in the receiving room, and two ends thereof are a piston and a driving portion respectively. A gas cavity is defined between the piston and the blind end. The sliding member tends to move toward the blind end due to the restoring mechanism. The restriction member is connected to the driving portion and radially deforms when the sliding member slides so as to fix or to release the tool-holder. The sliding member slides outward when the gas cavity is injected with gas via the gas channel.

A multi-axis machining center for processing multiple parts independently includes a base frame, a processing table provided on the top of the base frame to fix a workpiece, a vertical support provided vertically on one side of the base frame, a processing part provided on the vertical support to process the workpiece, and a tool changer configured to automatically change a plurality of tools. The processing table is divided into a first table and a second table which are driven independently of each other. The processing part includes a first processing part and a second processing part provided in front of the vertical support and driven independently of each other. A first tool changer is provided on one side of the first table. A second tool changer is provided on one side of the second table.

A machine tool is provided with two vertically oriented tool spindles that are arranged to hold tools and that are movable vertically in a first direction and horizontally in a second direction orthogonal to the first direction. Furthermore, the machine tool is provided with two workpiece support devices for clamping workpieces in place. At least one of the two workpiece support devices is movable horizontally in a third direction orthogonal to the first and the second direction. The two tool spindles and the two workpiece support devices are mounted on a common machine frame with a common working space, wherein the two tool spindles are movable parallel to one another in the second direction. The two tool spindles are facing one another.

A method for mounting on a clamp parts or profiles in a processing center provided with a supporting frame for a turntable, comprising a robot for the loading/unloading of the profiles to be worked and of the subsequently worked profiles.

The method provides for the steps of inserting the profile to be worked, by means of the robot, in a region arranged below at least one first open clamp; resting the profile to be worked on at least one first lower fixed reference, resting the profile to be worked on a second and/or third front fixed reference, resting the profile to be worked on at least one fourth lateral fixed reference, laterally closing the profile to be worked and then upper closing of the profile to be worked.

The present invention relates to a transport device (100) for receiving one or more module units having machine tool accessory devices and for transporting the one or more received module units to a machine tool (1000) set up on a base surface for use of the machine tool accessory devices of the one or more received module units on the machine tool (1000), wherein the transport device (100) is freely movable on the base surface for positioning the one or more received module units relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

A machine tool includes a plurality of modules, and a control means for controlling operation of the modules, wherein the plurality of modules include a fixed module and two movable modules. The control means includes a restriction means for restricting the movement of the two movable modules for allowing only one of the movable modules to be moved to a facing position facing the fixed module; and a determination means for determining the movable module to be moved to the facing position. The control means is configured to control the operation of the plurality of modules so that, when the operation under cooperation of the fixed module and one of the movable modules has been completed, the restriction means releases the restriction of the movement of the other movable module to the facing position.
