A workpiece fixing device for fixing a workpiece by vacuum for machining thereof includes a support device on which the workpiece can be laid for fixing, and at least one vacuum chamber which is formed starting from the support device. The workpiece fixing device has a first fixing region and a second fixing region different from the first fixing region. The support device has a first support channel profile in the first fixing region and a second support channel profile different from the first support channel profile in the second fixing region.

A collision-proof spring transfer takes place in the process, which comprises a continuous transfer of coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and an automatic prevention of any re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.

An NC lathe including a first spindle, a second spindle capable of holding a cut-off workpiece delivered from the first spindle, a second tool post on which a plurality of tools are attachable to machine the workpiece held by the second spindle, a product receiver provided on the second tool post, a Y2-axis motor capable of moving at least one of the second tool post and the second spindle in a Y2-axis direction, and an X2-axis motor capable of moving at least one of the second tool post and the second spindle in an X2-axis direction. The second tool post has a plurality of tool mounting parts where the tools are attachable. The tool mounting parts are aligned at intervals in the Y2-axis direction. At least one of the tool mounting parts is arranged in a position overlapping the product receiver with respect to the X2-axis direction.

The invention relates to a machining device for workpieces, comprising a first workpiece table that is displaceable along a longitudinal direction and comprising a second workpiece table that is displaceable in the longitudinal direction, wherein the two workpiece tables are arranged spaced apart perpendicular to the longitudinal direction, wherein each of the two workpiece tables comprises clamping elements for clamping a workpiece, and wherein a guide element is also provided, which is arranged aligned perpendicular to the longitudinal direction and is used for the displaceable guidance of a tool element, comprising a first tool element, which is displaceably arranged on the guide element for machining the workpiece, comprising a first manipulator device for gripping and positioning a workpiece into at least one clamping element of one of the workpiece tables or for removing a workpiece from at least one clamping element of one of the workpiece tables.

A three-dimensional printer with improved adjustment mechanisms for calibrating the orientation of the build platform and an extrusion assembly to optimize the accuracy of models deposited on the build platform. The printer includes a frame carrying an extrusion assembly proximate the top, and a carriage within. A build platform is mounted on the top of the carriage. Carriage adjustment mechanisms are provided at at least two corners of the carriage for calibrating the orientation of the build platform with respect to the X-Y plane. An extrusion assembly adjustment mechanism is provided at at least one end of the extrusion mechanism for calibrating the orientation of the extrusion mechanism with respect to the Y-axis. A height adjustment mechanism is provided for translating the carriage within the frame along the Z-axis.

A manufacturing system including a base and multiple work machine modules that are arranged in an arrangement direction on base to be attachable to and detachable from base, in which one wheel of a pair provided on work machine module is engaged with one rail of a pair provided on base in a state in which positional deviation in the arrangement direction is prohibited, and the other wheel of the pair is engaged with the other rail of the pair in a state in which positional deviation is permitted in the arrangement direction, thereby the position of work machine modules on the base in the arrangement direction is specified, and work machine modules are fixed at a setting position on the base to be restricted so as to be drawn toward the base by a module fixing mechanism that is provided on the base.

A machine tool capable of reducing entry of a workpiece chip into a product discharge chute. A controller controls a receipt of a product made of a workpiece held by a first spindle by a product receiver in a product receiving position, movement of the product receiver to a product dropping position and rotation of the product receiver to drop the product to the product discharge chute through an opening of the product discharge chute, and movement of the product receiver to the product receiving position to receive the product again. A second spindle is kept on standby in the product dropping position during which the opening of the product discharge chute is closed by the product receiver.
