A beam of a gantry-type stage structure includes an accommodating space defined by a lower plate, an upper plate, a front plate, a rear plate and two lateral plates. A truss unit is disposed in the accommodating space, and includes lower and upper joint members which are respectively disposed on the lower and upper plates, first and second vertical members which extend uprightly from the lower and upper joint members, respectively, and diagonal members each of which extends to interconnect one lower joint member and an adjacent upper joint member to provide the beam with a great structural strength and a lightweight structure.

The present invention relates to a modular frame for CNC machining, comprising: a first side panel and a second side panel, each side panel for with an elongated base with a notch at either end and a vertical extension from the base with a notch at the distal end of the vertical extension; a first crossbeam and a second crossbeam, each crossbeam having a notch at either end, the notches on the crossbeam oriented in an opposing direction to the notches on the side panels; and a gantry beam, the gantry beam having a notch at either end, the notches on the gantry beam oriented in an opposing direction to the notches on the side panels, wherein the side panels, crossbeams and gantry beam are user-assembled into the modular frame via alignment and engagement of the respective notches on the crossbeams and gantry beam with the notches on the side panels, and wherein user assembly of the modular frame is performed without the use of tools.

A numerical-control machine tool is provided and includes a load-bearing beam which extends horizontally, has two axial ends resting in sliding manner on two lateral shoulders that rise from a basement and extend horizontally side by side so as to define a longitudinal corridor orthogonal to the longitudinal axis of the beam; a spindle-holding carriage which is movable on the load-bearing beam parallel to the longitudinal axis of the beam; a spindle-holding shaft which is fixed to the spindle-holding carriage in a vertical position, and is movable on the spindle-holding carriage parallel to its longitudinal axis; a front wall and a rear wall that close the two ends of the longitudinal corridor; an upper cover which closes the longitudinal corridor at the top; and an ambient conditioning unit which is adapted to bring and maintain the temperature of the air present inside the machining chamber around a given target value.

An all-directional profiling machine has a foundation. A profiling device is disposed on the foundation. The profiling device swings leftward and rightward at the same height relative to the foundation. An upright post is disposed at one end of the profiling device and has a terminal portion extending upward. A workbench is pivotally connected to the terminal portion of the upright post. The workbench tilts vertically and swings horizontally relative to the upright post. Therefore, the all-directional profiling machine performs a multi-angle profiling cutting process without demounting a workpiece repeatedly such that the processing of oblique surfaces is quicker, simpler and more precise, so as to not only meet various requirements of different processing angles but also feature enhanced processing efficiency.

A levelling machine includes a pair of spaced apart rail assemblies, a gantry assembly and a face mill assembly. The spaced apart rail assemblies define an x axis. The gantry assembly is moveably attached to the pair of spaced apart rail assemblies whereby the gantry assembly defines a y axis. The gantry assembly is moveable in the x axis along the pair of spaced apart rail assemblies. The face mill assembly is moveably attached to the gantry assembly and is moveable in the y axis along the gantry assembly. The face mill assembly has a plurality of saw blades, the saw blades being generally in an x-y plane defined by the x axis and y axis. The saw blades have a plurality of teeth that extend downwardly generally in a z axis. The face mill assembly is moveable in the z axis.

The present disclosure relates to an apparatus for cooling a ram spindle and compensating for a load and a machine tool including the same, in which a cooling unit cools a friction part between a ram spindle and a saddle when the ram spindle, which is transferred by means of the box guideway, is thermally deformed, and a hydraulic pressure closed circuit automatically compensates for a load applied to a plurality of gibs, which is provided inside the saddle and installed between the saddle and the ram spindle, except for a reference surface with which the ram spindle is in close contact, so as to correspond to the reference surface in a horizontal direction or a vertical direction in case that a load applied to the gib is changed by thermal deformation of the ram spindle even though the cooling unit is used, such that the surface pressure applied to the gib is automatically and constantly maintained, which makes it possible to improve machining precision of the machine tool, reduce machining costs by preventing a waste of resources, improve productivity by increasing a non-machining time, and improve stability and reliability of the machine tool.

A system (40) is provided for processing a workpiece (44). The system (40) includes a support surface (48) for supporting the workpiece (44) and defining a processing path (P) along which the workpiece (44) may travel relative to the system (40). The system (40) includes at least one tool (64a, 64b, 64c) for performing a process on the workpiece (44) that is movable in a work zone (WZ) along a predetermined length (L) of the workpiece (44) in a direction along the processing path (P). The system (40) includes a movable clamp assembly (80) having opposing clamping pads (84, 88) movable into and out of the work zone (WZ) along the processing path (P) to clamp a portion of the workpiece (44) located in the work zone (WZ) prior to the at least one tool (64a, 64b, 64c) performing a process on the workpiece (44).

To provide a portal-shaped tear processing device which is capable of stably performing high precision tear processing.

Provided is a portal-shaped tear processing device including: a portal-shaped frame; a rail member; a controlled movement robot; and a tear processing means, in which the column member and the beam member have an outer shell portion, a filling member enclosed in the outer shell portion, and a hollow portion boring the filling portion along a major axis direction of the column member and the beam member.

In a machine tool, in particular a laser machine tool, a workpiece slide or tool slide is movable along a guide rail and has at least two guide carriages that are guided on the guide rail. The machine tool has a covering hood that is moved along with the slide, for covering that rail section of the guide rail that is located between the two guide carriages. The covering hood is a part that is not connected to the slide. The covering hood is guided on the guide rail in a displaceable manner between the two guide carriages and is entrained in the displacement direction by the rear guide carriage when the slide is displaced.
