A portable rail system for mounting an engraving device includes rails and crossbar members that are precisely joined, and include height adjustment devices for incrementally adjusting the height of the rail system relative to a work surface or contact surface, thus making the portable rail system capable of being assembled and disassembled at a work site to enable the use of an engraving device, such as a CNC router engraving systems, in situ, or on-site, rather than in a workshop. The portable rail system enables the use of a CNC router device or other engraving device on vertical surfaces.

A machining center includes two independent carriages that are supported so that they can slide along respective longitudinal translation axes by a pair of parallel horizontal rails which are extended along a longitudinal direction and are fixed in a raised position to a supporting structure. Each one of the carriages supports a machining head which can move along a transverse translation axis and along a vertical translation axis by guiding components. Each of the machining heads supports a tool holding spindle so that it can rotate about a horizontal rotation axis by rotary support components. A workpiece holding table is supported at a base of the supporting structure so that it can rotate about a first rotation axis which is extended in a horizontal and longitudinal direction. Two mechanized tool magazines at the opposite longitudinal ends of the supporting structure are accessible by the spindles.

A water jets cutting machine includes a first rotating seat driven by a first motor to rotate about a first rotation axis, a second rotating seat driven by a second motor to rotate about a second axis, a water jets cutting head, an inertial measurement unit (IMU) for detecting an inclination angle of the water jets cutting head, and a controller connecting the first and second motors and the IMU. The controller is able to control the first and second motors to instantaneously conduct compensation for angular deviation of the water jets cutting head according to attitude and position signals which are fed back to the controller by the IMU.

A numerically controlled machine tool that can accurately control a position of a machining member for machining a workpiece. The numerically controlled machine tool comprises: a first post member installed on a main body slidingly in a left/right direction; and first, second and third horizontal rails installed on the main body lengthily in the left/right direction and respectively coupled to two points of the rear surface and one point of the front surface of the first post member for guiding sliding of the first post member.

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.

A gantry table includes a table main body. A gantry rail extends along the table main body, and a gantry rack extends along the table main body. The gantry table includes a gantry comprising a pinion gear that engages the gantry rack. The pinion gear drives the gantry to move along the table main body on the gantry rail. A tool bracket is movable along the gantry. The gantry table further includes a first adjustment bar and a second adjustment bar. The gantry rail and the gantry rack are attached to both of the first adjustment bar and the second adjustment bar. A joiner plate joins the first adjustment bar to the second adjustment bar. The gantry table includes a vertical adjustment that is configured to adjust a vertical position of the joiner plate with respect to the table main body. The gantry table further includes a depth adjustment configured to adjust a lateral position of the joiner plate with respect to the table main body.

A machine tool includes: a spindle head; a spindle rotatably supported on the spindle head; a chuck unit configured to chuck a tool inserted in an axis direction of the spindle; a tool holder configured to hold the tool attached to the chuck unit; and a rotary arm configured to move the tool holder to a reachable position of the spindle. The tool holder is supported on the rotary arm by a support mechanism, and the support mechanism includes a displacement following mechanism configured to support the tool holder on the rotary arm in a manner to be capable of displacing the tool holder in a direction intersecting an axis of the tool.

A machining center includes two independent carriages supported so that they can slide along respective longitudinal translation axes by two parallel horizontal rails fixed in a raised position to a supporting structure. The carriages support respective machining heads which can move along two respective translation axes. The machining heads support respective tool holding spindles in a rotatable manner about a horizontal rotation axis (Yr, Yr) by virtue of rotary support means. A workpiece holding table is supported at the base of the supporting structure. Two mechanized tool magazines are supported at the opposite longitudinal ends of the supporting structure and are accessible by the spindles. The rotary support and/or the workpiece holding table can rotate about a respective vertical axis.

This gantry type conveying device is provided with: a beam which is horizontally installed; a runner traveling along the beam; an elevator supported to be movable in the vertical direction with respect to the runner; and a loading part which is supported by the lower portion of the elevator and on which a workpiece is loaded. This processing line has the gantry type conveying device and a machine tool. The machine tool is provided with: a base; and a workpiece supporting device provided movable with respect to the base in a forward and backward direction perpendicular to the extending direction of the beam when viewed in a plane.

An autonomous production line for machining work pieces e.g. by sawing, milling, boring or grinding and proposes a roller conveyor with machining stations, a placement station and an unloading station. Machining robots machine the work pieces at the machining stations while the work pieces are supported on suction tables.
