Abstract: An operating method of a numerical-control machine tool characterized in that it comprises the steps of providing the tool-carrying head of the numerical-control machine tool with a detection device adapted to measure the values of the tilting of the detection device relative to a predetermined reference inertial plane; and moving the tool-carrying head in space so as to place said detection device in succession in a multitude of control points distributed on a first detection plane, and create at least a first digital map that contains the tilting values of the detection device relative to the reference inertial plane, in each of said control points.

Abstract: A numerical-control machine tool is provided that includes a tool-holder head which is provided with a tool-holder spindle and is capable of rotating/tilting the tool-holder spindle about two different rotation axes inclined to one another; a movable supporting structure that supports the tool-holder head; inclinometer microsensor(s) that are located on the movable supporting structure of the machine to measure/determine the tilt of the element on which the sensors are mounted; and an electronic control device that commands the moving members of the movable supporting structure and of the tool-holder head. The electronic control device is electronically connected to the inclinometer microsensor(s) controls the moving members of the movable supporting structure and of the tool-holder head based on signals arriving from the inclinometer microsensor(s), so as to correct the spatial position and/or the orientation of the tool-holder spindle.

Abstract: A linear encoder for numeric-control machine tools is provided that includes: a substantially rectilinear section-bar, which is adapted to be fixed on the structure of the machine tool; a substantially rectilinear scale strip, which is fixed on the section-bar so as to extend along the section-bar parallel to the section-bar longitudinal axis; a movable slider which is fitted/mounted on the section-bar so as to be able to move along the section-bar parallel to the section-bar longitudinal axis and skimming the scale strip, and which is adapted to be rigidly fixed to the movable piece of the machine tool; an electronic reading apparatus which is at least partially placed aboard the movable slider and is adapted to read the position of the movable slider on the scale strip; and a thermal-stabilization device which is adapted to bring and maintain substantially the whole scale strip stably at a predetermined target temperature.

Abstract: 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.

Abstract: A numeric control machine tool of the type comprising: a basement; a substantially rectilinear main supporting crossmember which extends above the basement and has two axial ends structured so as to rest stably and in an axially sliding manner on two reciprocally parallel rectilinear guides present on the basement; a movable slide which is fixed protruding onto a side of the main supporting crossmember, with the possibility of moving along the body of the main supporting crossmember; a substantially rectilinear vertical movable tower, which is fixed on the movable slide in a substantially vertical position and with the possibility of translating with respect to the movable slide in a vertical direction; and a tool-hold head which is fixed on the lower end of said vertical movable tower; the main supporting crossmember being structured so as stably to support the weight of the movable slide, the vertical movable tower and the tool-holder head, and the numeric control machine tool also comprising a substantiall

Abstract: In a conditioning system for a manufacturing machine, in particular a machine tool, a machine tool framework is arranged inside a sealed casing. Ducts are arranged at machine tool regions to be thermally conditioned. The ducts comprise air flow outlets and are coupled to a conditioned air delivery manifold supplied by a conditioning device. Solenoid valves are provided at the outlets to control air flow.
