A machining accuracy diagnosing device includes a temperature regulation operating pattern setting unit, a cutting condition setting unit, a temperature information acquiring unit, and a machining accuracy influence amount predicting unit. The temperature regulation operating pattern setting unit sets an operating pattern of a temperature regulating unit. The cutting condition setting unit sets a scheduled machining start time and a scheduled machining end time. The temperature information acquiring unit acquires an influencing temperature of the temperature regulating unit on the machine body temperature and/or an air temperature outside the plant. The machining accuracy influence amount predicting unit predicts an influence amount of the temperature regulating unit on the machining accuracy based on the operating pattern, the scheduled machining start time and the scheduled machining end time, and at least one of the influencing temperature and/or the air temperature outside the plant and a set temperature of the temperature regulating unit.

A machining accuracy diagnosing device includes a diagnosing information acquiring, an opening time setting unit, a cutting time setting unit, and a machining accuracy influence amount predicting unit. The diagnosing information acquiring unit acquires at least one of a room temperature inside the plant, a set temperature of a temperature regulating device, an air temperature outside the plant, a wind speed outside the plant, an opening degree of the door or the shutter, and a machine body temperature. The opening time setting unit sets an opening time of the door or the shutter. The machining accuracy influence amount predicting unit predicts an influence amount of opening of the door or the shutter on the machining accuracy based on the acquired information for diagnosis, the set opening time of the door or the shutter, and a set scheduled machining start time and a set scheduled machining end time.

Provided is a machine tool (1) which is capable of measuring machining accuracy of a workpiece (W) with high accuracy and enables the time required from machining to measurement of machining accuracy to be greatly reduced. The machine tool (1) machining a workpiece (W) while moving a tool and the workpiece (W) relative to each other includes a cover (2) separating from outside a machining area for machining the workpiece (W) therein, and temperature adjusting means (30) used in machining of the workpiece (W) to adjust an ambient temperature of the machining area.

A machine tool comprises a structure in which at least one component (12) of this structure is thermally insulated from the external environment and in which this component (12) is sealed so as to prevent fluid communication between the inside (18) and the outside of the component (12) of the structure.

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 temperature control system for a machine tool is equipped with a first temperature control device configured to control the temperature of gas supplied to a gas bearing, a second temperature control device configured to control the temperature of a room interior and to issue a notification of its own operation state to the outside, a gas supply section configured to supply gas whose temperature has been controlled by the first temperature control device, and a gas supply control section configured to perform the gas supply control of the gas supply section so that gas is distributed to both of the gas bearing and an interior space, when receiving the notification that the operation state of the second temperature control device is abnormal.

A machining system capable of preventing mist from leaking out from an enclosure to the outside. The machining system includes a first enclosure including an opening and configured to define a first space in which a workpiece is processed, a second enclosure arranged adjacent to the first enclosure and configured to define a second space communicating with the first space through the opening, wherein a robot which can advance to and retreat from the first space through the opening is installed in the second space, and a pressure adjustment device configured to increase a pressure in the second space higher than a pressure in the first space.

Disclosed herein is a cyclonic system for performing subtractive machining in microgravity systems. The cyclonic system comprises: an enclosure, a blower, and a debris collection module to collect the debris from the milling machine. The enclosure includes a top plate, a base plate, and a tapered side wall joining the top plate to the base plate. The enclosure defines a chamber to house a milling machine having a cutter tool. The blower generates an airstream that induces a cyclonic airflow to achieve cyclonic separation of debris within the enclosure. In operation, the cyclonic airflow urges the debris from the milling machine toward the base plate and into the milling machine.
