A machining center is provided, which can complete replacement of processed works on stock shelves in a work storage section with unprocessed works within a time period significantly shorter than those in conventional techniques and improve the efficiency of an entire processing process.

In the machining center, a cover surrounding the work storage section includes an opening portion where rear surface regions of the stock shelves are exposed, a stock shelf access door that closes the opening portion and is driven to be opened and closed, a locking device for the stock shelf access door, a unlocking mechanism that is operable from the outer side of the cover to unlock the locking device, and a door opening/closing detection device that detects an opened or closed state of the stock shelf access door. A control unit of a CNC device includes an interlocking function of disabling the unlocking mechanism while an automatic pallet changer is driven, and a safety control function of prohibiting, based on a detection signal from the door opening/closing detection device, a drive unit of the automatic pallet changer from being driven while the stock shelf access door is in the opened state.

A machine tool includes: a body (130) including a processing area for a workpiece; an ejection part (125) configured to eject a coolant into the processing area; and a mist collector (40) configured to suck a substance included in air as a result of the coolant being ejected from the ejection part (125) into the processing area. The mist collector (40) includes a first filter (56) for removing the substance. The machine tool further includes: a drain (65) configured to discharge the substance that has passed through the first filter (56) to the body (130); and a suction mechanism (66) configured to suck the substance that has passed through the first filter (56) from the mist collector (40) into the drain (65).

A machine tool includes: a cover body defining a processing area inside the machine tool; an ejection part configured to eject a coolant into the processing area; a mist collector configured to collect a substance included in air as a result of the coolant being ejected from the ejection part into the processing area; a sensor provided outside the processing area and configured to detect the substance; and a mist collector control unit configured to cause the mist collector to start collection processing for collecting the substance when the substance is detected by the sensor.

A processing machine for the production of a dental workpiece from a blank, comprising a housing in which a first chamber and a second chamber are arranged, the second chamber being separate from the first chamber, a first holding device for a blank, the first holding device being arranged in the first chamber and being movable relative to the housing, a second holding device for a blank, the second holding device being arranged in the second chamber and being movable relative to the housing, and a processing device being movable relative to the housing, wherein a blank held in the first holding device and a blank held in the second holding device can be processed by the processing device.

A machining tool includes a light irradiator, a cover, and a light blocking filter. The light irradiator is to irradiate a workpiece to process the workpiece. The cover covers the light irradiator and the workpiece in the cover. The light blocking filter is configured to change light transmissivity of the light blocking filter in accordance with light from an inside of the cover, which the light blocking filter receives.

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.

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.

Provided is a highly practical machining system. The machining system is configured to include a base, and multiple machining modules which are detachably disposed on the base to be aligned with one another in a left-right direction. Machining is sequentially performed by the multiple machining modules with respect to a workpiece. At least one of the multiple machining modules is a vertical lathe module. It is possible to configure a compact system in which machining can be performed by a vertical lathe.

A machine tool system includes: a machine tool for machining a workpiece set on a table using a tool attached to a spindle; and a robot for gripping the workpiece. The robot is installed on the table and performs a setting operation for setting the workpiece on the table and a clamping operation for clamping the workpiece.

A chip conveyor includes: a cover body; a guide plate configured to guide chips, which are conveyed inside the cover body, so as to be directed from a chip receiving position toward a chip discharging position; a case attached to the cover body and having an internal space provided therein; and a float switch configured to detect, based on a coolant flowing from inside the cover body into the internal space, that a liquid level of the coolant inside the cover body is equal to or greater than a prescribed liquid level. The cover body includes a first space and a second space that are partitioned from each other by the guide plate. The cover body is provided with: a first opening allowing communication between the first space and the internal space; and a second opening allowing communication between the second space and the internal space.
