A screw conveyor that appropriately discharges chips inside cutting fluid includes: a main body in the form of a container provided with a storage tank; a screw rotatably assembled inside the storage tank; a discharge pipe formed at a rear side of the main body and connected to the storage tank; an inlet section configured to receive the chips and the cutting fluid into the storage tank at a front side; a guide plate configured to guide the chips and the cutting fluid to the screw; a screw cover provided with multiple fine holes configured to cover a space above the screw; and an opening formed in the storage tank at a position higher than the screw cover such that the cutting fluid enters inside the main body.

A detecting system includes a tank unit, a pump and a controller. The tank unit includes a tank and an ultrasonic sensor. The tank stores machining fluid. The ultrasonic sensor is disposed on the tank, and measures a distance to a surface of the machining fluid stored in the tank and outputs a distance signal based on measurement of the distance. The pump is disposed on the tank, is connected to a nozzle of a machine tool, and pumps the machining fluid from the tank to the nozzle for spraying the machining fluid on a workpiece. The controller is connected to the machine tool, the ultrasonic sensor and the pump, and receives the distance signal, performs a liquid-level analysis based on the distance signal, and outputs to the machine tool a result of the liquid-level analysis.

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 swarf handling apparatus installed in a machining tool that performs machining operation accompanied with production of stringy swarf includes a swarf catching device. The swarf catching device includes a holder unit that holds the stringy swarf when the stringy swarf makes contact with the holder unit. The swarf catching device causes the holder unit to be floated in a region around a machining point in such a manner that the position of the holder unit is varied relative to the machining point, for catching the stringy swarf in the holder unit.

A chip conveyor, which reduces the discharge amount of a cutting liquid by a simple structure, includes a storage tank in which chips and cutting liquid are stored; an endless conveyor main body which connects both end portions of a number of hinge plates in a front-back direction to each other by a hinge and circularly moves through a climbing portion from an inside of the storage tank by a driving mechanism; and a control device which controls driving of the driving mechanism, in which, in the conveyor main body, multiple scraping plates formed in a standing state with respect to the hinge plate are disposed with an interval in an advancing direction, and in which the scraping plates are formed along a width direction of the conveyor main body and have one or more through portions through which the cutting liquid passes within the width interval thereof.

Disclosed is a system for removing and collecting finely cut chips. The system can scrape and collect cutting oil and finely cut chips accumulated under a cutting apparatus using a scraper moving in a predetermined direction, separately discharge and reuse only cutting oil using a holed plate having holes smaller than finely cut chips, and separately collect and handle only the finely cut chips collected by the scraper.

A machining system with a configuration in which working machines, including a machine tool, are configured to be disposed in a line, and in which multiple working machines perform operations on one work in order, is provided. The machining system includes: a base; and multiple working machine modules which are mounted on the base and are arranged in an arrangement direction, and has a configuration in which each of the multiple working machine modules is capable of being drawn out from the base along a track extending in an intersecting direction intersecting with the arrangement direction.

Provided is a device discharging chips, which is configured to allow smooth transfer because it is possible to absorb transformation of connecting pins due to a force generated while chain belts are operating as well as smoothly discharging a coolant and chips.

An apparatus for collecting dust from a cutting unit is provided. The apparatus includes a rotary valve operatively connected to the cutting unit, a conduit in fluid communication with the rotary valve, and a compacting machine disposed downstream from the conduit and configured to receive dust from the conduit. A blower is configured to pull air downstream to carry the dust into the compacting machine. The compacting machine produces a compact from the dust.

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.
