A processing discharge liquid filtration device enhances filtration capacity for filtering a discharge liquid discharged from a processing device. The processing discharge liquid filtration device includes a dirty tank that stores a discharge liquid containing cutting chips, a dirty tank pump that pumps the discharge liquid stored in the dirty tank to a screen filter for primary filtration processing that recovers the cutting chips mixed into the discharge liquid, and a cutting chip recovery container that contains the cutting chips recovered by the screen filter. The processing discharge liquid filtration device eliminates the time and effort to replace the filtration member or filter and keeps the quality of the filtered discharge liquid constant.

A separator apparatus is provided for a cutting machine which separates chips from coolant, wherein the separator includes a fluid chamber into which an airborne mixture of chips and coolant driven by an airflow enters via an entry port, the separator apparatus being configured to: sufficiently slow the speed of the airborne mixture once inside the chamber so that the chips and coolant separate out from the airflow; retain the chips and coolant released from the airborne mixture in the fluid chamber; and allow air from the airborne mixture to exit the fluid chamber via an air outlet; wherein the fluid chamber includes a chip collector which captures the chips and enables the chips to be separated and removed from the coolant in the chamber; and wherein the fluid chamber includes a coolant outlet through which coolant, from which the chips have been removed, is able to exit.

A machining system includes: a working machine that machines an article while supplying a dielectric working fluid to the article; a robot that transports the machined article from the working machine; a controller that controls the robot; and a recessed wall part that is provided outside the working machine so as to demarcate the transport path of the article. The robot includes a gripping part that grips the article and a rotating part that rotates the gripping part. The controller is configured to move the gripping part with the machined article along the transport path while rotating the gripping part in the recessed wall part by means of the rotating part.

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.

In order to minimize the maintenance effort that accompanies discharge and comminution of a chip, an apparatus for discharge and comminution of a chip has a chip guide and a comminution apparatus, to which the chip guide guides the chip along a chip path. The chip guide has a guide channel that circumferentially surrounds the chip path having a channel inlet and a channel outlet, wherein the guide channel has a maintenance opening in addition to the channel inlet and the channel outlet. Furthermore, a method for discharge and comminution of a chip for this purpose services the guide channel by way of the maintenance opening after discharge and comminution of a chip having a predetermined chip length.

A machine tool with a chip evacuation device according to the present invention is provided with a cleaning mechanism for cleaning a part or the whole of the chip evacuation device and a control unit configured to control respective operations of the chip evacuation device and the cleaning mechanism in association with each other. By using an electric motor, such as a synchronous motor capable of position control, as a power source for the chip evacuation device, the respective operations of the chip evacuation device and the cleaning mechanism can be associated with each other to effectively clean the chip evacuation device.

A chip conveyor which discharges chips produced by a machine tool from the inside of a splash guard is provided inside the splash guard that prevents the chips from being scattered. A chip carrying unit of the chip conveyor is attached to the splash guard so as to be movable with respect to the splash guard in the up and down direction. Accordingly, even when the chips are stuck between the chip carrying unit and the splash guard, the chip carrying unit automatically moves, and hence the chip stuck state may be resolved.

A machining system with a configuration in which working machines, including a machine tool such as a lathe, are configured to be disposed in a line and multiple working machines perform operations on one work in order such that practical utility of the machining system is enhanced. 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.

A blast gate for a vacuum system includes a chassis connectable to a duct and defining a flow passage therethrough, and a gate connected to the chassis and rotatable about a central axis. The gate includes a first portion, an intermediate portion and a second portion spaced apart circumferentially about the central axis. The first portion defines a flow aperture, the intermediate portion defines an auxiliary flow aperture, and the second portion includes a partition. Each of the first portion, second portion and third portion is selectively rotatable into fluid alignment with the flow passage. The blast gate further includes a motor connected to the gate and selectively operable to rotate the gate about the central axis.

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.
