A filtration system includes a bin having a base, an inlet configured to receive contaminated fluid, and an outlet. The bin further includes a plurality of metal chips positioned on a plate, such as a perforated plate, above the base of the bin. The contaminated fluid, such as contaminated coolant, may flow through the inlet toward the base of the bin and pass up through the plate and the chips to filter away contaminations.

A machine tool includes a machine body; a control panel; a peripheral device; a peripheral device frame that is adjacent to one side surface of the machine body and for which the top view of the area for installing the peripheral device is roughly rectangular, wherein the two corners of one end of the rectangle are supported, and the corner of the other end of the rectangle that is closer to the machine body is supported from below but the corner of the other end of the rectangle that is farther from the machine body is not supported from below; and a coolant filtration and supply device with a coolant tank disposed below the peripheral device frame so as to accept coolant discharged from the machine body, the coolant filtration and supply device being installed so as to be able to move toward and away from the machine body.

A waste collecting apparatus and workpiece processing systems, relating to the field of machining processes, are provided. An exemplary waste collecting apparatus may include a collecting body, a feeding pipe and a liquid discharging pipe in communication with the collecting body, and a separating mechanism provided within the collecting body, wherein the separating mechanism allows liquid waste to pass through while retaining solid waste. Further, via provision of a separate mechanism, the waste may be subjected to a solid-liquid separation, e.g., a liquid waste may be obtained from the liquid discharging pipe, and a solid waste may be obtained from the collecting body. According to aspects herein, a solid-liquid separation process is no longer required at subsequent/central processing of the waste. Moreover, since the collecting body retains only the solid waste, the time interval for centrally processing the waste increases, reducing labor intensity and improving work efficiency.

A coolant processing apparatus removes sludge from a coolant discharged from a machine tool. The coolant processing apparatus includes a first reservoir and a second reservoir provided in a tank for retaining the coolant. The first reservoir includes a flow path in which the discharged coolant flows, and a portion downstream of the flow path to retain the coolant such that the sludge remains in the first reservoir. The flow path has at least one bend to bend a flow of the coolant at least once in a horizontal direction. The second reservoir retains the coolant flowing out from the first reservoir. A boundary wall is provided between the first and second reservoirs, at a location downstream of the at least one bend of the flow path, and has such a height that allows a supernatant of the coolant in the first reservoir to flow into the second reservoir.

A cutting fluid circulation device includes a tank reservoir, a drum filter, and a pump. The tank reservoir stores cutting fluid discharged from a machine tool. The drum filter is disposed in the tank reservoir. The drum filter performs as a primary filter that filters cutting fluid. The pump pumps up cutting fluid in the tank reservoir. An annular flow channel in which the cutting fluid filtered by the drum filter circulates is formed in the tank reservoir. A part of the cutting fluid pumped up by the pump is fed to the drum filter, used for cleaning the drum filter, and then returned to the annular flow channel, and a part of the remaining cutting fluid is fed to a secondary filter disposed outside the tank reservoir, filtered by the secondary filter, and then returned to the annular flow channel.

A coolant tank includes: a tank main body configured to store a coolant discharged from a processing machine; a vortex flow generator that creates a vortex flow of the coolant in the tank main body; and a float configured to float on a liquid surface of the coolant stored in the tank main body. An outer peripheral portion of the float has a shape conforming to a shape of an inner peripheral wall surface of the tank main body and forming a gap between the outer peripheral portion and the inner peripheral wall surface.

A device (A) to detect a filtering means (14) in a water treatment unit (1) including at least one signal transmitter (13) and at least one sensor (12) to detect a signal from the signal transmitter (13), whereby the water treatment unit (1) can be set at least in a work mode or in a sleep mode. The water treatment unit (1) is configured in such a way that the work mode can only be set if at least one signal which is emitted by the signal transmitter (13) is detected by the sensor (12). A filter (14) and a suction head (3) for use in the device (A). A system including a filter (14) and a suction head (3) for use in the device (A).

Disclosed is an artificial tooth machining apparatus which protects a workpiece and first and second tools from heat and frictional contact that may occur when the workpiece is machined and enhancing machining precision by supplying water or air to the tools by a supply unit, a first nozzle portion, and a second nozzle portion, which has a lifespan lengthened by preventing chips of the workpiece or water or air from being introduced to a mechanism operation part of a base part by a discharge unit and a blocking unit, and which prevents a collision between the first tool and the second tool during machining of the workpiece by a tool collision preventing controller.

A pump having a cutting wheel (20) and a pre-cutter (26) driven by a shaft portion (24) that projects axially from the cutting wheel (20) and has a plurality of wings (28) that extend radially from the shaft portion (24), wherein the wings (28) differ in their axial arrangement on the shaft portion (24).

The cutting fluid supply device of a machine tool includes a storage tank of a cutting fluid, a cutting fluid discharge port which discharges the cutting fluid, at least one pump which feeds the cutting fluid to the cutting fluid discharge port, a first filter, a second filter which has filter performance different from the first filter, a path switching unit which switches the paths of the cutting fluid and a control unit, and the control unit controls the pump and the path switching unit so as to switch, as the paths, to a first path along which the cutting fluid is fed without being passed through the filters, a second path along which the cutting fluid is passed through the first filter and is fed and a third path along which the cutting fluid is passed through the second filter and is fed.
