A processing method includes processing a metal wire rod using an emulsion lubricant that includes an oil and a nonionic surfactant at an oil-to-nonionic surfactant ratio of 1:0.3 to 0.9 (in mass ratio). The method may include purifying the emulsion lubricant after being used for processing the metal wire rod while maintaining the oil-to-nonionic surfactant ratio of 1:0.3 to 0.9 (in mass ratio) and then reusing the purified emulsion lubricant to process the metal wire rod.

The conveying device has a stationary supporting shaft, which extends in the at least one conveying channel in the longitudinal direction of the conveying channel, wherein a spiral element is rotatably supported on the stationary supporting shaft, and wherein the conveying device also comprises a drive for driving the rotational motion of the spiral element about the stationary supporting shaft.

A machine tool including a machining device configured to perform machining on a workpiece in a machining chamber, a chip conveyor including a reservoir tank into which machining chips generated by workpiece machining in the machining device flow, together with a coolant, the chip conveyor being configured to discharge the machining chips to an outside of the machine tool, a coolant tank in which the chip conveyor is incorporated, the coolant tank being configured to accumulate the coolant flowing out of the reservoir tank, a sub-tank provided to surround an outer side of a discharge window for the coolant, the discharge window being formed on a side surface of the reservoir tank, and a machining chip removal section in which a magnetic separator made of a magnet is accommodated in the sub-tank and an opening portion configured to filter the coolant is provided around the magnetic separator.

A cutting fluid intelligent recycling device, comprises a frame, a first-level filtering device, second-level filtering device, and clean liquid tank installed on the frame; the first-level filtering device being provided with a dirty fluid tank used for containing liquid, the dirty fluid tank having a dirty fluid suction device and dirty fluid treatment device; through the first-level and second-level filtering devices, the cutting fluid intelligent recycling device can remove the cuttings, iron powder, floating oil stain, cenobium, floccule and impurities in the cutting dirty fluid and also sterilize and deodorize the cutting fluid coolant to prolong its service life.

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 system for collecting shaving remnants and excess lubrication fluids emanating from a mechanical cutting machine, comprising a catch basin, drain filter, quick connection couplings, fluid reservoir, and pump system for reticulating captured lubricating fluid. The catch basin securely fastens to a cutting machine, while the removable backsplash is deployed at an upstanding angle relative to the catch basin in order to capture superfluous materials liberated from a pipe threading, reaming or cutting tool work piece. The backsplash doubles as a sealable lid capable of retaining the contents of the catch basin eliminating unwanted spillage and allowing for safe transport. The fluid is filtered and collected within the fluid reservoir, whereafter a pump draws the oil through a second filter element to reuse the lubricating fluid in the tool operation to create a closed loop system. Quick connect fittings compartmentalize the system to prevent leaks during maintenance or service.

A cylindrical filtration filter includes a cylindrical filter main body. The filter main body is constituted by at least two split filters. Each of the split filters has an arc shape in cross section. Each of the split filters includes a filter element for filtration and side frame bodies provided along side portions of the filter element. The side frame body of one of the two split filters adjacent to each other includes a first facing surface having an uneven shape. The side frame body of the other split filter includes a second facing surface having an uneven shape complementary to the first facing surface. The first facing surface and the second facing surface are fitted to each other when the filter main body is assembled.

The invention relates to a new centrifugal filter for filtering impurities from liquid. Embodiments comprise a cylindrical housing having: (1) a top flow guiding assembly with a top portion having a first liquid outlet, a threaded middle portion, a bottom portion having a plurality of spiral flow guiding grooves adjacent the bottom portion, and a channel through a longitudinal axis; (2) a water inlet flow guiding assembly having a middle portion with a liquid inlet, and a channel through a longitudinal axis; (3) a recessed flow guiding assembly having a channel through a longitudinal axis which forms a conical taper; and (4) an impurity flow guiding assembly having a channel through a longitudinal axis that forms a second liquid outlet; each assembly releasably attachable within the cylindrical housing through threaded means.

A centrifugal filter comprises a top flow guiding assembly, a water inlet flow guiding assembly, a recessed flow guiding assembly, and an impurity flow guiding assembly, in which a liquid entering from a water inlet opening of the water inlet flow guiding assembly can generate a convolution in an inner portion of the recessed flow guiding assembly. After convoluting to a bottom portion of the recessed flow guiding assembly, heavier impurity components comprised by the liquid flows downwardly into the impurity flow guiding assembly, and the liquid without the impurity components convolutes upwardly. Finally, the top cover portion outwardly discharges the liquid without the impurity components.

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.
