The invention relates to a method for the chip-removing production or machining of a workpiece by means of a tool, in which method a liquid, which mixes and accumulates with the chips produced during the machining process, is used for lubricating and/or cooling the machining process, and the chips are discharged from the accumulation counter to the downhill force along a discharge path by means of a magnetic force, wherein a return flow of the liquid carried by the discharged chips occurs due to the downhill force, and the return flow is deflected out of the discharge path and/or the discharge path has at least one point at which the supporting surface is temporarily withdrawn from the discharged chips.

A flushing duct is installed on both sides of a table of the machine tool in a longitudinal direction of the table, a slope duct is inclinedly disposed below the flushing duct toward the coolant tank, each bottom surface of the flushing duct and the slope duct is formed with a V-shaped inclined surface and a streamlined bending portion to make flows of the coolant containing the microchips smooth, and a coolant supply valve is installed at a rear end of the flushing duct to facilitate flows of the coolant being discharged by supplying additional coolant. Further, a coolant tank is installed below the slope duct, a filter is installed in the coolant tank for filtering the microchips in the coolant. The coolant containing the microchips is transported through a return pump to a centrifugal separator device where the microchips contained in the coolant are centrifugally separated. A refined coolant through centrifugal separation is supplied to the machine tool, thereby preventing abnormal wear due to penetration of the microchips into rotating and sliding portions of the machine tool.

This application relates to lubrication, and more particularly to an external cooling MQL manipulator and a machine tool and a lubrication method using the machine tool. The external cooling MQL manipulator includes a suspension structure, a robot arm, a controller and an oil mist generator. The suspension structure fixedly connects the robot arm and a frame, and a nozzle is provided on a free end of the robot arm; an oil mist generator is connected to the nozzle for ejecting oil mists to a processing area. When the machine tool works, the controller selects the corresponding lubrication parameters according to the processing parameters such as the cutter type and the workpiece material. The first motor and the second motor are controlled to rotate by the controller according to real-time changes of the processing positions detected by the detecting component, thereby adjusting the position of the nozzle.

A machine tool for machining a workpiece clamped in the working space of the machine tool by means of a tool. The machine tool includes a machine bed, which has a chip collection region having at least one conveying channel open on the working space side for collecting chips that drop during the machining of the workpiece, and a conveying device for leading away chips that have dropped into the chip collection region in the at least one conveying channel. 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 system and process for recycling machining waste into a solid/scrap material component and a recyclable machining coolant. The system and process comprise collecting the waste machining waste and mechanically separating the machining waste into a solid/scrap material component and a machining waste liquid component. The machining waste liquid component is decanted to separate oils and solids from the recyclable machining coolant. The machine recyclable machining coolant is then filtered through at least a first filter and preferably a second, finer mesh filter. The recyclable machining coolant is then exposed to UV light to kill bacteria and microorganisms. Lastly, ultrapure water is added to dilute the recyclable machining coolant and form the recycled machining coolant. If desired, a virgin machining coolant can be added to the recycled machining coolant, to replenish any additive(s) stripped during the recycling process, prior to resale of the recycled machining coolant.

The device can separate, recover and reuse oil mist particles in the air.

A cutting fluid tank configured to recover cutting fluid from a machine tool includes a first parallel passage and a second parallel passage configured to recover the cutting fluid discharged from the machine tool and parallelly arranged to each other, and a communication passage configured to communicate the first parallel passage and the second parallel passage at ends of the first parallel passage and the second parallel passage, wherein the cutting fluid tank flows the cutting fluid through the first parallel passage and the second parallel passage in opposite directions to each other, and supplies the cutting fluid from the end of the second parallel passage to the machine tool, two inflow and outflow portions are adjacently arranged configured to flow the recovered cutting fluid to the first parallel passage, and each of inflow and outflow portions formed so as to flow the cutting fluid from different direction to each other, and flow the cutting fluid to the first parallel passage.

A mist collector includes: a filter that collects mist; a nozzle including an ejection port capable of ejecting a coolant, the nozzle being disposed to cause the ejection port to be opposite to the filter; and a motor that causes the filter to move, to cause a position on the filter to which the ejection port is opposite to change.
