Cutting fluid tank for machine tool

Abstract

Provided is a cutting fluid tank for a machine tool, which is capable of sufficiently collecting and removing sludge mixed in a cutting fluid even when a chip conveyor or the like is disposed in a tank main body, and with which a location where sludge remains accumulating on a bottom of the tank main body is less likely to occur even when an operation is restarted after being suspended. The cutting fluid tank includes: a tank main body, in which the sludge-containing cutting fluid discharged from the processing portion of the machine tool flows into and is stored from the inflow portion; a first circulation pump disposed at a position where the flow rate of the sludge-containing cutting fluid in the tank main body is relatively fast and has an upward suction port; a sludge transfer nozzleconfigured to eject the sludge-containing cutting fluid pumped out by the first circulation pump, toward a sludge collection pump which is arranged at a position where the flow rate of the sludge-containing cutting fluid in the tank main body is relatively slow, and has a suction port facing the bottom of the tank body; a second circulation; and first agitation nozzles configured to eject the sludge-containing cutting fluid that is pumped out by the second circulation pump, toward predetermined points in the tank main body.

Description

technical field [0001] The invention relates to a cutting fluid tank used by working machines such as machining centers and lathes. Background technique [0002] For example, in a machine tool that performs cutting such as a machining center or a lathe, a cutting fluid (coolant) is generally used for lubricating and cooling a tool, and discharging sludge. [0003] The cutting fluid sprayed into the machining chamber (processing section) where the workpiece is cut is discharged from the machining section together with sludge such as chips scraped off from the workpiece. The discharged cutting fluid flows into the main body of the cutting fluid tank after separating and removing the larger substances in the sludge mixed with it through the chip conveyor or filter, and temporarily stores it. supply. [0004] Here, small sludge that cannot be separated and removed by the chip conveyor or filter may flow into the tank body together with the cutting fluid, and if the cutting flu...

AI Technical Summary

Problems solved by technology

[0004] Here, small sludge that cannot be separated and removed by the chip conveyor or filter may flow into the tank body together with the cutting fluid, and if the cutting fluid mixed with the sludge is supplied to the processing part through the coolant pump, machining failure may occur. In addition, because the sludge mixed with the cutting fluid accumulates at the bottom of the tank body, there is a possibility that the cutting fluid will be corrupted and the working environment will be damaged.
