Description

Technical Field

[0001] The utility model relates to the technical field of engraving and milling machines, in particular to a cooling liquid circulation mechanism for engraving and milling machines. Background Art

[0002] A milling machine is a type of CNC machine tool. It's generally considered a CNC milling machine that uses small tools and a high-power, high-speed spindle motor. While engraving machines excel at carving, they struggle when working with hard materials. The advent of milling machines bridges the gap between the two.

[0003] Announcement No. (CN210633370U) discloses a coolant circulation mechanism for an engraving and milling machine. The coolant enters the frame through the liquid inlet pipe and is located below the partition. Then, under the action of the pump body, the coolant enters above the partition through the first pipe, and then passes through the first filter, the second filter and the third filter in sequence to enter the third pipe. Then, the ultraviolet lamp can sterilize the coolant, and liquid nitrogen can cool the coolant. The above device uses the first filter, the second filter and the third filter to filter impurities in the coolant, but it is difficult to clean the impurities after filtration and needs to be improved.
