Description

Technical Field

[0001] The utility model relates specifically to the technical field of CNC machine tools, in particular to an automatic liquid distribution and filling device for CNC cutting fluid. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Formulated from a scientifically formulated combination of highly effective additives, cutting fluid offers excellent cooling, lubrication, rust prevention, oil removal, cleaning, corrosion protection, and easy dilution. It overcomes the drawbacks of traditional soap-based emulsions, such as summer odor, difficulty in dilution in winter, and poor rust prevention. It also has no adverse effects on lathe finishes, making it suitable for cutting and grinding ferrous metals and a leading grinding product. Cutting fluid outperforms saponified oil in all aspects, offering excellent lubrication, cooling, cleaning, and rust prevention properties. It is also non-toxic, odorless, non-corrosive to humans, equipment, and the environment.

[0003] Traditionally, cutting fluid is added to the machine tool water tank manually. This is fine if there are only one or two devices, but if there are more than a dozen or even dozens of devices, the efficiency is low. In addition, the usage of the cutting fluid storage tanks on each device is different, and it is impossible to replenish it in time, which is more troublesome to use. For this reason, we provide a CNC cutting fluid automatic liquid distribution and filling device. By installing a liquid level sensor in the cutting fluid storage tank, the cutting fluid can be replenished in time, and the corresponding branch opening and closing valve can be opened for replenishment according to the usage of the cutting fluid in different cutting fluid storage tanks. It is more convenient to use and effectively makes up for the above problems. Utility Model Content
