Description

technical field [0001] The invention relates to the technical field of CNC machine tool cutting fluid, in particular to a high-pressure, low-foam general-purpose cutting fluid for metal processing of CNC machine tools and a preparation method thereof. Background technique [0002] Metal cutting fluid is a general term for various oils that provide lubrication, cooling, cleaning and rust prevention for machining in metal cutting and grinding. Cutting fluid is an important supporting material for CNC machine tool processing. The purpose of using metal cutting fluid is to reduce the cutting force and the friction between the tool and the workpiece, take away the heat generated in the cutting area in time to reduce the cutting temperature, reduce tool wear, improve tool durability, thereby improving production efficiency and improving the surface of the workpiece The roughness ensures the machining accuracy of the workpiece and achieves the best economic effect. Therefore, the ...

AI Technical Summary

Problems solved by technology

When machining with traditional semi-synthetic cutting fluid under high-speed and high-pressure conditions, a large amount of foam will be generated on the surface of the cutting fluid, which will seriously affect the processing quality and precision; although the use of fully synthetic cutting fluid can basically solve the foam problem, However, the lubricating performance is difficult to meet the processing requirements; if emulsified cutting fluid is used, the cleaning and sedimentation performance will not meet the requirements, and it is necessary to continuously add defoamers to the cutting fluid to eliminate the large amount of foam generated during processing. increased economic costs

[0003] A water-based low-foaming semi-synthetic cutting fluid for high-pressure high-efficiency processing as described in the authorized announcement number CN103497821B, although it saves the economic cost of the cutting fluid to a certain extent because it does not add a defoamer, it is used when non-ferrous metals or ferrous metals There are still relatively obvious foams in the application and medium and heavy-duty processing. It adopts an environmentally friendly dispersant, which solves the processing lubricity of non-ferrous metals and ferrous metals and the problem of chip coagulation, reduces the flocculation effect, and inhibits the iron filings in the process. Agglomeration effect on the machine table, but also reduces its anti-corrosion and anti-rust properties
