Cutting fluid for metal cutting and preparation method thereof

Abstract

The invention discloses a cutting fluid for metal machining and a preparation method thereof, and relates to cutting fluids. The cutting fluid for the metal machining is composed of a main agent and additional water. The main agent is composed of the following components, by volume: 5-15 parts of silicone oil, 5-15 parts of fuel oil, 1-5 parts of Turkey red oil and 0.5-3 parts of caustic soda solutions with the mass concentration of 10%, the using amount of the additional water is 10%-50% of the total volume of the main agent, and the fuel oil is one of gasoline, diesel oil and kerosene or mixed oil of more than two kinds of the gasoline, the diesel oil and the kerosene. The preparation method of the cutting fluid for the metal machining comprises the steps of mixing the Turkey red oil and the caustic soda solution evenly, then adding the mixed oil of the silicone oil and the fuel oil into the mixed liquid of the Turkey red oil and the caustic soda solution to obtain paste substances, and adding water into the paste substances and stirring until evenness is achieved. The cutting fluid for the metal machining has good cooling performance, cleaning performance, lubricating performance, anti-rust performance and the like, and is low in cost and free of pollution to environment.

Description

technical field [0001] The invention relates to a cutting fluid, in particular to a cutting fluid for cutting metal in machining and a preparation method thereof. Background technique [0002] In mechanical processing, various mechanical equipment are often used to use specific tools to complete the cutting process on metal workpieces. During the machining process, it is necessary to use cutting fluid to cool and lubricate metal workpieces and tools, so as to improve the machining accuracy of the workpiece and prolong the service life of the tools. In existing machining equipment, such as commonly used gear hobbing machines, gear shaping machines, arc gear machines, spline milling machines, etc., traditional machine oils are often used as cutting fluids to cool and lubricate workpieces and tools, but machine oils are relatively thick and viscous. The cooling performance is poor, the chips generated during processing are not easy to clean, and black smoke is emitted, which p...

In existing machining equipment, such as commonly used gear hobbing machines, gear shaping machines, arc gear machines, spline milling machines, etc., traditional machine oils are often used as cutting fluids to cool and lubricate workpieces and tools, but machine oils are relatively thick and viscous. Poor cooling performance, difficult to clean the chips generated during processing, and emit black smoke, polluting the environment. In addition, the cost of directly using engine oil is relatively high

Now there are also water-based chemically synthesized cutting fluids. This type of cutting fluid does not contain mineral oil and is made by adding water-soluble antirust agents, oily agents and other additives to the water. properties, but its lubricity and rust resistance are poor
