Aluminum and aluminum alloy cutting fluid thereof and preparation method thereof

Abstract

The invention discloses an aluminum and aluminum alloy cutting fluid. The cutting fluid is prepared from the following components in parts by weight: 10 to 15 parts of petroleum barium sulfate, 10 parts of petroleum sodium sulfate, 0.1 to 1 part of a PH conditioning agent, 10 to 15 parts of oleic acid, 1 to 5 parts of an anti-rust agent, 5 parts of a surfactant, 10 to 30 parts of glycerinum and the balance of industrial alcohol with the concentration of 95%. Through the adoption of the technical scheme, the relative molecular mass of petroleum barium sulfate is relatively large, the molecularmass of the cutting fluid is increased, and sufficient atomization of the cutting fluid is guaranteed; the PH conditioning agent is used for adjusting the pH value of the cutting fluid in the production process, so that the acid-base environment of the reaction of the ingredients of the cutting fluid in the blending process is guaranteed; the anti-rust agent can be used for effectively reducing the oxidized speed of a cutter, the service life of the cutter is prolonged, the temperature around the cutter can be absorbed by the atomized industrial alcohol, particularly, the temperature of cut aluminum skimmings is quickly reduced, high-temperature aluminum skimmings are prevented from being adhered to the cutter so as to influence the cutting precision and cutting force of the cutter.

Description

Technical field [0001] The invention relates to a metal cutting fluid, in particular to an aluminum and its alloy cutting fluid and a preparation method thereof. Background technique [0002] Because aluminum and its alloys are soft and have high plasticity, they tend to stick to the tool during cutting and form built-up edge on the tool. During high-speed cutting, welding may occur on the edge of the tool, which will cause the tool to lose its cutting ability and affect the machining accuracy and surface roughness. degree. In addition, the thermal expansion coefficient of aluminum alloy is large, and the heat of cutting can easily cause thermal deformation of the workpiece and reduce the machining accuracy. The cutting surface of aluminum alloy is easily oxidized and decolorized and black spots are generated during cutting, which greatly affects the efficiency of production and processing. [0003] Therefore, metal cutting fluids are often used in the machining of aluminum and i...

Problems solved by technology

[0002] Due to the soft quality and high plasticity of aluminum and its alloys, it is easy to stick to the knife during cutting, forming built-up edge on the cutting tool, and welding may occur on the cutting edge during high-speed cutting, which will cause the cutting ability of the cutting tool to be lost, and affect the machining accuracy and surface roughness.

In addition, the thermal expansion coefficient of aluminum alloy is large, and the cutting heat can easily cause thermal deformation of the workpiece and reduce the machining accuracy.

The cutting surface of aluminum alloy is easily oxidized and discolored and black spots are produced during cutting, which greatly affects the efficiency of production and processing

[0003] Therefore, in the machining process of aluminum and its alloys, metal cutting fluids are often used. Certain additives in the cutting fluids cause physical adsorption and chemical adsorption or chemical reactions between the tool and the workpiece to form low-shear strength lubricants. film, which inhibits the generation of built-up edge, effectively reduces the cutting force, and reduces the surface roughness of the workpiece. During the processing, the tool needs to be cleaned, which affects the processing efficiency. There are improvements in the existing technology
