Example Embodiment

[0032] The preparation steps of the metal working fluid involved in the present invention are as follows:

[0033] Add mineral oil, lubricant, and emulsifier in sequence to container 1, heat to 50-60°C, and stir for 2 hours. Add water, rust inhibitor, biological inhibitor and copper etchant in sequence to container two, and stir until uniform and transparent. Slowly add the mixture in container two into container one, stir for 30 minutes, add bactericide and coupling agent, and stir until uniform and transparent. Finally, add defoamer and stir until uniform and transparent.

Abstract

The invention relates to a semi-synthetic metal working fluid special for aluminum and aluminum alloys, which has an excellent lubricating property and protective properties for aluminum and various aluminum alloys. The excellent lubricating property of the metal working fluid is manifested by simultaneously satisfying various processing modes of the aluminum alloys, such as turning, milling, drilling, tapping and the like. The excellent protective properties for the aluminum and the aluminum alloys are manifested by processing various aluminum alloys, generating no corrosion to the aluminum alloys and ensuring the requirements on the luminance brightness of the aluminum alloys. Besides, the metal working fluid also has excellent anti-rust properties and anti-foaming properties, and is added with a biological inhibitor which can effectively inhibit the growth and the reproduction of bacteria, prolong the service life of the metal working fluid and reduce the cost.

Description

technical field [0001] The invention relates to a metal processing fluid specially used for aluminum and aluminum alloys, which has excellent lubricity and aluminum protection performance and can satisfy various processing methods at the same time. technical background [0002] Aluminum alloy materials are widely used in the manufacturing and processing of mechanical parts. Compared with most steel and cast iron materials, aluminum alloy has an obvious advantage: lower yield strength. In addition, the thermal conductivity of aluminum alloy is twice as high as that of copper alloy, which reduces the cutting temperature. Therefore, during machining Lower cutting forces are required, allowing higher cutting speeds and feed ratios without excessive tool wear. [0003] However, as far as the cutting performance of aluminum alloy is concerned, its flexibility will cause two serious problems: first, it is prone to bonding. Aluminum particles bond to the surface of the cutting too...
