Problems solved by technology

[0003] The currently used fully synthetic aluminum alloy cutting fluid has certain defects in the application of DDG: 1. Insufficient lubricity, aluminum alloy has ductility, high heat generated by grinding, and high lubricity requirements, cutting fluid with good lubricity It can effectively reduce the heat; 2. The cleaning performance is not good. The aluminum powder produced by grinding is very large and fine. It is necessary for the cutting fluid to have good flushing performance and take away the aluminum powder in time so that it does not deposit on the surface of the aluminum plate.

Abstract

The invention relates to a fully synthetic aluminum alloy grinding fluid, which comprises the following components in % by weight: 10%-30% of alcohol amine, 2%-5% of pH stabilizer, 2%-5% of antirust agent, and 0.2%-1% etchant, 10%-30% lubricant, 2%-8% organic acid, 0.1%-0.5% sedimentation agent; the cloud point of the lubricant is 55°C-65°C, and the fully synthetic The defoaming time of the 5wt% dilution of the aluminum alloy grinding fluid is less than 30s. The fully synthetic aluminum alloy grinding fluid of the present invention has a tapping torque value of 134.9-144.6N, good lubricity, and can effectively take away the heat generated during the aluminum plate grinding process; it has the advantages of high cloud point and low foam, so that The grinding fluid has good cleaning performance and less foam generation; the contact angle with aluminum alloy is less than 30°, and the grinding fluid has good wettability to aluminum alloy, which is beneficial to improve the cleaning effect of aluminum chips, so it is very suitable for use Processed on aluminum plate DDG.

Description

technical field [0001] The invention relates to the field of metal processing grinding fluid, in particular to a fully synthetic aluminum alloy grinding fluid and a preparation method thereof. Background technique [0002] The current aluminum plate processing, especially the 3C industry, mostly adopts full numerical control high-efficiency double-end precision grinding machine (DDG) to replace the original computer numerical control machine tool (CNC) high-speed milling process, which not only saves costs, but also improves efficiency. DDG precisely grinds the aluminum plate into a regular three-dimensional shape through double-end high-speed grinding to facilitate subsequent CNC finishing. Double-face high-speed grinding is a progressive grinding method, using the small grinding angle set when the two-end grinding wheel is installed, the grinding allowance is removed in sequence, and the layer-by-layer removal grinding is realized. [0003] The currently used fully synthe...
