Abstract

 Based on the characteristics of aluminum alloy and the demanding requirements of high-gloss machining quality,a polyether polyol ester lubricant was synthesized using castor oil acid and methoxy polyethylene glycol as raw materials, and a new type of synthetic high-gloss cutting fluid was developed using a maleic anhydride composite of boric acid and ternary carboxylic acid as rust inhibitors.Comparative studies were conducted on the lubrication performance, corrosion resistance to aluminum alloy, rust prevention, defoaming, and hard water resistance of this synthetic high-gloss cutting fluid against commonly available imported and domestic cutting fluids on the market.Results showed that compared with imported and domestic cutting fluids,the maximum non jamming load PB value of high-gloss cutting fluid was 735 N,which was better than imported cutting fluid (686 N) and domestic cutting fluid (588 N).The threading torque value of the high-gloss cutting fluid was the lowest, followed by the imported and then the domestic diluted cutting fluid, suggesting superior lubrication of the high-glosscutting fluid.The 24 h corrosion test showed that the corrosion resistance of high-gloss cutting fluid to aluminum alloy was grade A, which reached the level of imported cutting fluid and is better than domestic cutting fluid.Additionally, the high-gloss cutting fluid exhibited commendable rust prevention, excellent defoaming, and favorable hard water resistance.
