A magnesium alloy cutting fluid

Abstract

The invention discloses a magnesium alloy cutting fluid which is prepared from the following raw materials in percentage by weight: 20-30% of mineral oil, 5-10% of oleic acid, 2-5% of ricinoleic acid, 0.2-0.5% of polyether, 6-10% of boric acid, 1-5% of triazine derivative, 1-4% of hydroxyacrylate, 15-25% of polyethyleneglycol, 0.1-2% of monoethanolamine, 1-3% of triethanolamine and the balance of water. The magnesium alloy cutting fluid has the advantages of excellent corrosion resistance, excellent lubricating property and excellent abrasion resistance, protects the cutter, enhances the surface quality of the workpiece, greatly takes the heat generated in the machining process away, lowers the temperature of the machined surface, effectively prevents the workpiece from curling and deformation due to high temperature, overcomes the defects of high-temperature inflammability and the like in the magnesium chips, and greatly enhances the machining accuracy of the workpiece.

Description

technical field [0001] The invention belongs to the technical field of metal cutting fluid, in particular to a magnesium alloy cutting fluid. Background technique [0002] Magnesium alloy has light weight, relatively high strength and rigidity, and is recyclable and has good machinability. It has been widely used in the fields of automobiles, mobile phones, and computers. However, due to the low ignition point and high activity of magnesium alloys, during the cutting process, due to the contact between the rake face of the tool and the cutting surface, severe friction occurs, the pressure is high, and the temperature is also high. , and because the resulting cutting is relatively small, if the cooling is not sufficient at this time, cracks, low-temperature welding, or even combustion will appear on the surface of the magnesium part, and the quality of the surface of the workpiece is low at this time. [0003] The magnesium alloy cutting fluid in the prior art has insufficie...

It has been widely used in the fields of automobiles, mobile phones, and computers. However, due to the low ignition point and high activity of magnesium alloys, during the cutting process, due to the contact between the rake face of the tool and the cutting surface, severe friction occurs, resulting in high pressure and high temperature. , and because the resulting cutting is relatively small, if the cooling is not sufficient at this time, cracks, low-temperature welding, or even combustion will appear on the surface of the magnesium part, and the quality of the surface of the workpiece is low at this time

[0003] The magnesium alloy cutting fluid in the prior art has insufficient anticorrosion performance on magnesium alloys, and corrosion phenomena such as discoloration are prone to occur, which affects its use
