Description

technical field [0001] The invention belongs to the field of cutting fluid, and in particular relates to a magnesium alloy cutting fluid and a preparation method thereof. Background technique [0002] Magnesium alloy has light weight, relatively high strength and rigidity, and is recyclable and has good machinability. Therefore, magnesium alloys have gained widespread attention in many fields such as aerospace, automobiles, and electronic appliances. [0003] 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. Cooling will cause cracks and low-temperature welding or even burning on the surface of the magnesium part. At this time, the quality of the surface of the workpiece is low. [0004] Therefore, water-based magnesium alloy cutting fluid has gradually become a ...

AI Technical Summary

Problems solved by technology

In the current existing technology, magnesium alloy cutting fluid has three major technical difficulties: one is that its material is quite active, and it must be prevented from being corroded by water during and after processing; the other is that magnesium alloy is prone to produce powder during processing. Magnesium hydroxide precipitates on the guide rails and work surfaces of machine tools; third, magnesium alloys are continuously dissolved into the cutting fluid, and the hardness of the cutting fluid will gradually increase, so the cutting fluid must have a very high resistance to hard water, so that the cutting fluid is not easy to appear demulsification and delamination
