The aluminum alloy is soft in texture, and it is easy to stick to the cutting tool during cutting, forming chip accumulation. The thermal expansion coefficient of aluminum alloy is large, and the cutting heat is quickly transferred to the workpiece, which is easy to cause thermal deformation, the size of the parts is difficult to control, and the machining accuracy is reduced. It is easy to oxidize in air and acid/alkali environment. The chemical properties of aluminum are relatively active. When choosing cutting fluid for CNC machining of aluminum, the characteristics of aluminum and the problems that may occur during processing should be considered. The Characteristics Of Aluminum And Possible Problems In Machining So, how to choose cutting fluid for aluminum machining? It is necessary to ensure that the cutting fluid has good lubricity and rust resistance, but also has good stability, filtration and easy maintenance, so that the products can meet the requirements and reduce the cost of cutting fluid at same time. The choice of cutting fluid for aluminum machining is very important. In order to ensure successful processing, a suitable aluminum cutting fluid is required. If you do aluminum machining without any coolant and lubricant, various problems may interfere with processing and affect product quality.
