Aluminum alloy cutting fluid manufacturers talk about the selection of aluminum alloy processing characteristics

The aluminum alloy cutting fluid manufacturer 'Jinnuo Lubricant' found that the flexibility of aluminum alloy (lower yield strength) will bring about two serious problems: 　　 1. Prone to adhesion. The aluminum particles adhere to the surface of the cutting tool, which seriously affects the roughness of the machined surface, or forms a 'bonded' built-up edge on the tool. The built-up edge will produce greater resistance and therefore requires higher cutting force. , Resulting in bad cutting marks. Bonding and material deformation often determine the cutting efficiency of aluminum alloys in machining. 2. Due to the high ductility of aluminum, it may form long strip-shaped cracks, which will block the cutting area and make the cutting process difficult. At the same time, the cut chips are difficult to be taken away by the cutting fluid. . Another issue that needs to be considered in aluminum alloy processing is its high thermal expansion coefficient. The heat generated by deformation and friction in machining can quickly spread to the workpiece, which makes it difficult to control the size of the workpiece, affects the machining accuracy of the workpiece, and requires greater cutting force.　　 If the machining cutting fluid has strong alkalinity and chemically reacts with aluminum, it will cause the emulsion to stratify. Therefore, in order to meet the increasing demand for aluminum alloy materials in mechanical processing and manufacturing, and to obtain higher labor productivity, it is very important to use professional aluminum processing cutting fluid technology to achieve a high level of lubrication and cooling effects. Therefore, special machining cutting fluid (such as EP226 aluminum machining cutting fluid from the aluminum alloy cutting fluid manufacturer 'Jinnuo Lubricant') should be used as the cooling lubricant in the aluminum processing.
