Application and maintenance of metal working fluids for the aircraft manufacturing industry The metal processing of the aircraft manufacturing industry includes the processing of aviation thin-wall parts, aviation aluminum parts (7 series aluminum), titanium alloy/superalloy material processing, and high magnesium alloy processing. The selection of cutting fluid needs to consider many factors such as material, processing method (grinding, drilling, turning, milling, wire, broaching), water quality requirements (soft, suitable (100PPM-200PPM), hard), rust prevention requirements (rust prevention cycle between processes), processing visibility requirements (whether the processing process needs to be observed), environmental protection (odor, element content, skin adaptability) and so on. The long-term use of cutting fluid needs to meet the following three conditions: The correct selection of cutting fluid products; Cutting fluid daily maintenance method is correct; Reasonable equipment (removing oil slick equipment, centralized liquid supply equipment, etc.). 6061 Typical case of solving aluminum processing residue problem There is no obvious residue on the surface of the workpiece processed by the synthetic liquid, and it is more smooth and clean. It can be directly anodized after rinsing with water (no need to clean with water-based cleaning agent), and the anodizing pass rate reaches 100%. According to the statistics of machine tool operators, the use of raw emulsion and synthetic liquid are about 10 days to replace a tool, the impact on tool life is not much. The machine tool has no corrosion and rust phenomenon, compared with the machine tool with emulsion, the cutting fluid has less wall residue, the window visibility is better, the machine is cleaner and the production environment is clean.
