In the process of precision hardware parts processing, lubrication and cooling technologies play a vital role. They can not only ensure the smooth progress of the processing process, but also significantly improve the processing accuracy and surface quality of parts. This article will explore the lubrication and cooling technologies in precision hardware parts processing in depth.Lubrication technology mainly forms a lubricating film on the processing part to reduce the friction and wear between the tool and the workpiece. This lubricating film can not only reduce the cutting force and cutting heat, but also effectively prevent the growth of cutting tumors, thereby improving the quality of the processed surface. In precision hardware parts processing, commonly used lubricants include vegetable oils, animal oils, fatty acids, and specially treated mineral oils. These lubricants can penetrate into the tiny gap between the workpiece surface and the tool to form a strong adsorption film to achieve efficient lubrication.Cooling technology mainly reduces the temperature of the processing part to prevent the workpiece from deformation or burns due to overheating. In the process of high-speed cutting and heavy cutting, the temperature of the workpiece and the tool will rise sharply due to the generation of friction and cutting heat. If cooling is not carried out in time, it will not only affect the processing accuracy and surface quality, but also cause premature wear and damage of the tool. Therefore, the use of appropriate cooling technology is crucial to ensure the stability and reliability of the processing process.In precision hardware parts processing, commonly used cooling methods include wet cooling and dry cooling. Wet cooling is mainly achieved by spraying cooling lubricant, which can quickly take away the heat generated by the processing part and play a role in lubrication and cleaning. Dry cooling mainly relies on media such as air or inert gas for cooling. This method is suitable for some processing processes that have special requirements for cooling lubricants.It is worth noting that when selecting lubrication and cooling technology, it is necessary to comprehensively consider multiple factors such as processing properties, workpiece materials, machine tool characteristics, and processing accuracy requirements. For example, for rough processing of tough materials such as steel parts, wet cooling lubricants such as emulsions are generally used; while for fine processing of brittle materials such as cast iron, low-viscosity lubricants such as kerosene may be used for lubrication and cooling.In summary, lubrication and cooling technology plays an irreplaceable role in precision hardware parts processing. By rationally selecting and applying these technologies, processing efficiency and quality can be significantly improved, providing strong guarantees for the production of precision hardware parts.
