CNC machine tools, engraving machines, metal processing and glass cutting are inseparable from cutting fluid. It not only protects the machine, but also uses cutting fluid in the machining process to reduce the friction between the machine and the workpiece in the machining process. It can be seen that the importance of cutting fluid lubrication performance.
The friction and wear in cutting process is complex, including fluid lubrication, boundary lubrication, mixed lubrication between fluid lubrication and boundary lubrication and elastic fluid lubrication. Different cutting processes. The same cutting process has different cutting speeds, different workpiece materials and different proportions of various lubrication forms, which is difficult to meet the lubrication requirements of cutting fluid. For example, metal grinding and drilling processes generally require that the lubricating performance of cutting fluid is higher than that of metal cutting and grinding. The cutting of ferrous metals requires that the lubricating performance of cutting fluid is better than that of non-ferrous metals. Therefore, the requirements for cutting fluid will be higher.
In the process of selecting cutting fluid, we should not only consider the single performance effect, but also choose suitable ones, such as cooling, rust prevention, cleaning, etc., in order to obtain better processing effect and provide process quality.
