Discussion on Mini-Lubrication Processing of Engraving and Milling Machine
During the milling process of the engraving machine, a large amount of small debris will be generated. The debris splashing at the work site can be seen everywhere. Some milling debris adheres to the surface of the workpiece, which affects the quality of engraving. At the same time, traditional engraving machines generally use a large amount of emulsion spray This kind of hydraulic lubrication cooling, this way has some shortcomings. The processing of light-cutting parts also requires the hydraulic system to be turned on, and a large amount of emulsion is sprayed, resulting in a decrease in the utilization efficiency of the hydraulic system. The use of emulsification cooling for high-speed rotating milling cutters will generate centrifugal force, which makes it difficult for the emulsion to reach the lubrication point directly, and at the same time causes a large amount of emulsion to splash around. When the equipment is used for a long time, the anti-leakage structure will age, and the emulsion will leak and accumulate in large quantities throughout the year, causing serious pollution of the equipment and the environment. Employees working in such an environment for a long time, grabbing parts soaked in lubricating fluid with their hands, are potentially harmful to the human body. With the emulsion processing type, after the product is processed, a lot of cleaning work will be generated, which requires labor and energy for cleaning.
After the engraving and milling machine adopts micro-lubrication, the processing process is quasi-dry cutting, and the micro-lubrication system can provide an appropriate amount of lubricating oil according to the actual processing requirements. In the engraving machine’s milling process, the cutting tools are cooled, lubricated and removed according to the requirements of the processing steps. After processing, there is no leakage of lubricating fluid and no oil on the surface of the workpiece, thus reducing the cleaning work in the subsequent process, and at the same time, there is no need to dry after processing. Doing secondary processing saves manpower and material resources.
The micro-lubrication system is powered by compressed air, and the oil mist consumption can be automatically adjusted according to the processing requirements, thus avoiding the waste of oil. The micron-level oil mist particles produced by the system are little affected by the high-speed rotating centrifugal force, making the oil mist more penetrating, reaching the lubrication point quickly, and making the use of lubricating oil more effective. Compared with the spray lubrication method of hydraulic station, it saves the huge lubrication station system and waste liquid treatment link, at the same time, there is no oil leakage, the equipment and ground environment are clean, and zero pollution is realized.
