Turning and micro lubrication

The current cutting fluid lubrication cooling method is widely used in turning processing. Such lubrication causes relatively large physical injury and environmental impact to the operator and the workshop environment. The processing cost of cutting fluid is also relatively high. Due to the emergence of these problems, the application of micro-lubrication technology in lathes has been promoted. <br /> The amount of back-grabbing, feed, and cutting speed are the main factors that directly affect the quality and efficiency of turning. In order to improve the impact of cutting fluid on the machining environment and on the maintenance requirements of the lathe, it is important to study the application of micro-lubrication technology in lathe cutting. The advantages of micro-lubrication for lathes are: <br />

1. The design cost of the machine tool is reduced, and there is no need to focus on sealing protection, which saves costs. <br />

2. The cutting fluid cooling system is removed to reduce the floor space. <br />

3. It can improve the surface processing quality of the workpiece. <br />

4. Improve processing efficiency. <br /> There are two types of micro-lubrication devices for lathe cutting: oil mist lubrication devices and oil-air lubrication devices. Micro-lubrication is a lubrication method in which vegetable-based trace oil is atomized into micron-sized particles and then delivered to the tip of the knife through an external nozzle or through the internal cooling channel of the knife handle. Oil-air lubrication is a lubrication method in which a very small amount of lubricating oil is accurately metered and then delivered to the nozzle by compressed air. The compressed air is torn into mist particles and sprayed to the cutting part. Because of the low oil consumption, these two lubrication methods can be applied to the micro-lubrication machining of lathe cutting. <br /> Regardless of the lubrication method, compressed air is used as the power, so the pressure and stability of the compressed air directly affect the reliable operation of the lathe cutting micro-lubrication device. The air source pressure of the lathe cutting micro-lubrication system is ideally at 8-10bar. This pressure range can ensure the lubricating oil atomization rate and delivery volume. The response speed from opening the micro device to spraying to the tip of the knife is fast, and it almost arrives with the air source. It has good permeability while being reliable in delivery, which has a good lubrication effect and the effect of suppressing temperature rise. <br />
