With the rapid development of science and technology, more and more equipment has entered the factory, which not only improves the working efficiency of workers, but also increases the output. However, no matter what equipment is, we can not ignore its maintenance and maintenance. Lubrication is the most important. Today, I will talk about the role and selection of guide rail lubricating oil to help you better extend the service life and performance of the guide rail.
After the guide rail is lubricated, it can work as close to a liquid friction state as possible, which can reduce the friction resistance, thereby reducing the driving power and improving the production efficiency of the equipment? The existence of the lubricating oil of the guide rail can also reduce the wear and prevent the guide rail from being corroded. Meanwhile, the flowing lubricating oil can also play the role of washing away some impurities. The lubricating oil can avoid creeping phenomenon under low speed and heavy load, and reduce the vibration of the equipment. The lubricating oil can reduce the friction heat generated during high speed and reduce the thermal deformation of the guide rail.
Many people do not know how to choose the lubricating oil for machine tool guide. According to previous experience and data, the following factors should be considered when selecting the lubricating oil for machine tool guide.
According to the needs of different types of machine tool guide rails, the lubricating oil as the hydraulic medium can be selected, which can not only meet the needs of the guide rails, but also meet the needs of the hydraulic system. For example, similar to the coordinate boring machine, the viscosity of the guide rail oil should be higher. However, in the case of grinding machines, the guide rail lubricating oil is often supplied to the hydraulic system, so the requirements for the hydraulic system are relatively high, At this time, the viscosity of the guide rail hydraulic oil can be lower, that is, it can meet the viscosity required by the hydraulic system, and the viscosity of the lubricating oil can also be selected according to the sliding speed and average pressure of the guide rail. When selecting guide rail lubricating oil, you can refer to some practical examples.
The guide rail of CNC machine tool usually adopts centralized oil supply and automatic drip lubrication. The lubricating equipment is a thin oil centralized lubricating device. The device is composed of a quantitative lubricating pump, a precision oil filter for feeding the same oil, a liquid level detector, a feed oil detector, a pressure relay, a progressive oil separator and an oil tank. The guide rail surface shall be regularly and quantitatively supplied with oil.
Solid lubrication is to cover the solid lubricant on the friction surface of the guide rail to form a bonded solid lubrication film to reduce friction and wear. There are many kinds of solid lubricants. According to the basic raw materials, they can be divided into metals, metal compounds, inorganic substances and organic substances. Adding solid lubricant powder to lubricating grease can enhance or improve the bearing capacity, aging performance and high and low temperature performance of lubricating grease.
After reading the above contents, it is believed that all readers present have a certain understanding of the role of guide rail lubricating oil. I hope it can help you.
