Provide reliable lubrication adjustment For the electric spindle with oil-air lubrication, reliable lubrication conditions should be provided for the spindle. The lubricating oil injected into the oil-air lubricator needs to be filtered to avoid mixing of impurities and mixing of oil types. Regularly observe the amount of oil and add oil to avoid cutting off the oil. Keep the bearings clean. High-precision high-speed electric spindle bearings are an important guarantee for the rigidity and accuracy of the electric spindle. Cleanliness is very important for precision bearing products. The cleanliness of the bearings is an important part of ensuring the service life of high-speed electric spindles.

CNC machine tool CNC cylindrical grinder solves the problem of parts processing with complex shapes Mower Deck Spindle and high precision requirements, and satisfies large batches, high machining accuracy, and stable product quality. At present, my country's CNC machine tools have been developed from the times There have been many years of history. With the continuous improvement and advancement of electronic skills, computer skills, automatic control, fine measurement and other skills, the position of CNC machine tools in the machine manufacturing industry has shown strong advantages. The advantage of electric spindle lies in high-speed cutting and fast feed

As usual, there are three kinds of preload values ​​on the bearing samples. But when it is used in an electric spindle, it should be considered comprehensively based on the type of smooth oil and cooling. The selection principle is that the preload is only required, and the influence of external load on the preload is considered.

After taking the above measures, the rotation accuracy of the electro-spindle system is guaranteed, and the radial runout and end runout of the spindle are within. This lays the foundation for ensuring the machining accuracy of the workpiece.
