Preloading of high speed abrasive rolling bearings
In order to ensure the precision and surface roughness of the machined parts that cannot be achieved in the process of turning, milling and planing, it is necessary to ensure that the grinding machine has high rotation precision, good vibration resistance and sufficient rigidity (of course affecting grinding) There are many factors of precision, only the abrasive parts are discussed here. The rotation accuracy of the hemp is mainly reflected by the bearing rotation accuracy. The accuracy of the rotation of the uranium bearing is dependent on the accuracy of the bearing itself and sufficient lubrication and cooling during the rotation process. But experience tells us that to ensure the rotation accuracy of the bearing, the above conditions are far from enough, and there is a key factor that is often easy to be ignored - the preload of the bearing is correctly applied. That is to say, in the maintenance process, if the preload is applied to the book, the grinding can be guaranteed to have a good
