Spindle bearings of CNC grinding machines use spindle bearings as the core components of CNC grinding machines, and their performance will directly affect the main parameters of CNC lathes such as rotation accuracy, speed ratio, stiffness, temperature rise and noise, and then endanger the production quality of product workpieces. Therefore, in order to maintain an excellent level of grinding machine processing, be sure to use high-performance bearings. 1. The precision of the bearing used in the spindle of the grinding machine should be above P5 level, and the precision of the rotary table bearing for fast and high-precision machines such as CNC grinding machines and CNC machining centers should be of P4 level or above. 2. CNC grinding machine spindle bearings include angular contact ball bearings, cylinders, tapered roller bearings, crossed tapered roller bearings, and crossed cylindrical roller bearings. As far as the interfacial tension of angular contact ball bearings is concerned, it is more popular at this stage to refer to the surface tension of 15o and 25o; generally, the surface tension of 15o has a relatively strong speed ratio performance, while the surface tension of 25o has a strong radial bearing capacity . 3. For crossed roller bearings without surface tension, a single set of bearings can meet the needs of radial and axial loads. If necessary, the stronger rigidity can choose horizontal tapered roller bearings. Because the selection of preload is very harmful to the application of high-precision angular contact ball bearings. For example, in places with high load-bearing and high rigidity, medium-large or large-scale bearing preloads are generally selected; while for some high-speed rotating, high-precision ball bearings When using public places, you should pay attention to choosing the preload that suits you when selecting the initial model of the spindle bearing of the CNC grinding machine. Generally, light preload is more common. Preload is generally divided into three types: light, medium and small, and super heavy. Generally, light preload is more common. Only when the torque is accurate can the rotation be stable! (http://)
