Characteristics of external and internal cylindrical grinders

1. External cylindrical grinding machines and grinding machines generally use bearing seat assemblies, which consist of three sets of five parts. Ceramic tiles are our common name. It should be called sliding bearing and power bearing. Due to the large size of the grinding wheel dynamic pressure spindle transmission, the main structure used is the bearing shell. If roller bearings are used, ripples will be generated and the workpiece problem will be small. Large grinding machines or larger load-bearing dynamic pressure spindles require a static pressure bearing, and the structure consists of static pressure bearings and dynamic pressure bearings, but I haven't seen it yet, I just heard from colleagues. I will repeat the difference between fluid dynamic bearings and hydrostatic bearings later. Dynamic bearings are a type of starting type bearing with high friction, and the radial resistance of dynamic and static bearings is relatively high after normal operation. Therefore, there are high requirements for the gap and distribution of contact points between the bearing and the tile, which requires maintenance personnel to carefully scrape the bearing. In post-processing, it is also necessary to understand the machining process in order to produce highly accurate dynamic pressure spindles for people to use. Due to various reasons, we are unable to disclose too much about the process

2. Internal cylindrical grinder, the dynamic pressure spindle of this grinder is generally a roller bearing structure. Due to the small size of the grinding wheel, the operating load is relatively small, and the operating speed is relatively high, it is not suitable for dynamic and static pressure structures. At the same time, due to the high speed, generally between thousands and 2000rpm, there are clear requirements for bearings and lubricating grease

3: Surface grinder, the dynamic pressure spindle structure of the grinder is more important. The pressure and static pressure are the same, only the length of the shaft. Various bearings are used for front and rear, and ceramic tiles have very different shapes, such as brick shape, cross-sectional shape, pipe shape, fan shape, and the first three

are combinations of surface grinder rotors!

The length of the front three and rear three axes of the roller is different, and the shape of the tube is different from that of a single cone tube and a double cone tube, depending on the shape of the grinder
