Structure and Maintenance of Grinding Machine Dynamic Pressure Spindle

In terms of equipment maintenance, the technical level of grinding head maintenance can be said to be the highest. Why? Due to the high precision, mechanical strength, and stability requirements of the grinding machine dynamic pressure spindle, the maintenance of the grinding machine dynamic pressure spindle also faces great risks, and the maintenance technology is generally not transferable. If there is a slight mistake, the newly repaired dynamic pressure spindle may get stuck on the tile, causing maintenance accidents and damage to the new equipment. Therefore, in order to meet these requirements, maintenance personnel need to have a high level of technical proficiency, a good mentality, and patient debugging<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. In addition, the dynamic balance of the dynamic pressure spindle is also very important. Whatever conditions permit, it can be done to the best of its ability, so that the dynamic pressure spindle in use can be precision machined and perform well
