Innovation and application fields of dynamic and static pressure spindle technology

The technological innovation of the dynamic and static compression spindle is mainly reflected in the following aspects:

1 Ultra high speed machining: The dynamic and static pressure spindle forms a static pressure bearing oil film by injecting constant pressure oil, forming a combination of dynamic pressure oil wedge, static pressure oil chamber, and deep and shallow oil chamber, which has the ability to adapt to low-speed heavy-duty machining and ultra high speed operation

2. Pre tightening force switching: The dynamic and static pressure spindle has the function of automatically switching pre tightening force, ensuring stability and accuracy under high-speed operation, greatly improving machining efficiency

3. Replacement and filtration of No.2 spindle oil: The dynamic and static pressure spindles need to be regularly replaced with No.2 spindle oil and coarse and fine filter elements to ensure their normal operation

4. Loading and unloading of pulleys and grinding wheels: The dynamic and static pressure spindle needs to load and unload pulleys and grinding wheels during the operation of the pump station to ensure the stability of its working state

5. Technical maintenance and upkeep: When the dynamic and static pressure spindle operates at higher speeds, it can provide higher machining efficiency, but requires higher technical maintenance and more frequent upkeep

6. Wide application fields: Dynamic and static pressure spindles are widely used in various fields, such as ultra high speed machining centers, fully automatic CNC bearing outer ring groove grinders, rolling bearing inner ring turning automatic lathes, etc
