The dynamic and static pressure spindle of a surface grinder has significant advantages, mainly reflected in high precision, high efficiency, heavy load and heavy cutting ability, long life, high stiffness, and a wide range of applications. The following is a detailed explanation of these advantages:
1. High precision
Static pressure bearing oil film: The dynamic static pressure spindle of the surface grinder can achieve static pressure bearing oil film, keeping the spindle balanced at high precision. This balance state ensures the machining accuracy and surface quality of the workpiece, meeting the requirements of high-precision machining.
Rotation accuracy: Through the action of pressure oil film, the precision of spindle rotation can be higher than that of journal and bearing, further improving machining accuracy.
2. High efficiency
Large unit bearing capacity: The dynamic and static pressure spindle can provide a larger unit bearing capacity, which means that under the same processing conditions, it can withstand greater loads, thereby improving production efficiency.
Reduce friction: When the dynamic and static pressure spindle is in operation, the spindle will be lifted by a layer of pressure oil film, reducing friction between machines, lowering energy consumption, and ensuring smooth operation.
3. Heavy load and heavy cutting capability
High load-bearing capacity: The dynamic and static pressure spindle has excellent wear and tear adaptability and ultra-high load-bearing capacity, which can meet machining needs such as heavy loads and heavy cutting. This ability makes surface grinders more adept at processing large and heavy workpieces.
4. Long lifespan
Reduce wear: The structural characteristics of the dynamic and static pressure spindle include the combination of dynamic pressure oil wedges, static pressure oil chambers, and deep and shallow oil chambers, which effectively reduce wear and extend the service life of the spindle.
Non wear: As a non wear spindle supported by a dynamic and static pressure oil film, the dynamic and static pressure spindle can theoretically achieve non wear operation, further improving its service life.
5. High stiffness
Oil film stiffness: During the operation of the dynamic and static spindle, the oil film stiffness is the stiffness of the static pressure bearing plus the dynamic pressure bearing, which has strong load-bearing capacity. This high stiffness ensures stability and accuracy during the machining process.
6. Wide range of applications
Multiple material processing: The dynamic and static pressure spindle can be used for precision processing of various materials, such as metals, plastics, ceramics, etc.
Multiple machine tool applications: It can be used not only for external and internal grinding machines, but also for surface grinding machines, roll grinding machines, precision boring machines, diamond boring machines, and other precision rotary machinery, and has achieved good results in use.
In summary, the dynamic and static pressure spindle of the surface grinder plays an important role in the field of mechanical processing due to its advantages of high precision, high efficiency, heavy load and heavy cutting ability, long life, high stiffness, and wide application range.
