The main functions of the dynamic and static pressure spindle are reflected in the following aspects:
Improving machining accuracy: The dynamic and static pressure spindle establishes a static pressure bearing oil film inside the bearing, which keeps the spindle suspended in the high-pressure oil film from start to stop, avoiding mechanical wear and ensuring high rotational accuracy and oil film stiffness of the spindle. This design helps to restore the machining accuracy and surface roughness lost due to wear of the machine tool spindle, significantly improving machining quality.
Extended service life: Due to the non-contact operation mode of the dynamic and static pressure spindle, there is no direct friction between the spindle and the bearing, and the wear is significantly reduced, thereby extending the service life of the spindle. At the same time, using temperature controlled oil can also cool and lubricate the spindle, further eliminating thermal deformation and improving the stability and lifespan of the spindle.
Enhanced Load Capacity: The dynamic and static pressure main shaft combines the advantages of dynamic and static pressure bearings. Through the design of integral bearings and shallow oil chamber bearings, a dynamic pressure sliding bearing effect is formed when the main shaft rotates, improving the bearing's load capacity. This design enables the dynamic hydrostatic spindle to withstand greater radial and axial loads, making it suitable for heavy cutting and high-power machining applications.
Adapt to low-speed operation: The dynamic and static pressure spindle can also form effective oil film support at extremely low speeds, ensuring the stability and accuracy of the spindle during low-speed operation. This characteristic gives the dynamic hydrostatic spindle significant advantages in situations where low-speed high-precision machining is required.
Improving machining efficiency: The dynamic and static pressure spindle converts the hard friction between the spindle and the bearing into liquid floating rotation through high-speed rotating tools, achieving high-speed and efficient machining. Meanwhile, its high precision and low vibration characteristics also contribute to improving the quality of the processed surface, reducing subsequent processing steps, and thus enhancing overall processing efficiency.
Wide applicability: The dynamic and static pressure spindle is not only suitable for traditional machine tools such as external and internal grinders, but also has achieved good application results in precision rotary machinery such as surface grinders, roll grinders, precision boring machines, and diamond boring heads. Its diverse application scenarios make the dynamic and static pressure spindle an indispensable and important component in modern machining technology.
