AI Technical Summary
Existing CNC machine tool frames lack transverse and oblique buffer structures, which cannot effectively absorb multi-directional vibration energy, resulting in decreased machining accuracy and increased surface roughness.
A composite damping structure was designed, including a lateral buffer component, a vertical buffer spring, and an oblique buffer component. Through the synergistic effect of multiple levels and directions, it absorbs and dissipates vibration and impact energy, thus constructing an all-round damping system.
It significantly improves the vibration damping performance and stability of the machine tool frame, increases machining accuracy and equipment life, and prevents damage to the machine tool caused by vibration interference.
