Technical Highlights of the Hydrostatic Spindle Head

Our hydrostatic spindle head is engineered around a proprietary hydrostatic bearing system that delivers exceptional rigidity, zero mechanical wear, and ultra‑low vibration. The spindle is fully supported by a pressurized oil film, allowing it to maintain geometric accuracy and dynamic stiffness even under high‑speed, heavy‑load machining conditions.

Designed for turning, milling, and grinding, the spindle head enables true multi‑process capability within a single platform. This not only simplifies machine integration but also ensures consistent precision across diverse machining operations.

When working with hard and brittle materials—including ceramics, quartz, and tungsten carbide—the hydrostatic support system absorbs vibration and cutting shock, preventing micro‑cracks, edge chipping, and thermal deformation. The result is superior surface finish, longer tool life, and significantly higher process stability compared with conventional bearing spindles.

Leveraging our advanced fluid‑dynamic modeling and structural optimization, the spindle achieves rotational speeds more than twice those of typical market modules. This performance advantage greatly enhances turning applications, enabling smoother high‑speed cutting, improved cycle times, and more flexible process planning.

We are also among the very few manufacturers capable of applying hydrostatic technology to a fully rotatable spindle head module. By integrating a tri‑cone (triangular cone) interface, the hydrostatic system can be extended to a wide range of machining configurations, enabling flexible module combinations and broader application coverage.
