Technical Highlights: Hydrostatic-Enhanced Torque‑Multiplying Module for Spiral Bevel Gear Machining
This torque‑multiplying tool module is designed specifically for spiral bevel gear machining, combining a compact planetary reduction mechanism with our hydrostatic spindle technology. The result is a high‑torque, ultra‑stable cutting module that enables precise gear machining even on machines not originally built for this process.
Unlike conventional tool holders, this module integrates a planetary reduction system that increases output torque while maintaining smooth, low‑vibration motion. When paired with our hydrostatic spindle head, the system gains exceptional rigidity, thermal stability, and long‑term accuracy—ideal for the continuous curved‑surface cutting required in spiral bevel gears.
One of the key advantages is that this module allows a standard 5‑axis machining center to be instantly upgraded into a dedicated spiral bevel gear machining platform. This dramatically reduces the need for specialized gear‑cutting machines and shortens the adoption time for manufacturers entering the gear‑processing field.
By utilizing a Tri‑Cone interface, the hydrostatic system can be extended into various machining configurations, supporting turning, milling, grinding, and gear‑forming applications with high repeatability and structural stiffness.
Advantages of the Integrated Shaper‑Axis Module
Hydrostatic Support × Direct‑Drive Motor × Double‑Curved Cam Architecture
Our shaper‑axis module compresses the entire gear‑shaping mechanism into a compact, self‑contained unit, enabling high‑precision gear cutting without the need for a dedicated shaping machine. At its core is a hydrostatic bearing system that provides exceptional rigidity, zero mechanical wear, and stable performance under high‑frequency reciprocating loads.
Replacing the traditional worm‑gear mechanism, the module utilizes a Direct‑Drive (DD) motor, eliminating backlash and mechanical transmission losses. This allows for highly responsive, high‑accuracy motion control—critical for the precise in‑and‑out cutting action required in gear shaping.
Inside the module, a double‑curved cam mechanism generates a smooth, high‑acceleration reciprocating motion within a very short stroke. Combined with the hydrostatic oil‑film support, the system maintains dynamic accuracy even under heavy cutting forces, improving surface finish, tooth‑form fidelity, and tool life.
By integrating hydrostatic support, DD‑motor actuation, and cam‑driven motion into a single module, the shaper‑axis can be mounted directly onto a 5‑axis or multi‑process machining center, instantly giving standard equipment the capability to perform precision gear shaping. This modular approach dramatically expands the machine’s application range while maintaining the stability and performance of a dedicated gear‑shaping platform.
Key features of the external cyclone milling module (hydrastatic workpiece spindle × hydrastatic tool spindle × cyclone milling module)
Our external Whirling Milling Module transforms an ordinary machining center into a dedicated high‑precision thread and gear‑form machining platform. By combining a hydrostatic workpiece spindle, a hydrostatic tool spindle, and a compact bolt‑on whirling module, the system delivers exceptional rigidity, ultra‑low vibration, and long‑term accuracy that conventional mechanical structures cannot match.
The hydrostatic workpiece spindle provides a perfectly stable rotational foundation, while the hydrostatic tool spindle ensures smooth, chatter‑free high‑speed cutting. When paired with the whirling module, the system achieves high‑efficiency form milling with outstanding tooth‑profile accuracy—even on machines not originally designed for this process.
Because the module is fully external and self‑contained, any standard 5‑axis or multi‑process machine can be instantly upgraded to perform precision whirling operations. This eliminates the need for specialized equipment and dramatically reduces investment cost and lead time.
For applications requiring even higher accuracy, the same hydrostatic tool spindle can directly mount a grinding wheel, enabling post‑grind finishing to achieve superior surface quality and micron‑level form accuracy. This dual‑capability design allows manufacturers to complete roughing and finishing on the same platform, maximizing throughput and minimizing setup error.
In short, the hydrostatic + whirling module architecture delivers the performance of a dedicated machine—
but with the flexibility, modularity, and cost efficiency of an add‑on system.
Mountain System redefines precision manufacturing through hydrostatic technology and modular architecture. Any standard machine can be instantly upgraded into a dedicated gear‑machining platform—without sacrificing flexibility, accuracy, or long‑term stability.
