### **Core Product Advantages**
**Micron-level Motion Control**
- Servo hydraulic drive, positioning accuracy ±0.005mm (closed-loop feedback)
- Pressure fluctuation < ±0.3% FS, ensuring constant cutting force
- Ultra-low speed stability (0.1mm/min without crawling phenomenon)
**Intelligent Energy-saving Design**
- Variable-frequency pump set + accumulator combination, energy saving by over 40% (verified data)
- Demand-based oil supply technology, flow automatically reduces to 10% when no load
- Thermal energy recovery module (optional), reduces the load of the machine tool cooling system
**Integrated Machine Tool Optimization**
- Ultra-thin Hydraulic Station design (height < 500mm), facilitating installation at the bottom of the machine tool
- Vibration value < 0.5mm/s (in accordance with ISO 10816-3 standard)
- Modular quick-disassembly structure, reducing maintenance time by 70%
