■ Product Advantages
Ultra-Strong Sustained Heavy Cutting Capability (7.5kW)
The power is in the ultra-large power segment, providing extremely high sustained torque and power reserve. It effortlessly drives large-diameter tools for high-speed, large-volume heavy cutting, which is crucial for achieving maximum industrial efficiency and material removal rate.
Ultimate Cutting Rigidity
The tapered tool holder interface makes close contact with the spindle face, providing top-tier radial and axial rigidity. This minimizes tool vibration and axial displacement during high-load, deep cutting, ensuring ultra-high machining accuracy and tool life.
Extremely Low Operating Noise and Temperature Control
The water circulation cooling system completely eliminates fan noise and efficiently controls the spindle temperature. Stable temperature guarantees the spindle's thermal stability and precision during long periods of continuous, super-heavy-load operation.
High Reliability and Durability
The water cooling system effectively isolates the spindle's interior from external dust and debris. Combined with the heavy-duty design of the tapered interface, this ensures the spindle's ultra-long service life in the harshest industrial environments.
■ Application Scenarios
Ultra-Heavy-Duty Mold Manufacturing and 5-Axis Machining
Used for large-volume, high-strength roughing and semi-finishing of large mold steel (light duty), artificial wood, and high-density foam molds, serving as the ultimate power for determining roughing efficiency.
Hard Material and Thick Panel Cutting
Used for extreme-speed cutting, high-precision milling, and complex 3D shaping of materials like thick acrylic, high-density PVC, and thick solid wood.
High-Precision, High-Load Automation Integration
Suitable for professional workstations with the strictest requirements for automation level, power, precision, and noise.

■ FAQ
Q: Why choose a water-cooled spindle?A: They have good heat dissipation, low noise, and high machining accuracy.
Q: What should be paid attention to in the daily maintenance of a water-cooled spindle?A: Use clean water (purified water), change the water regularly, and remember to use antifreeze in winter.
Q: How to choose the right power for a water-cooled spindle?A: 3.2kW and below: Suitable for engraving wood, plastic, and other materials.
5.5kW and above: Suitable for processing hard materials like metal and stone.
Q: Why does the spindle get hot?A: If the water isn't circulating (for example, if the pump is broken or the pipe is blocked), the spindle will overheat.
Q: What type of water is best for cooling?A: It's best to use purified or distilled water.
Q: How big should the water tank be for the cooling system?A: The bigger the water tank, the better the heat dissipation. A 10-20 liter tank is generally sufficient for a small spindle.
