■ Product Advantages
Robust Power for Fine Machining (2.2kW)
The power is ample, providing stable cutting torque and capable of driving medium-diameter tools while supporting higher feed rates. This allows the spindle to handle not only fine engraving but also medium-light milling and batch slotting, significantly boosting production efficiency.
High Precision and High Surface Finish
The 2.2kW spindle has high-speed capability (usually 24,000 RPM or higher). Its design accuracy, combined with an excellent temperature control system (water-cooled), ensures high detail precision and excellent surface finish during high-speed cutting.
Reliable Temperature Rise Control
Whether water-cooled or optimized air-cooled, the design focuses on controlling the spindle's temperature rise during long periods of continuous operation, ensuring thermal stability and bearing longevity. This is crucial for engraving factories requiring continuous work.
Wide Tool Compatibility
Capable of stably clamping tools ranging from very small to medium diameters, meeting diverse machining needs from large-volume roughing to micro-fine engraving.
Excellent Versatility
2.2kW is one of the most mainstream power configurations on the market, offering balanced performance and easy integration with various drivers and CNC systems.
■ Application Scenarios
Medium-to-Large Fine Wood Engraving
Applicable to high-efficiency, high-precision relief carving, routing, and slotting in areas such as mahogany furniture, wooden doors, and large artwork, balancing large-area processing with detail handling.
High-Demand Advertising Industry Processing

■ 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.
