■ Product Advantages
Robust Sustained Cutting Power (3.7kW)
The power is ample, showing a significant increase over 2.2kW. It easily drives larger diameter tools, supports higher feed rates and cutting depths, and greatly increases the machining efficiency for medium-hardness materials (like wood, acrylic, and aluminum).
Excellent Temperature Control and Precision
The water circulation cooling system efficiently removes heat from inside the spindle, ensuring an extremely low temperature rise even during long periods of continuous, high-load operation (typically 24,000 RPM). Stable temperature guarantees the spindle's thermal stability and long-term operational accuracy, which is key to achieving high surface finish in precision machining.
Extremely Low Operating Noise
Adopting a water-cooled structure completely eliminates fan noise. It runs significantly quieter than air-cooled spindles of the same power. This provides a quiet and comfortable working environment for operators, suitable for indoor or noise-sensitive locations.
High Reliability and Durability
The water cooling system effectively isolates the spindle's interior from contamination by external dust and debris, enhancing the spindle's overall reliability and service life in harsh industrial environments.
High Surface Finish Capability for Fine Machining
The stable temperature control and high design precision allow the spindle to be used for highly demanding finishing tasks, capable of achieving excellent processed surface finish and detail accuracy.
■ Application Scenarios

■ 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.
