■ Product Advantages
Robust Mid-to-High Power (2.2kW)
Provides ample cutting torque and power, capable of easily driving medium-to-large diameter tools and supporting higher feed rates and cutting depths. This significantly boosts the machining efficiency for materials like wood, plastics, acrylic, and aluminum alloys.
Excellent Temperature Rise Control
The water circulation cooling system efficiently removes heat from inside the spindle, maintaining an extremely low temperature rise even during long periods of continuous, high-load operation (e.g., 24,000 RPM). Stable temperature is key to ensuring the spindle's long-term operational accuracy and bearing longevity.
Extremely Low Operating Noise
Adopting a water-cooled structure eliminates the need for forced fan cooling, thereby eliminating wind noise. It runs significantly quieter than air-cooled spindles of the same power. This greatly improves the working environment for operators and is suitable for indoor or noise-sensitive locations.
High Precision and High Surface Finish
Stable temperature control combined with its design accuracy allows the spindle to be used for demanding finishing tasks, capable of achieving excellent processed surface finish and detail precision.
High Structural Reliability
The water-cooling system effectively isolates the spindle's interior from external environmental contamination (such as dust and wood chips), enhancing the spindle's overall reliability in harsh working environments.
■ Application Scenarios
High-Efficiency Wood Engraving and Routing
Applicable to deep routing, fine carving, and slotting in areas such as mahogany furniture, wooden doors, and large wooden crafts, balancing speed and precision.
Heavy Processing in the Advertising Industry
Used for fast cutting, polishing, and complex 3D shaping of materials like thick acrylic, PVC, and double-color boards.
Small-to-Medium Precision Mold Manufacturing
Performing high-precision, medium-volume milling and finishing of wax molds, resin, artificial wood, and certain soft metals (like copper and aluminum).

Customized machines for fine, automated production of small-to-medium-sized products.
■ 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.
