■ Product Advantages
Excellent Temperature Rise Control
The water circulation system efficiently removes heat from inside the spindle, maintaining an extremely low temperature rise even during long periods of continuous, high-speed operation (typically 24,000 RPM). This directly guarantees bearing longevity and the spindle's long-term operational accuracy during work.
Extremely Low Operating Noise
Due to the water-cooled structure, no fan is needed for forced cooling, 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 noise-sensitive locations.
Ideal Medium-to-Light Cutting Power (1.5kW)
The power is moderate, sufficient to drive medium-diameter tools (such as 3.175mm or 6mm) for efficient milling, fine engraving, and drilling of wood, acrylic, plastic, and some light alloys.
High Speed and High Surface Finish
It possesses high-speed capability, and combined with stable temperature control, it allows the spindle to be used for high-speed cutting with small-diameter tools, achieving extremely high processed surface finish and detail precision.
High Structural Reliability
The water-cooling system effectively isolates the spindle's interior from contamination by external dust, wood chips, or debris, enhancing the spindle's overall reliability in harsh working environments.
■ Application Scenarios
Fine Wood Engraving
Applicable to high-precision, detail-rich relief carving and routing in fields such as mahogany, solid wood furniture, and wooden crafts.
Advertising and Signage Production
Used for precision cutting, polishing, and 3D shaping of materials like acrylic, PVC, and double-color boards.
Small Mold Manufacturing
Performing high-precision, low-material-removal milling and fine machining of wax molds, resin, artificial wood, and certain soft metals (like copper and aluminum).
Education and R&D Institutions
Suitable for college laboratories, maker spaces, and small prototyping environments where noise and precision are strictly regulated.
■ Adapted Equipment
● Small-to-Medium CNC Engraving Machines
General-purpose CNC equipment used for advertising, crafts, and small mold making.
● Small Precision Machining Centers
Machining equipment dedicated to high-precision parts, circuit boards, or precision molds.
● Multi-Head Engraving Machines
Used on equipment where multiple spindles must work simultaneously to boost efficiency, and where operating noise is a concern.
■ 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.
