FAQ

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