A term for router heads on CNC-machining centres, which are cooled by means of a liquid.
In most cases, the cooling aggregate is installed outside the aggregates support, often as a separate unit in order to facilitate the smooth operation with large liquid volumes and surfaces.
Advantages in comparison with air cooling
- Far better cooling, resulting in better performance
- The router head can be designed more compact, for there aren't any outside cooling ribs or air channels to be integrated.
Desadvantages in comparison to air cooling
- Far more expensive than most air cooling systems
- Definitely more construction elements, which implies the increased risk of malfunction
- With leakage fluid, even a minor system fault can cause great damage.
