Milling in a water bath works exactly the same way as conventional milling, and you have to select your parameters the same way for both methods. However, there are a couple of things you have to watch out for when milling under water:
The tool mustn’t touch the sides or the bottom of the water bath. The sides
of the water bath limit the maneuvering space of the spindle, and the ma-
chine can only reach all points on the machine table when it is positioned
above the level of the sides of the water bath. When positioning the tool, always adjust the Z position last.
Make sure that there is sufficient space between the surface of the water and the spindle so that the water can’t splash onto the machine. This makes it less advisable to insert the tool shank as far into the collect as possible, as you would in a conventional milling situation. The total plunge depth is increased by the depth of the water above the workpiece plus your safety margin. This inevitably causes a loss of rigidity in the spindle/tool assembly and leads to increased vibration.
When milling under water, use only a machine with appropriate IP protection certification and a surge protector, or use a low-voltage machine. The illus tration  in the following sections are for demonstration purposes only, as our machine doesn’t have an appropriate HF spindle. Never use a normal AC110V hobby-grade spindle for underwater milling.
