what that means for the motors, roller guides, and ball screws.
Rust, more rust, and yet more rust, IF they get wet.
I use a 'water bath' with very high sides. Water pours in over the cutter and drains out the bottom. If I get it right than there is no water anywhere near the table or the rails. There were a few hiccups at the start, quickly fixed.
I did expect a huge amount of spray from the spinning cutter. In fact, while there was of course some spray out sideways if the cutter was exposed, it was not that bad, and it did not fly UP in the air. So high side-walls on the bath were enough. If the cutter is submerged, there may be no spray.
Here the cutter is not 'exposed' so there is no spray. I was drilling 1 mm holes in ruby balls to make touch probe stylii. Buying drilled balls was very $$$. The tricky bit is that the ball mount has to be spring-loaded with no wobble, so the 1 mm diamond drill does not wander and is not scrunched. Drilling ruby is slow. The white ring you can see in the water is ruby dust!
Here the cutter is exposed, but I have high sidewalls, some of them clear so I can see what the machine is doing. This is basalt. The hardest bit is sealing off the shaft from the rotary table and counter-headstock: baffles and slingers work. The basalt dust collects at the bottom: a real sludge.
