Advice on Water Cooled Spindles

Postby LonePine » Tue Jun 10, 2014 1:39 pm

Hi,

I have a water cooled spindle on my CNC machine. Its relatively new. The manual for the spindle was 1 sheet of paper. It was written in chinese.

    Do I need to worry about rust?
    How do I keep algae from growing in the water?
    If I am not going to use the Spindle for 8 Weeks should I drain?
    Is there an additive that I need to put in the water?

Whats the deal?

Hi Lonepine,

Not to worry, its no big deal...

My cooling system is a 5 gal bucket with a submersible pump and lid to keep out trash.

I used distilled water with some food coloring so I can see it in the clear hoses....

No issues with rust or anything after 3 years, never changed or drained anything.

I have heard a touch of bleach in the water will stop anything from growing but I have not found it necessary.

Hope this helps....

you can purchase some radiator water for water cooled computers on amazon.

My set up is similar to one already described, 25 ltr barrel which contains a submersible pond pump, I have however added anti freeze to the water which will do all the things you mention & you can see when the pump is working. Gets quite cold in Scotland during winter so will also stop the cooling system freezing.
If your buying a pump make sure you buy one with a suitable head, my barrel/container sits under the machine so the water needs to be pumped up hill :D

I was thinking regular auto type antfreeze - but I don't have any experience with water cooled spindles. Wish I did.

That's what I use in my machine Leo, not had it for that long but has been ok so far. It was a post on another forum that I read about it.
