Hi,
The cooling water of my 2,2 Kw spindle is turning dirty brown rather quick. I've been using plane water and the spindle is made in China. Should i use any additive to avoid rust? Or is this oil / grease dissolving in the water? Do I need to lubricate the spindle regularly? I have not used the machine for a month or 2 in summer and did not remove the cooling water in that period. I thought the brown durt would wash out after refreshing the water a couplde of times but it still seems to get dirty again after a couple of hours of milling. The spindle runs fine, and remains cool, no strange noises. Should i worry?

Thanx

You should be running some corrosion inhibitor in the water. Automotive anti-freeze mixed 50/50 should work well.

Yeah. Anti-freeze or coolant is already engineered to basically do the same job in a vehicle.

Tormach sells a lubricant/corrosion inhibitor for your cooling loop:

35553 - Water Chiller Treatment, 8 oz.

Hi guys, thanx for your advise.
How stupid can I be. If been using this additive in my manual mil for years. But in the enthusiasm of getting my CNC started I just forgot about it.
I guess the best would be to dismantle and clean the whole spindle and then start running with the additive.
