Re: Are there any reasons NOT to use flood cooling?

Gary,

A few reasons...

1. It'll make a mess of your surrounding area if you don't have full
enclosure around your machine. Few hobby machines are enclosed.

2. Quite a few of the coolants on the market contain hazardous
materials, chlorine being one of the most common. Makes your chips,
floor sweepings and shop rags hazardous waste. This can be a very
big issue with production shops or any for-profit shop. Penalties
for illegal disposal are harsh.

3. Coolants cause dermatitis for some people. Coolants can saturate
your work clothes, questionable health benefits of wearing those
clothes.

4. Coolants can get rancid and smell. For this reason some coolants
contain antibiotics, exposure to antibiotics is questionable.

5. Some parts can't have coolant used on them because of porosity
and contamination issues. Also, value of chips is higher for non-
coolant, dry chips.

6. Probably lots more reasons that don't come to mind right now.


For the above reasons and more, an emerging trend in high production
machining is toward dry machining. The trade mags of late are full
of articles about dry machining.
