Hi all,
We have a small CNC machine shop, working mostly with aluminum, stainless steel and some plastics, and I've been thinking lately about what sort of ventilation we should have in the shop.
We've got three machines:
1. A small turning centre, that has a port to attach ducting for air removal, but we haven't hooked anything up to it yet. It is pretty unpleasant though, when you open the door on it after it has been doing a lot of work; the air is hot and smelly (maybe coolant smell more that metal?).
2. An enclosed horizontal mill. We're just getting this machine up and running, so we haven't done much work on it yet. I wonder if its going to smell too after running?
3. A vertical mill where the entire top is open and exposed. Never noticed too much smell coming from it, but that just means the air is getting mixed well with the rest of the shop...
I wonder if we should be doing more about the air quality in the shop and if I should be more concerned about the long term effects. So I put the question out to all of you:
What sort of ventilation, or air removal systems do you have in place in your shops and what are your thoughts on the hazards of the air quality associated with metal machining?
Very curious to hear peoples responses.
