Hi Viesturs, If you are mainly planning on cutting aluminum I would suggest looking into oil mist cooling instead of flood coolant. You only need a trace of oil in the mist to act as a lubricant while the air clears the chips and cools the part. It works very well. You can get vegetable based oils specifically designed for this job that are relatively safe (you don't want to breathe mineral oil mist). The oil is expensive but lasts a long time as you only use a tiny amount. The parts come off the machine with just a thin film of oil on them. The trick is to use a nozzle that produces a fine stream of droplets rather than an atomized mist. The biggest disadvantage of this arrangement is that it is very directional so if you are cutting fairly deep you may need two nozzles. You can also use oil mist on steel with carbide cutters but smoke can be a problem.
I made my own up but you can buy oil mist sprayers e.g <http://www.fogbuster.com/> though they are a bit pricy. Les On 29/06/2012 07:05, Viesturs Lācis wrote: > Does anyone have something to suggest?
