Just wondering if anyone is using these? I am considering my options at the moment, I am routing upto 1.5mm thick aluminium sheet at high spindle speeds with 1.5mm to 3mm cutters and I currently use a moderate amount of flood coolant, manually applied, which is obviously not the best solution. I am looking at the vortex air guns/tubes as my primary chioce of coolant, but do not have an air-compressor, so this must be added to the cost. I have no idea what size tube I am looking for, I have seen them from 2CFM to 15CFM, so what is the minimum size I would need? The second choice for coolant is a trico micro-drop system, which again, I need a compressor for, so what's the minimum size for this? Space in my "workshop" (read shed) is at a premium and noise levels should be low enough to stop nosey neighbours from coming around, hence all the questions. If I had the space I would buy big, but I don't. Oh yeah, perhaps someone could point me in the direction of a website that would give details on the amounts of heat generated by machining? Thanks guys!  |
