Just a general report. We probably need a tag on the nozzle that says for metal use only or something along those lines.
It works great for clearing chips. One of the cuts I did was a long slot that normally gets bogged down with chips and required constant hand clearing. No more. No recutting of chips, it just worked. It kept the part cool when doing some roughing work as well.
The only drawback is the air is rather wet. And that’s both a good thing for cooling, but also bad because of water and electronics and the spoilboard. The regulator spits out enough water that over a short period of time it’ll start dripping. This is easily controlled however by stuffing a paper towel under the regulator, replacing it every hour or so as it gets saturated. On the other hand, it’s nice and cool air.
It does make a bit of a mess though, I have to spend extra time cleaning, but I think it’s worth the trade off to have it. I sweep the bed with a broom and then use compressed air to clear off any remaining fine metal. (There’s no sawdust), followed by a thorough sweeping of the area. If the shark cnc was moved, it’s make cleaning that side a bit easier. I found chips about 6’ away from the bed, and my part was on the far side of the bed. I’ll just plan some extra cleanup time when I schedule time.
Overall I’m going to make good use of it, the extra time I spend cleaning is saved by not having to replace endmills as often and not having to babysit several sections to do chip clearing. My (cheap) endmills are staying sharper longer.
The nail gun is giving me fits. I look forward to the new line coming in, so we can run it on lower pressure.
