Not to minimize your great contributions to chilling, does anyone think that one of these water coolers could be adapted? I have one that just sits here and wastes electricity most of the day. They claim
ice cold at approximately 47° F
I can’t find a spec on how quickly they can take the heat out or a duty cycle.
Darn, I made the effort to go and convert to Fahrenheit (which felt to me like using Google translate to Chinese), and yet my European subconscious took over and had to write “°C”
So it’s actually a cold garage, It’s not heated.
Those laser tubes, which are 10-15% efficient, can produce as much as 900 Watts of heat. A spindle would have to be cutting at 900 Watts to generate that much heat. That’s not possible on Shapeokos. So, at “room temperatures” either a CW3000 (“Passive Water Chiller”) or CW5000 (“Active Water Chiller”) should suffice.
It does have an alarm, but it goes off at 60°C / 140°F, so not so useful because I assume the spindle would have died before reaching that coolant temperature.
I also know that the other alarm (detecting the absence of coolant flow) works fine, I discovered that when I unintentionally pinched the tube and had a near heart-attack when it beeped (the alarm is LOUD, as it should be)
Hey that’s a good question, I never actually measured the spindle. But it’s quite different, it’s the sweet sweet sound of making chips, I crave that!
Seriously though, it’s more the sum of semi-loud devices that gets on my nerves (that @$*&#! VFD fan, the muffled sound of the vacuum under the enclosure, the chiller, and optionally the washing machine and dryer nearby)
By the way, I had a wild shower thought (literally) the other day, I could extend the cooling circuit to go through the VFD sink. Water-cooled VFD !
Yeah I know how it sounds (dangerous), but I wonder if I could just use a PC water-cooling [part that goes on the CPU] and attach it to the back of the humongous VFD sink. It would be away from the power area, and in the unlikely event of a leak, gravity would do its job and not soak the inside of the VFD.
Well with that said I’m surprised you haven’t re-wired your VFD fan to only come on when it heats up…
You are either mad or have too much time on your hands
I gave up on trying to cut the noise out. Now I just wear noise cancelling headphones - after you have a compressor, VFD and spindle going it’s the only way to win a loosing battle, other than locking everything in a cupboard…
I know the sounds are annoying but the human senses alert you to danger. When I sit on my big lawn mower it is tempting to listen to music but if my mower deck starts making a racket I need to stop it before too much damage is done. Same in the shop. Music is fine for sanding but when doing things where I can lose a finger the music is off and my attention is focused on the task.
I’ve got a 50l quiet compressor which runs about 60db. It helps but when chips are flying, VFD going, compressor cycling it’s never going to be pleasant. I will add that my machines are not in enclosures, with all the testing we’re doing it’s a pain to drag them in and out
