Does anyone have suggestions for making a CNC mill that's quiet enough to run in my apartment? I'm thinking about getting one of the cheap $250 Aliexpress specials (I only want to mill PCBs), but I'm guessing it's going to be too loud to run in a building where other people live. If I can make some performance tradeoff for relative quietness, I'd love to do it.
(Maybe it's as simple as putting it in a foam enclosure or something? That sounds bad for spindle cooling, though.)
- kedikedi 5y agoSound is one thing but also think of the dust, especially if you’re planning to machine pcb at your home. That’s not good stuff. But speaking of sound, some of it comes from the spindle. The faster it turns, the more noise it makes (usually). I was using a dremel as my spindle some time ago and it was veery noisy. Then I tried another machine that had a bigger spindle, that one was much quieter. Then there’s the sound of the material being processed. The cutting bit hits the material at spindle_speed*flute_count Hz. This also creates hell of a vibration. So you need to do two things: dampen the vibrations, and block the radiated noise. Plus you want to make sure you have some sort of dust control.
- jrockway 5y agoThat's a good point; the cutting itself is going to be noisy. I will have to rethink this project.
