Supposing you want to work in an apartment, and you're not concerned about cost, power, etc... but do want to cut some foam to get used to your machine and the software... what is the most quiet cutting motor that you know of? Small or expensive is fine. A router makes a bit of noise, a dremel a bit less, is there something smaller that even more quiet?

Also, is there a reason that there aren't small servo-type motors used on CNC machines? I've seen them used on merrow machines in stead of electric motors to reduce noise, is there a reason no one uses them on CNC machines that are used in classrooms or apartments?

Thanks!

Servo motors are widely used on the 'bit more expensive' hobby machines. That being said, the quietest spindle I have is belt driven with a servo motor. Virtually no noise when it's running but not cutting.

Thanks Paul, was that a Wolfgang Engineering spindle or someone else's?

n2airz.... thanks, too. I have a K2 machine, and they actually offer a bracket for the Hitachi M12VC but as it's a router, even if it would be a quiet one, it's still a bit more noise than I was hoping for...

It's a spindle I made starting with the x2 mini mill spindle from little machine shop.

Here's a pic of before it was complete:

A chinese spindle will be the quietest option. But be aware that cutting noise can be louder than even a loud router.
