Proxxon mill noise.

[Maurice Cox 1Participant @mauricecox1]

I recently acquired a nearly new Proxxon milling machine from the estate of a deceased friend. When it is turned on, there is a lot of noise from the motor brushes/comutator. I mean A LOT. Is this common? How have others improved this; assuming that they had a similar problem. I was considering undercutting the insulation between the copper segments. We used to do this on some motor driven generators where I worked.

Here's a video clip of  MF70 in action…… how does the noise compare? Might be plenty more videio clips knocking about.
