I like the idea of the brush for a curtain Still provides access to
the collet for easy tool changes; the bristles would probably help
loosen some of the compacted dust that forms behind the tool when I'm
machining FR4 PCB material as well.
I would be happy to see any photo's you may have.
- I just posted a picture of Roland's vacuum attachment for a PNC-3000.
This vacuum attachment measures 7 3/4" long x 4 3/8" wide
Inside diameter around the spindle area is 3" inside x 1 1/2" tall.
A 1 1/4" diameter tube pulls from the spindle. Tube is 4" long.
A soft bristle brush fits over the 3" cylinder to pull chips away from
your work. Makes changing the end mill in the collet a little harder
Hope this helps if you are trying to make your own version.
