If bead blasting might work, you may want to consider vibratory finishing. Here is a link with an overview: http://www.kramerindustriesonline.com/vibratory-finishing-systems.htm I kind of like the idea of dumping a load of parts, turn the machine on and go away for a while. It may not be that easy though.

Re: [Emc-users] Surface Finsishing
Thanks to Dave, John & Wayne for the responses. It was helpful. A good option would be to fit a sander on the CNC machine. That will considerably speed things up.

I think he uses belts like this 47505A444 from mcmaster carr, a simple phone call would confirm the usage with them. and here is the Aluminum Polishing 101 pdf http://www.home-machine-shop.com/Down-Load/Polishing_Aluminum.pdf John On 3 Dec 2008 at 7:51, [EMAIL PROTECTED] wrote: > This would be nice if the belts could be for aluminum but I could > not > find any. > "http://www.thefind.com/hardware/browse-jet-aluminum-sander"; > > > > John Thornton wrote: > > You can get special belts for a sander that polish aluminum... the > finish depends on the > > grade... they look like 3-m polishing pads but on a belt... > > > > John > > > > On 2 Dec 2008 at 22:51, [EMAIL PROTECTED] wrote: > > > > > >> What do you guys use as the quickest and best cost effective > and > >> time-effective way to finish flat surfaces before the parts are > >> Anodized? > >> The parts are 8"x6"x3" Al boxes made from square tube with a > few > >> slots > >> and holes CNC'd in so the surfaces are still the raw surfaces. > >> I can CNC the boxes with a flat-face-mill , but wonder if there > >> isnt > >> something else you know of that is maybe a bit faster as I need > to > >> clamp > >> and turn each side for the mill if I want to do it that way. > >> > >> > >> > >> > >> > > >> - > >> This SF.Net email is sponsored by the Moblin Your Move > Developer's > >> challenge > >> Build the coolest Linux based applications with Moblin SDK & > win > >> great prizes > >> Grand prize is a trip for two to an Open Source event anywhere > in > >> the world > >> http://moblin-contest.org/redirect.php?banner_id=100&url=/ > >> ___ > >> Emc-users mailing list > >> Emc-users@lists.sourceforge.net > >> https://lists.sourceforge.net/lists/listinfo/emc-users > >> > >> > > > > > > > > > > - > > This SF.Net email is sponsored by the Moblin Your Move Developer's > challenge > > Build the coolest Linux based applications with Moblin SDK & win > great prizes > > Grand prize is a trip for two to an Open Source event anywhere in > the world > > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > > ___ > > Emc-users mailing list > > Emc-users@lists.sourceforge.net > > https://lists.sourceforge.net/lists/listinfo/emc-users > > > > > > > > > > - > This SF.Net email is sponsored by the Moblin Your Move Developer's > challenge > Build the coolest Linux based applications with Moblin SDK & win > great prizes > Grand prize is a trip for two to an Open Source event anywhere in > the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > ___ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Surface Finsishing
These sites deal with the finishing and polishing of Aluminum http://www.car-accessories-magazine.com/aluminum-polishing.html http://www.irinfo.com/polish/html/polish.html A Scotch-Brite™ Cut and Polish Flap Brush in a hand held drill would work. I could also see using a small round abrasive pad with a foam backer in the spindle of your mill and run a small G code program that moves the work piece approximately 3/4 the diameter of the pad and then lowering the head to just contact the work surface and repeat this the full length of the part resulting in the traditional circle polishing affect common on aluminum.

This would be nice if the belts could be for aluminum but I could not find any.

Re: [Emc-users] Surface Finsishing
You can get special belts for a sander that polish aluminum... the finish depends on the grade... they look like 3-m polishing pads but on a belt...

If you have a bunch of them to do then rig an A or B rotary axis ( probably with tailstock). It could even be hand indexed and locked in place. Some people would polish each face on a abrasive flat belt and be done with them. It depends on how much precision you need. Good Luck.

[Emc-users] Surface Finsishing
What do you guys use as the quickest and best cost effective and time-effective way to finish flat surfaces before the parts are Anodized? The parts are 8"x6"x3" Al boxes made from square tube with a few slots and holes CNC'd in so the surfaces are still the raw surfaces. I can CNC the boxes with a flat-face-mill , but wonder if there isnt something else you know of that is maybe a bit faster as I need to clamp and turn each side for the mill if I want to do it that way. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
