ASHING In the ashing process, the Chemcast® GP is
buffed with a slurry or paste of pumice abrasive and water. In
production operations, some fabricators have found this process
to be more economical than sanding and polishing. Several grades of ashing compounds are used
successively. Higher wheel speeds can be used when ashing than
when polishing, because the wet abrasive cools the work. Stitched
cotton buffs 10" to 12" in diameter are often driven at
1750 rpm. Since the part must be held very firmly against the
wheel, it is necessary to use twohorsepower motors. |
