Drawn, ground, and polished

From Wikipedia, the free encyclopedia
(Redirected from Drawn, Ground, and Polished)

Drawn, ground, and polished (DGP) is a classification of finishing processes often used for metal shafting. Cold drawing increases the metal's strength, while grinding and polishing improves the surface finish and roundness for high dimensional accuracy.[1][2][3]
