This document contains two case studies describing machined parts that were polished in preparation for chrome plating. The first case study describes a 1.25" diameter by 3" long brass coupling that was cut and polished to remove tooling marks and burrs. The second case study discusses alloy steel handgun slides measuring 1" by 1" by 8" that were polished using appropriate media to prepare the surfaces for plating by removing burrs and improving quality.
