Abstract
The scope of the document is report the tests performed to characterize the polishing process by means of 3M™ Trizact™ Hookit™ Film Disc 568XA and 3M™ Trizact™ Hookit™ Film Disc 268XA. The tests were part of the optimization of the polishing process, to increase the speed and to reduce the costs of shell production]. They were carried out on fused silica samples prepared with a starting micro-roughness of the order of 50 - 70 nm rms (equivalent to the initial status of the shell under manufacturing). We characterized the removal rate and the micro-roughness improvement rate in dependence of several parameters as amount of water, pH, velocity and pressure, taking care also of the wear rate of the pads.
