Abstract

This research describes the study of HSA efficiency as a result of recycling used swage ball. Key Parameter Output Variables (KPOVs) of HSA which consists of gram load, arm height, swage torque and resonance were investigated using statistical methodology. Moreover, changes in physical characteristics of swage ball after swaging process were also examined. The results of the analysis showed that only swage ball having a big diameter underwent a physical characteristic change, i.e., ball roundness was decreased. However, KPOVs of HSA using those swage balls were not altered. The resonance of HSA is slightly increased, but the discrepancy is in the range of HDD servo stability margin. The results obtained could be used as guideline for the decision to implement used swage ball in head stack swaging process.
