Article Preview

A new way of precision machining was studied through the experiments of Electrolytic In-Process Dressing (ELID) precision grinding and ultra precision lapping and polishing for W-Mo metal alloy. First a 22nm(Ra) surface was obtained through the ELID grinding, last a 11nm(Ra) surface was obtained after the process of lapping and polishing with 0.1~0.3 N/cm2 pressure, 60~100 r/min rotational speed and other optimized parameters. Meanwhile, the formation mechanism of ultra precision mirror surface of the alloy was also analyzed. The experiments prove surface quality of the work piece was guaranteed by ELID grinding, and which was also greatly affected by some parameters in lapping and polishing such as pressure, rotational speed.
