Ultra-precision Turning Technology of Gold Cone in Fast Ignition

摘要：

　　Fast Ignition (FI) attracts much attention owing to its advantages.The fabrication of fast ignition targets is one of the key technologies in FI study.Based on the single point diamond turning (SPDT) technology,Diamond post-turning method is adopted in this paper for the fabrication of gold cone.It not only helps to reduce the end-effect of cone mandrel and consequently improve the coaxiality of internal and external cone surface,but also helps to improve the quality of cone surface and the wall thickness consistency.Besides,the processing parameter of diamond post-turning is experimentally studied in this paper for its effect on the cone surface roughness.According to results,the cone surface roughness is Ra 9.21nm,the wall thickness consistency is 3μm and the cone end surface roughness is Ra5.72nm.
