Abstract
This paper describes the single point diamond turning technology (SPDT) for the micro-hole machining on glow discharge polymer (GDP) capsule. The fixing and locating method of GDP capsule is firstly studied, and the special fixture for GDP capsule is designed. The special diamond tool for the machining of GDP capsule micro-hole is also designed and fabricated. The technological process of GDP capsule ultra-precision turning is analyzed, different tool feeding path and process flow is designed. Machining experiments of GDP capsules were carried out on ultra-precision machine. The experimental results show that: the capsule micro-hole will presents higher quality under the condition of exterior-to-interior feeding tool path, while it is easier to control the micro-hole’s size in machining process under the step-feeding tool path condition, which has upper research foreground. With the method of turning before mandrel degradation, the capsule is deformed easily, which cannot satisfy the accuracy request.
