Abstract

터어빈 블레이드(Trubine blade)의 도브 테일(Dove tail)을 가공함에 있어 와이어 컷팅기로 1차 방전 가공한 다음 전해연마방식으로 연마가공함으로써 종래 기계가공방식에 의하여 가공된 제품보다 품질이 우수하고 가공 시간과 제조원가가 절감된다.In machining the dove tail of the turbine blade, it is first discharged with a wire cutting machine and then polished by electropolishing, which is superior in quality to products processed by conventional machining and Manufacturing cost is reduced.
