The molybdenum cup and molybdenum pin, which are the main materials of the molybdenum electrode used for the LCD BLU CCFL electrode, have not been developed in Japan and all of them are imported and used from Japan, is giving a competitive burden. In this research, the CCFL electrode of LCD BLU is used to develop the manufacturing technology of molybdenum pin. The development of linear processing technology is used to that. The development of molybdenum wire surface treatment technology is used to that. The development of wire cutting technology is ued to that. The design and fabrication of JIG and Fixture for inspection is used to that. The molybdenum pin prototyping and analysis is used to that and finally, the development of 100% molybdenum pin inspection technology is used to that. In this paper, especially, research on design technology of wire cutting is treated.

본 연구개발은 2m 이상 대형 석재에 대한 가공기계 개발에 관한 것으로서, 종전에 강철재 원형톱을 회전시켜 석재를 절단하던 방식을 개선하여 와이어에 공업용 다이아몬드를 장착한 와이어 쏘우를 절단도 구로 채용하였다. 또한 부수장치로 거대 석재를 전후좌우 및 회전이 가능하여 다각도 가공이 가능하도록 턴테이블식 공작물 베드를 설계 및 개발하였다. 한편 대형 석재 가공기계는 대부분 중국산 기계가 수입되어 사용되어지고 있으며, 이로 인한 장비 관리 및 사용에 있어서 여러 가지 불편한 점들이 산재해 있으나 국내 생산 제품이 전무하여 불편함을 감수하면서 어렵게 국내 석재산업을 유지하여 오고 있는 실정이다. 따라서 본 개발을 통해서 국내 석재산업의 활성화를 기대해 본다.
