Recently, wind turbine system capacity has been increased more and more to coped with adaptive electric supply as the national green energy policy is carried out strongly. Wind turbine blade is also increased in size to satisfy sufficiently characteristic desired. Such extra large sized wind turbine blade manufactured with GFRP material needs trimming process certainly due to production method. High efficient type automatic trimming system model with sufficient energy saving effect is established in this study to prevent serious environment problems occurred in manual work process.

It is not efficient and scarcely out of the question to use commercial expensive electron beam lithography system widely used for semiconductor fabrication process for the manufacturing application field of various devices in the small business scope. Then scanning electron microscope based electron beam machining system is maybe regarded as a powerful model can be used for it simply. To get a complete suite of thus proper system, column unit build up with several electo-magnetic lens is necessarily required more than anything else to modify scanning electron microscope. In this study, various components included several electro-magnetic lens and main body which are essentially constructed for column unit are designed and manufactured. And this established column unit will be used for next connected study in the development step of scanning electron microscope based electron beam machining system.
