    大型龍(long)門銑加(jia)工(gong)是比(bi)較大型的機床，最小的大型龍(long)門銑加(jia)工(gong)都有1000mm以上的行程，并且被稱之為大型立式加(jia)工(gong)中心的終(zhong)結者(zhe)。

        大型龍門銑加工的結構分類：大型龍門銑加工的龍門架由兩個立柱、橫梁、滑鞍等部件組成，大型龍門銑加工依據龍門架可為定梁式、動梁式和動柱式大型龍門銑加工。頂梁式大型龍門銑加工的橫梁固定，工作臺移動;動梁式大型龍門銑加工的橫梁上下移動，工作臺誠前后移動;動柱式大型龍門銑加工工作臺固定，龍門架移動。大型龍門銑加工都是主軸與工作臺為筆直狀況的，比較合適加工大型類的零件。
 

        大(da)(da)型(xing)(xing)(xing)龍門(men)銑(xian)(xian)加工(gong)(gong)的(de)使用：大(da)(da)型(xing)(xing)(xing)龍門(men)銑(xian)(xian)加工(gong)(gong)歸于(yu)(yu)大(da)(da)機(ji)床，是專門(men)為(wei)了加工(gong)(gong)大(da)(da)零件(jian)而規(gui)劃的(de)大(da)(da)型(xing)(xing)(xing)機(ji)床，首要使用于(yu)(yu)重(zhong)工(gong)(gong)業職(zhi)業，比(bi)(bi)如飛(fei)(fei)機(ji)、轎車、船只等重(zhong)型(xing)(xing)(xing)職(zhi)業中(zhong)，首要加工(gong)(gong)大(da)(da)型(xing)(xing)(xing)雜亂形狀的(de)工(gong)(gong)件(jian)，比(bi)(bi)如加工(gong)(gong)飛(fei)(fei)機(ji)的(de)梁、框以(yi)及大(da)(da)型(xing)(xing)(xing)機(ji)械上的(de)某些(xie)零件(jian)等。總而言之(zhi)大(da)(da)型(xing)(xing)(xing)龍門(men)銑(xian)(xian)加工(gong)(gong)是為(wei)了加工(gong)(gong)大(da)(da)型(xing)(xing)(xing)雜亂零件(jian)而規(gui)劃的(de)一款大(da)(da)型(xing)(xing)(xing)機(ji)床，適(shi)用于(yu)(yu)各(ge)個職(zhi)業中(zhong)，特別是大(da)(da)型(xing)(xing)(xing)零件(jian)職(zhi)業。
