鏜(tang)(tang)床(chuang)(chuang)(chuang)是一種能夠(gou)進行(xing)精(jing)密孔加工(gong)(gong)的機(ji)床(chuang)(chuang)(chuang)設備(bei)，其加工(gong)(gong)原理是利用刀具(ju)在(zai)被加工(gong)(gong)工(gong)(gong)件中(zhong)旋轉和(he)移動的方(fang)(fang)式(shi)來進行(xing)孔加工(gong)(gong)。鏜(tang)(tang)床(chuang)(chuang)(chuang)與其他孔加工(gong)(gong)方(fang)(fang)式(shi)相比，具(ju)有(you)高精(jing)度、高效率、高剛性等特點，因此在(zai)航空、汽車、機(ji)床(chuang)(chuang)(chuang)、電子(zi)、化工(gong)(gong)等領域中(zhong)被廣泛使用。鏜(tang)(tang)床(chuang)(chuang)(chuang)的分(fen)類1、按照結構類型，鏜(tang)(tang)床(chuang)(chuang)(chuang)可分(fen)為：立(li)式(shi)鏜(tang)(tang)床(chuang)(chuang)(chuang)、臥(wo)式(shi)鏜(tang)(tang)床(chuang)(chuang)(chuang)、落地式(shi)鏜(tang)(tang)床(chuang)(chuang)(chuang)、龍門式(shi)鏜(tang)(tang)床(chuang)(chuang)(chuang)、

航空工業(ye)，飛(fei)機(ji)機(ji)翼(yi)、機(ji)身、尾(wei)翼(yi)等(deng)(deng)和發動(dong)機(ji)零件的(de)制造需要大(da)批(pi)高(gao)速(su)五軸(zhou)(zhou)加(jia)工中(zhong)(zhong)心(xin)(xin)、龍門移動(dong)式高(gao)速(su)加(jia)工中(zhong)(zhong)心(xin)(xin)、精(jing)(jing)密(mi)數(shu)控(kong)車床(chuang)、精(jing)(jing)密(mi)臥(wo)(wo)式加(jia)工中(zhong)(zhong)心(xin)(xin)、多坐標鏜(tang)銑中(zhong)(zhong)心(xin)(xin)、精(jing)(jing)密(mi)齒輪(lun)和螺紋加(jia)工數(shu)控(kong)機(ji)床(chuang)等(deng)(deng)。航天工業(ye)需求大(da)批(pi)精(jing)(jing)密(mi)、高(gao)速(su)、中(zhong)(zhong)小(xiao)型數(shu)控(kong)機(ji)床(chuang)，如精(jing)(jing)密(mi)數(shu)控(kong)車床(chuang)和車削中(zhong)(zhong)心(xin)(xin)、立臥(wo)(wo)轉換(huan)五軸(zhou)(zhou)加(jia)工中(zhong)(zhong)心(xin)(xin)、高(gao)精(jing)(jing)度電加(jia)工機(ji)床(chuang)
