銑(xian)床(chuang)(chuang)（millingmachine）系指主要用銑(xian)刀(dao)(dao)在(zai)工(gong)(gong)件上加工(gong)(gong)各種表(biao)面的(de)機(ji)床(chuang)(chuang)。通常銑(xian)刀(dao)(dao)旋轉運動(dong)為(wei)主運動(dong)，工(gong)(gong)件（和）銑(xian)刀(dao)(dao)的(de)移動(dong)為(wei)進給運動(dong)。它可(ke)以加工(gong)(gong)平面、溝槽，也可(ke)以加工(gong)(gong)各種曲(qu)面、齒輪等。銑(xian)床(chuang)(chuang)是用銑(xian)刀(dao)(dao)對(dui)工(gong)(gong)件進行(xing)銑(xian)削加工(gong)(gong)的(de)機(ji)床(chuang)(chuang)。銑(xian)床(chuang)(chuang)除能(neng)銑(xian)削平面、溝槽、輪齒、螺(luo)紋和花鍵軸外(wai)，還能(neng)加工(gong)(gong)比(bi)較(jiao)復雜的(de)型(xing)面，效率較(jiao)刨床(chuang)(chuang)高(gao)，在(zai)機(ji)械制造和修理部門得到廣(guang)泛應(ying)用。
