銑(xian)(xian)(xian)床(chuang)是種(zhong)用途廣泛(fan)的機床(chuang)，在(zai)銑(xian)(xian)(xian)床(chuang)上可(ke)以加(jia)(jia)工(gong)(gong)平面(mian)(mian)(mian)（水平面(mian)(mian)(mian)、垂直面(mian)(mian)(mian)）、溝槽(cao)(cao)(cao)(cao)（鍵槽(cao)(cao)(cao)(cao)、T形槽(cao)(cao)(cao)(cao)、燕尾槽(cao)(cao)(cao)(cao)等）、分齒(chi)零件（齒(chi)輪、花鍵軸、鏈輪）、螺(luo)旋(xuan)形表面(mian)(mian)(mian)（螺(luo)紋(wen)、螺(luo)旋(xuan)槽(cao)(cao)(cao)(cao)）及各種(zhong)曲面(mian)(mian)(mian)。此外，還可(ke)用于(yu)(yu)對(dui)回轉(zhuan)體(ti)表面(mian)(mian)(mian)、內孔加(jia)(jia)工(gong)(gong)及進(jin)行切斷工(gong)(gong)作等。銑(xian)(xian)(xian)床(chuang)在(zai)工(gong)(gong)作時，工(gong)(gong)件裝在(zai)工(gong)(gong)作臺(tai)上或分度(du)頭(tou)等附(fu)件上，銑(xian)(xian)(xian)刀旋(xuan)轉(zhuan)為(wei)主(zhu)運動，輔以工(gong)(gong)作臺(tai)或銑(xian)(xian)(xian)頭(tou)的進(jin)給運動，工(gong)(gong)件即可(ke)獲得(de)所需的加(jia)(jia)工(gong)(gong)表面(mian)(mian)(mian)。由于(yu)(yu)是多(duo)刃斷續切削(xue)(xue)，因而銑(xian)(xian)(xian)床(chuang)的生產率(lv)較(jiao)高。簡(jian)單(dan)來說(shuo)，銑(xian)(xian)(xian)床(chuang)可(ke)以對(dui)工(gong)(gong)件進(jin)行銑(xian)(xian)(xian)削(xue)(xue)、鉆削(xue)(xue)和鏜孔加(jia)(jia)工(gong)(gong)的機床(chuang)。
