主(zhu)要(yao)用銑刀(dao)(dao)在(zai)工(gong)(gong)件(jian)上加工(gong)(gong)各(ge)(ge)種(zhong)表(biao)面(mian)(mian)的(de)機(ji)床(chuang)。通常銑刀(dao)(dao)旋轉(zhuan)運(yun)動為主(zhu)運(yun)動，工(gong)(gong)件(jian)（和(he)(he)）銑刀(dao)(dao)的(de)移(yi)動為進(jin)給運(yun)動。它可以(yi)加工(gong)(gong)平(ping)面(mian)(mian)、溝(gou)槽(cao)，也可以(yi)加工(gong)(gong)各(ge)(ge)種(zhong)曲面(mian)(mian)、齒(chi)輪等。銑床(chuang)是用銑刀(dao)(dao)對工(gong)(gong)件(jian)進(jin)行銑削加工(gong)(gong)的(de)機(ji)床(chuang)。銑床(chuang)除(chu)能(neng)(neng)銑削平(ping)面(mian)(mian)、溝(gou)槽(cao)、輪齒(chi)、螺紋(wen)和(he)(he)花鍵軸外，還能(neng)(neng)加工(gong)(gong)比較(jiao)復雜的(de)型面(mian)(mian)，效率(lv)較(jiao)刨床(chuang)高，在(zai)機(ji)械制造和(he)(he)修理部門得到(dao)廣泛應用。
