　　1.機床鑄(zhu)件(jian)床身(shen)鑄(zhu)件(jian)耐(nai)磨性(xing)和消震性(xing)好。由(you)(you)于(yu)(yu)(yu)鑄(zhu)鐵中石(shi)(shi)墨(mo)有利于(yu)(yu)(yu)潤滑(hua)及貯油，所以耐(nai)磨性(xing)好。同樣，由(you)(you)于(yu)(yu)(yu)石(shi)(shi)墨(mo)的存(cun)在的消震性(xing)優于(yu)(yu)(yu)鋼。

　　2.機(ji)床(chuang)鑄件(jian)床(chuang)身鑄件(jian)工(gong)(gong)藝性能好(hao)。由(you)于(yu)(yu)灰口鑄鐵(tie)含碳(tan)量高(gao)，接近于(yu)(yu)共(gong)晶成(cheng)分，故熔點(dian)比(bi)較低，流(liu)動(dong)性良好(hao)，收縮率小，因此適宜于(yu)(yu)鑄造結構復雜(za)或薄壁(bi)鑄件(jian)。另外，由(you)于(yu)(yu)石墨使切削加工(gong)(gong)時易于(yu)(yu)形成(cheng)斷(duan)屑，所以灰口鑄鐵(tie)機(ji)床(chuang)鑄件(jian)床(chuang)身鑄件(jian)的(de)可切削加工(gong)(gong)性優于(yu)(yu)鋼。
