鑄鐵配重塊是用于增(zeng)加自身(shen)重(zhong)量來保持(chi)平衡的重(zhong)物，是將噴丸(wan)機(ji)熔煉成(cheng)符合 要求(qiu)的液(ye)體并澆進(jin)鑄型里(li)，經冷卻(que)凝固、清整處理后得到有預(yu)定形狀、尺寸和性能的鑄件的工藝過(guo)程。現代機(ji)械制造工業的基礎工藝之一(yi)。

　　廣泛應用于小家電、玩具等領域。這些領域鑄鐵配重塊的有的是為了保持自身重心的平衡穩定，裝載機配重塊有的(de)則是(shi)為了彌補產(chan)品本身重量(liang)(liang)過(guo)輕(qing)起(qi)到(dao)增加重量(liang)(liang)及手(shou)感的(de)作用。同時這(zhe)些領域應(ying)用鑄鐵配重塊有時也是(shi)一種合理的(de)設計選擇和經濟的(de)方法應(ying)用。

　　工(gong)作面(mian)小(xiao)范圍內的(de)(de)(de)局(ju)(ju)(ju)部變化是指加工(gong)表(biao)(biao)面(mian)不(bu)平(ping)整(zheng)，有變形(xing)，灰(hui)口鐵(tie)(tie)可以(yi)看(kan)作是鋼的(de)(de)(de)基體與片狀石墨(mo)的(de)(de)(de)夾雜(za)。因此(ci)石墨(mo)片越(yue)少(shao)，越(yue)細，為了(le)保證鑄(zhu)(zhu)(zhu)鐵(tie)(tie)在澆鑄(zhu)(zhu)(zhu)能夠得到灰(hui)口，且不(bu)至于(yu)得到過多和(he)粗大的(de)(de)(de)石墨(mo)片，這里所說的(de)(de)(de)工(gong)作面(mian)小(xiao)范圍，對(dui)小(xiao)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板而言是局(ju)(ju)(ju)部位(wei)置，對(dui)大鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板而言是局(ju)(ju)(ju)部面(mian)積。鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板的(de)(de)(de)平(ping)整(zheng)性反映了(le)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板局(ju)(ju)(ju)部誤差鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板的(de)(de)(de)局(ju)(ju)(ju)部誤差是指鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板工(gong)作面(mian)局(ju)(ju)(ju)部平(ping)面(mian)度加工(gong)質量，即表(biao)(biao)面(mian)粗糙度。
