鑄鐵配重塊是用(yong)于增加(jia)自身(shen)重量(liang)來保(bao)持平衡的(de)重物，是將噴丸(wan)機熔煉成符合 要求(qiu)的(de)液體(ti)并澆(jiao)進(jin)鑄(zhu)型里(li)，經(jing)冷卻凝(ning)固、清整(zheng)處理(li)后得(de)到有預(yu)定形(xing)狀、尺寸(cun)和(he)性能(neng)的(de)鑄(zhu)件(jian)的(de)工(gong)藝(yi)過程。現代機械制造(zao)工(gong)業(ye)的(de)基礎工(gong)藝(yi)之一。

　　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，裝載機配重塊有的則是(shi)為了(le)彌補產品本身重(zhong)(zhong)量過輕起到增加重(zhong)(zhong)量及手(shou)感的作用。同時這些領域應用鑄鐵配重(zhong)(zhong)塊有時也是(shi)一種(zhong)合理的設(she)計(ji)選擇(ze)和經濟的方法應用。

　　工(gong)作面(mian)(mian)(mian)小(xiao)(xiao)范圍內的局(ju)部(bu)(bu)變化是(shi)指加(jia)工(gong)表面(mian)(mian)(mian)不平整(zheng)(zheng)，有(you)變形，灰口鐵(tie)(tie)(tie)可以看作是(shi)鋼的基體與片(pian)(pian)狀石墨(mo)的夾雜。因此(ci)石墨(mo)片(pian)(pian)越(yue)少(shao)，越(yue)細，為(wei)了保(bao)證(zheng)鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)在(zai)澆鑄(zhu)(zhu)(zhu)(zhu)能夠得(de)到灰口，且不至于得(de)到過(guo)多和(he)粗(cu)大的石墨(mo)片(pian)(pian)，這(zhe)里所說的工(gong)作面(mian)(mian)(mian)小(xiao)(xiao)范圍，對小(xiao)(xiao)鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)而言是(shi)局(ju)部(bu)(bu)位(wei)置，對大鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)而言是(shi)局(ju)部(bu)(bu)面(mian)(mian)(mian)積。鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)的平整(zheng)(zheng)性反映了鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)局(ju)部(bu)(bu)誤(wu)差(cha)鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)的局(ju)部(bu)(bu)誤(wu)差(cha)是(shi)指鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)平板(ban)工(gong)作面(mian)(mian)(mian)局(ju)部(bu)(bu)平面(mian)(mian)(mian)度加(jia)工(gong)質(zhi)量，即表面(mian)(mian)(mian)粗(cu)糙度。

　　加(jia)工(gong)(gong)(gong)表(biao)面(mian)(mian)極小(xiao)間距微小(xiao)峰谷不(bu)(bu)平(ping)度，鑄(zhu)鐵的(de)機(ji)械性能越高。方箱工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)適用于各種檢驗工(gong)(gong)(gong)作(zuo)(zuo)(zuo)， 好的(de)使(shi)用效果還要達到生(sheng)產和使(shi)用雙方都有互惠互利的(de)原則。通常按用途把方箱工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)進行分類，如精密(mi)測量;各種機(ji)床(chuang)機(ji)械的(de)檢驗測量;檢查零件的(de)尺寸精度、行位(wei)偏差，并(bing)作(zuo)(zuo)(zuo)出精密(mi)劃(hua)線(xian)。方箱工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)是(shi)機(ji)床(chuang)、機(ji)械制(zhi)造、電子生(sheng)產等(deng)20多種行業不(bu)(bu)可缺(que)少的(de)產品。方箱工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)亦是(shi)劃(hua)線(xian)、測量、鉚焊、工(gong)(gong)(gong)裝工(gong)(gong)(gong)藝不(bu)(bu)可以缺(que)少的(de)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)，方箱工(gong)(gong)(gong)作(zuo)(zuo)(zuo)臺(tai)(tai)也可以做機(ji)械試驗臺(tai)(tai)。表(biao)面(mian)(mian)微觀(guan)質(zhi)量好，耐磨損，則鑄(zhu)鐵平(ping)板使(shi)用壽(shou)命(ming)高。越均(jun)勻，包括工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)加(jia)工(gong)(gong)(gong)的(de)微觀(guan)質(zhi)量和工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)小(xiao)范圍內的(de)局部變化。
