CNC加工方(fang)(fang)式也(ye)(ye)是會(hui)涉(she)及到壓鑄工(gong)(gong)藝在(zai)工(gong)(gong)業(ye)領(ling)域里(li)，精密零(ling)(ling)件分(fen)為(wei)很(hen)多種(zhong)(zhong)。由于每個行業(ye)所涉(she)及的(de)(de)(de)技(ji)術都是不(bu)同的(de)(de)(de)，因此(ci)所采用和(he)使用的(de)(de)(de)零(ling)(ling)件也(ye)(ye)是截然(ran)不(bu)同的(de)(de)(de)。由于零(ling)(ling)件的(de)(de)(de)造型不(bu)同，很(hen)多情況下它(ta)們都要通(tong)過各(ge)種(zhong)(zhong)加(jia)(jia)(jia)工(gong)(gong)方(fang)(fang)式來(lai)加(jia)(jia)(jia)強(qiang)(qiang)它(ta)的(de)(de)(de)質量(liang)和(he)相關的(de)(de)(de)屬性功能。現如今的(de)(de)(de)數控(kong)加(jia)(jia)(jia)工(gong)(gong)方(fang)(fang)式已經延伸到各(ge)種(zhong)(zhong)制造領(ling)域，其中(zhong)CNC加(jia)(jia)(jia)工(gong)(gong)方(fang)(fang)式也(ye)(ye)是一種(zhong)(zhong)加(jia)(jia)(jia)強(qiang)(qiang)金(jin)屬產品的(de)(de)(de)常用手段。隨著技(ji)術的(de)(de)(de)特點不(bu)斷地提升，它(ta)的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)質量(liang)也(ye)(ye)逐漸地升級和(he)改造。

CNC加(jia)工中壓(ya)(ya)(ya)(ya)(ya)(ya)鑄工藝(yi)就是(shi)(shi)利用機器(qi)、模(mo)具和合金(jin)等三大(da)要素，將壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)、速度及(ji)時間(jian)統一的過(guo)程。用于金(jin)屬熱(re)加(jia)工，壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)的存在是(shi)(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)鑄工藝(yi)區別其他鑄造(zao)方法(fa)的主(zhu)要特(te)點(dian).。CNC加(jia)工的壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)鑄造(zao)是(shi)(shi)近代金(jin)屬加(jia)工工藝(yi)中發展較快的一種(zhong)少無(wu)切削的特(te)種(zhong)鑄造(zao)方法(fa)。它是(shi)(shi)將熔融(rong)金(jin)屬在高壓(ya)(ya)(ya)(ya)(ya)(ya)高速下充填鑄型(xing)，并(bing)在高壓(ya)(ya)(ya)(ya)(ya)(ya)下結(jie)晶凝固形成鑄件的過(guo)程。高壓(ya)(ya)(ya)(ya)(ya)(ya)高速是(shi)(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)鑄造(zao)的主(zhu)要特(te)征。常用的壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)為數(shu)十兆帕，填充速度（內澆口速度）約(yue)為16～80米/秒(miao)，金(jin)屬液填充模(mo)具型(xing)腔的時間(jian)極短，約(yue)為0.01～0.2秒(miao)。

CNC加工(gong)中(zhong)(zhong)壓(ya)(ya)鑄(zhu)(zhu)工(gong)藝(yi)是(shi)將壓(ya)(ya)鑄(zhu)(zhu)機、壓(ya)(ya)鑄(zhu)(zhu)模(mo)和(he)合(he)金(jin)三大要(yao)素有(you)機地組合(he)而加以綜(zong)合(he)運用的(de)過(guo)程。而壓(ya)(ya)鑄(zhu)(zhu)時(shi)金(jin)屬按填充型腔的(de)過(guo)程，是(shi)將壓(ya)(ya)力、速(su)度、溫度以及時(shi)間等工(gong)藝(yi)因(yin)素得(de)(de)到統(tong)一(yi)的(de)過(guo)程。同時(shi)，這些工(gong)藝(yi)因(yin)素又相(xiang)互影響，相(xiang)互制約，并且相(xiang)輔(fu)相(xiang)成。只有(you)正(zheng)確選擇和(he)調(diao)整這些因(yin)素，使(shi)之協調(diao)一(yi)致，才能(neng)獲(huo)得(de)(de)預(yu)期的(de)結果。因(yin)此，在CNC加工(gong)壓(ya)(ya)鑄(zhu)(zhu)過(guo)程中(zhong)(zhong)不僅要(yao)重(zhong)(zhong)視(shi)鑄(zhu)(zhu)件結構的(de)工(gong)藝(yi)性(xing)，壓(ya)(ya)鑄(zhu)(zhu)模(mo)的(de)先進(jin)性(xing)，壓(ya)(ya)鑄(zhu)(zhu)機性(xing)能(neng)和(he)結構優良性(xing)，壓(ya)(ya)鑄(zhu)(zhu)合(he)金(jin)選用的(de)適應性(xing)和(he)熔煉工(gong)藝(yi)的(de)規范性(xing)；更(geng)應重(zhong)(zhong)視(shi)壓(ya)(ya)力、溫度和(he)時(shi)間等工(gong)藝(yi)參數對鑄(zhu)(zhu)件質量的(de)重(zhong)(zhong)要(yao)作(zuo)用。在壓(ya)(ya)鑄(zhu)(zhu)過(guo)程中(zhong)(zhong)應重(zhong)(zhong)視(shi)對這些參數進(jin)行有(you)效的(de)控制。
