CNC加工方(fang)式也(ye)是會涉(she)及(ji)到(dao)壓鑄工(gong)藝在工(gong)業領域(yu)里，精密零件分為很(hen)多種(zhong)。由(you)于每(mei)個行業所涉(she)及(ji)的(de)(de)(de)技術都是不(bu)同的(de)(de)(de)，因(yin)此(ci)所采(cai)用和(he)使(shi)用的(de)(de)(de)零件也(ye)是截然(ran)不(bu)同的(de)(de)(de)。由(you)于零件的(de)(de)(de)造(zao)型不(bu)同，很(hen)多情況下它們都要通過(guo)各種(zhong)加(jia)(jia)工(gong)方(fang)式來加(jia)(jia)強它的(de)(de)(de)質(zhi)量和(he)相關的(de)(de)(de)屬性功能(neng)。現(xian)如(ru)今的(de)(de)(de)數控加(jia)(jia)工(gong)方(fang)式已經延伸到(dao)各種(zhong)制造(zao)領域(yu)，其中CNC加(jia)(jia)工(gong)方(fang)式也(ye)是一種(zhong)加(jia)(jia)強金屬產品(pin)的(de)(de)(de)常用手(shou)段(duan)。隨著技術的(de)(de)(de)特點不(bu)斷地(di)提(ti)升，它的(de)(de)(de)加(jia)(jia)工(gong)質(zhi)量也(ye)逐漸地(di)升級(ji)和(he)改(gai)造(zao)。

CNC加工(gong)(gong)中(zhong)壓(ya)(ya)鑄(zhu)(zhu)工(gong)(gong)藝就是利用機(ji)器、模具和合金(jin)(jin)等(deng)三大要素，將壓(ya)(ya)力、速(su)度及(ji)時間統(tong)一的(de)過程(cheng)。用于金(jin)(jin)屬熱(re)加工(gong)(gong)，壓(ya)(ya)力的(de)存在(zai)是壓(ya)(ya)鑄(zhu)(zhu)工(gong)(gong)藝區別其他鑄(zhu)(zhu)造(zao)方法(fa)(fa)的(de)主(zhu)要特點(dian).。CNC加工(gong)(gong)的(de)壓(ya)(ya)力鑄(zhu)(zhu)造(zao)是近代金(jin)(jin)屬加工(gong)(gong)工(gong)(gong)藝中(zhong)發展較快的(de)一種(zhong)少(shao)無切(qie)削的(de)特種(zhong)鑄(zhu)(zhu)造(zao)方法(fa)(fa)。它是將熔融金(jin)(jin)屬在(zai)高(gao)(gao)壓(ya)(ya)高(gao)(gao)速(su)下充填(tian)(tian)鑄(zhu)(zhu)型，并在(zai)高(gao)(gao)壓(ya)(ya)下結晶凝固形成鑄(zhu)(zhu)件的(de)過程(cheng)。高(gao)(gao)壓(ya)(ya)高(gao)(gao)速(su)是壓(ya)(ya)力鑄(zhu)(zhu)造(zao)的(de)主(zhu)要特征。常用的(de)壓(ya)(ya)力為數十(shi)兆帕，填(tian)(tian)充速(su)度（內澆(jiao)口速(su)度）約為16～80米/秒，金(jin)(jin)屬液填(tian)(tian)充模具型腔的(de)時間極短，約為0.01～0.2秒。

CNC加(jia)工(gong)(gong)中壓(ya)(ya)鑄(zhu)工(gong)(gong)藝是將壓(ya)(ya)鑄(zhu)機(ji)、壓(ya)(ya)鑄(zhu)模(mo)和(he)合(he)(he)金三大要(yao)素有(you)機(ji)地組合(he)(he)而加(jia)以(yi)綜(zong)合(he)(he)運用(yong)的(de)過(guo)程。而壓(ya)(ya)鑄(zhu)時(shi)金屬按填充型腔的(de)過(guo)程，是將壓(ya)(ya)力、速度、溫度以(yi)及時(shi)間等工(gong)(gong)藝因(yin)素得到(dao)統(tong)一的(de)過(guo)程。同(tong)時(shi)，這些(xie)工(gong)(gong)藝因(yin)素又相互影響，相互制(zhi)約(yue)，并(bing)且相輔相成。只有(you)正確選擇和(he)調(diao)整這些(xie)因(yin)素，使之協調(diao)一致，才能(neng)獲(huo)得預期的(de)結果。因(yin)此，在CNC加(jia)工(gong)(gong)壓(ya)(ya)鑄(zhu)過(guo)程中不僅要(yao)重(zhong)視(shi)鑄(zhu)件結構的(de)工(gong)(gong)藝性(xing)(xing)，壓(ya)(ya)鑄(zhu)模(mo)的(de)先進(jin)性(xing)(xing)，壓(ya)(ya)鑄(zhu)機(ji)性(xing)(xing)能(neng)和(he)結構優良(liang)性(xing)(xing)，壓(ya)(ya)鑄(zhu)合(he)(he)金選用(yong)的(de)適應性(xing)(xing)和(he)熔(rong)煉工(gong)(gong)藝的(de)規范性(xing)(xing)；更應重(zhong)視(shi)壓(ya)(ya)力、溫度和(he)時(shi)間等工(gong)(gong)藝參數對(dui)鑄(zhu)件質(zhi)量的(de)重(zhong)要(yao)作用(yong)。在壓(ya)(ya)鑄(zhu)過(guo)程中應重(zhong)視(shi)對(dui)這些(xie)參數進(jin)行有(you)效的(de)控(kong)制(zhi)。
