CNC加工方(fang)式也(ye)是(shi)會涉及到壓鑄工(gong)藝在(zai)工(gong)業(ye)領域里，精密零件(jian)分為很(hen)多(duo)種(zhong)。由(you)于(yu)每(mei)個行業(ye)所(suo)涉及的(de)(de)(de)(de)技術都(dou)是(shi)不(bu)(bu)同的(de)(de)(de)(de)，因此所(suo)采用和使用的(de)(de)(de)(de)零件(jian)也(ye)是(shi)截然(ran)不(bu)(bu)同的(de)(de)(de)(de)。由(you)于(yu)零件(jian)的(de)(de)(de)(de)造(zao)(zao)型不(bu)(bu)同，很(hen)多(duo)情況(kuang)下它們都(dou)要通過各種(zhong)加(jia)(jia)工(gong)方(fang)式來(lai)加(jia)(jia)強它的(de)(de)(de)(de)質量(liang)和相關的(de)(de)(de)(de)屬性(xing)功能。現(xian)如今的(de)(de)(de)(de)數控加(jia)(jia)工(gong)方(fang)式已經延伸到各種(zhong)制造(zao)(zao)領域，其中CNC加(jia)(jia)工(gong)方(fang)式也(ye)是(shi)一種(zhong)加(jia)(jia)強金屬產(chan)品的(de)(de)(de)(de)常用手段。隨著技術的(de)(de)(de)(de)特點不(bu)(bu)斷地提升(sheng)，它的(de)(de)(de)(de)加(jia)(jia)工(gong)質量(liang)也(ye)逐漸(jian)地升(sheng)級和改造(zao)(zao)。

CNC加(jia)工(gong)(gong)中(zhong)(zhong)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)工(gong)(gong)藝(yi)就是利用機器、模具和(he)合金(jin)等(deng)三大要素，將(jiang)壓(ya)(ya)(ya)(ya)(ya)力(li)、速度(du)及時間統一(yi)的(de)(de)過(guo)程(cheng)。用于金(jin)屬熱加(jia)工(gong)(gong)，壓(ya)(ya)(ya)(ya)(ya)力(li)的(de)(de)存在是壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)工(gong)(gong)藝(yi)區別其他(ta)鑄(zhu)造(zao)方法的(de)(de)主要特點(dian).。CNC加(jia)工(gong)(gong)的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)鑄(zhu)造(zao)是近代金(jin)屬加(jia)工(gong)(gong)工(gong)(gong)藝(yi)中(zhong)(zhong)發展較快(kuai)的(de)(de)一(yi)種(zhong)少無切削的(de)(de)特種(zhong)鑄(zhu)造(zao)方法。它是將(jiang)熔融金(jin)屬在高(gao)壓(ya)(ya)(ya)(ya)(ya)高(gao)速下充填(tian)鑄(zhu)型，并在高(gao)壓(ya)(ya)(ya)(ya)(ya)下結晶凝(ning)固形成鑄(zhu)件的(de)(de)過(guo)程(cheng)。高(gao)壓(ya)(ya)(ya)(ya)(ya)高(gao)速是壓(ya)(ya)(ya)(ya)(ya)力(li)鑄(zhu)造(zao)的(de)(de)主要特征(zheng)。常用的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)為數十兆(zhao)帕(pa)，填(tian)充速度(du)（內(nei)澆(jiao)口速度(du)）約為16～80米/秒，金(jin)屬液(ye)填(tian)充模具型腔的(de)(de)時間極短，約為0.01～0.2秒。

CNC加工(gong)(gong)(gong)(gong)中壓(ya)(ya)鑄(zhu)工(gong)(gong)(gong)(gong)藝(yi)是將(jiang)壓(ya)(ya)鑄(zhu)機、壓(ya)(ya)鑄(zhu)模和(he)合金三大要素(su)有機地組合而加以(yi)綜合運(yun)用(yong)的(de)過程(cheng)(cheng)。而壓(ya)(ya)鑄(zhu)時(shi)金屬(shu)按填充型(xing)腔的(de)過程(cheng)(cheng)，是將(jiang)壓(ya)(ya)力、速度(du)、溫(wen)度(du)以(yi)及時(shi)間等工(gong)(gong)(gong)(gong)藝(yi)因(yin)素(su)得到統一(yi)的(de)過程(cheng)(cheng)。同時(shi)，這些工(gong)(gong)(gong)(gong)藝(yi)因(yin)素(su)又(you)相互影響，相互制(zhi)約(yue)，并(bing)且相輔相成。只有正確(que)選擇和(he)調(diao)(diao)整這些因(yin)素(su)，使之(zhi)協調(diao)(diao)一(yi)致，才能(neng)獲得預期的(de)結(jie)果。因(yin)此，在(zai)CNC加工(gong)(gong)(gong)(gong)壓(ya)(ya)鑄(zhu)過程(cheng)(cheng)中不僅要重(zhong)(zhong)視(shi)鑄(zhu)件結(jie)構(gou)的(de)工(gong)(gong)(gong)(gong)藝(yi)性(xing)，壓(ya)(ya)鑄(zhu)模的(de)先進(jin)性(xing)，壓(ya)(ya)鑄(zhu)機性(xing)能(neng)和(he)結(jie)構(gou)優良性(xing)，壓(ya)(ya)鑄(zhu)合金選用(yong)的(de)適應性(xing)和(he)熔煉工(gong)(gong)(gong)(gong)藝(yi)的(de)規范(fan)性(xing)；更應重(zhong)(zhong)視(shi)壓(ya)(ya)力、溫(wen)度(du)和(he)時(shi)間等工(gong)(gong)(gong)(gong)藝(yi)參數(shu)(shu)對鑄(zhu)件質(zhi)量的(de)重(zhong)(zhong)要作用(yong)。在(zai)壓(ya)(ya)鑄(zhu)過程(cheng)(cheng)中應重(zhong)(zhong)視(shi)對這些參數(shu)(shu)進(jin)行(xing)有效的(de)控制(zhi)。
