CNC加工方(fang)式也是(shi)會涉(she)及到壓鑄工(gong)(gong)藝在工(gong)(gong)業(ye)領域里，精密零(ling)件分為很多種(zhong)。由于每個行業(ye)所(suo)涉(she)及的(de)(de)(de)技(ji)術都是(shi)不同的(de)(de)(de)，因此(ci)所(suo)采用(yong)和(he)使用(yong)的(de)(de)(de)零(ling)件也是(shi)截然不同的(de)(de)(de)。由于零(ling)件的(de)(de)(de)造(zao)型不同，很多情況下(xia)它(ta)們(men)都要(yao)通過各(ge)種(zhong)加(jia)(jia)工(gong)(gong)方(fang)式來加(jia)(jia)強它(ta)的(de)(de)(de)質量和(he)相關(guan)的(de)(de)(de)屬(shu)性功(gong)能。現(xian)如今(jin)的(de)(de)(de)數控(kong)加(jia)(jia)工(gong)(gong)方(fang)式已經(jing)延(yan)伸(shen)到各(ge)種(zhong)制造(zao)領域，其中CNC加(jia)(jia)工(gong)(gong)方(fang)式也是(shi)一(yi)種(zhong)加(jia)(jia)強金(jin)屬(shu)產品的(de)(de)(de)常用(yong)手段。隨著(zhu)技(ji)術的(de)(de)(de)特點不斷地(di)提升，它(ta)的(de)(de)(de)加(jia)(jia)工(gong)(gong)質量也逐漸地(di)升級和(he)改造(zao)。

CNC加(jia)工(gong)(gong)(gong)中壓(ya)鑄(zhu)(zhu)工(gong)(gong)(gong)藝(yi)(yi)就是(shi)(shi)利用機(ji)器、模具(ju)和合(he)金等(deng)三大(da)要(yao)素，將(jiang)壓(ya)力(li)、速(su)(su)(su)度(du)及時(shi)(shi)間(jian)統一(yi)(yi)的(de)(de)(de)過(guo)程。用于金屬(shu)熱加(jia)工(gong)(gong)(gong)，壓(ya)力(li)的(de)(de)(de)存(cun)在是(shi)(shi)壓(ya)鑄(zhu)(zhu)工(gong)(gong)(gong)藝(yi)(yi)區別(bie)其(qi)他鑄(zhu)(zhu)造(zao)方法的(de)(de)(de)主要(yao)特點.。CNC加(jia)工(gong)(gong)(gong)的(de)(de)(de)壓(ya)力(li)鑄(zhu)(zhu)造(zao)是(shi)(shi)近代(dai)金屬(shu)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)中發展較快的(de)(de)(de)一(yi)(yi)種(zhong)少無切削的(de)(de)(de)特種(zhong)鑄(zhu)(zhu)造(zao)方法。它是(shi)(shi)將(jiang)熔融金屬(shu)在高(gao)壓(ya)高(gao)速(su)(su)(su)下充填鑄(zhu)(zhu)型，并在高(gao)壓(ya)下結晶凝固形成(cheng)鑄(zhu)(zhu)件的(de)(de)(de)過(guo)程。高(gao)壓(ya)高(gao)速(su)(su)(su)是(shi)(shi)壓(ya)力(li)鑄(zhu)(zhu)造(zao)的(de)(de)(de)主要(yao)特征(zheng)。常(chang)用的(de)(de)(de)壓(ya)力(li)為(wei)數十兆帕，填充速(su)(su)(su)度(du)（內澆口速(su)(su)(su)度(du)）約為(wei)16～80米/秒，金屬(shu)液填充模具(ju)型腔的(de)(de)(de)時(shi)(shi)間(jian)極短，約為(wei)0.01～0.2秒。

CNC加工(gong)(gong)中(zhong)壓(ya)(ya)鑄(zhu)(zhu)(zhu)工(gong)(gong)藝(yi)是將壓(ya)(ya)鑄(zhu)(zhu)(zhu)機(ji)、壓(ya)(ya)鑄(zhu)(zhu)(zhu)模和(he)合金(jin)三(san)大(da)要(yao)素有(you)機(ji)地組合而加以綜合運用(yong)的(de)(de)(de)過程(cheng)(cheng)。而壓(ya)(ya)鑄(zhu)(zhu)(zhu)時(shi)(shi)(shi)(shi)金(jin)屬按填充型腔的(de)(de)(de)過程(cheng)(cheng)，是將壓(ya)(ya)力、速度、溫度以及時(shi)(shi)(shi)(shi)間等(deng)工(gong)(gong)藝(yi)因(yin)素得到(dao)統一(yi)的(de)(de)(de)過程(cheng)(cheng)。同時(shi)(shi)(shi)(shi)，這些工(gong)(gong)藝(yi)因(yin)素又相互影響(xiang)，相互制(zhi)約，并(bing)且相輔相成。只有(you)正確選(xuan)擇和(he)調整(zheng)這些因(yin)素，使之協調一(yi)致，才能(neng)獲得預期(qi)的(de)(de)(de)結果(guo)。因(yin)此，在CNC加工(gong)(gong)壓(ya)(ya)鑄(zhu)(zhu)(zhu)過程(cheng)(cheng)中(zhong)不僅要(yao)重(zhong)視(shi)鑄(zhu)(zhu)(zhu)件結構的(de)(de)(de)工(gong)(gong)藝(yi)性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)(zhu)模的(de)(de)(de)先進(jin)(jin)性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)(zhu)機(ji)性(xing)(xing)能(neng)和(he)結構優良性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)(zhu)合金(jin)選(xuan)用(yong)的(de)(de)(de)適應性(xing)(xing)和(he)熔(rong)煉工(gong)(gong)藝(yi)的(de)(de)(de)規(gui)范性(xing)(xing)；更應重(zhong)視(shi)壓(ya)(ya)力、溫度和(he)時(shi)(shi)(shi)(shi)間等(deng)工(gong)(gong)藝(yi)參數(shu)對鑄(zhu)(zhu)(zhu)件質量的(de)(de)(de)重(zhong)要(yao)作(zuo)用(yong)。在壓(ya)(ya)鑄(zhu)(zhu)(zhu)過程(cheng)(cheng)中(zhong)應重(zhong)視(shi)對這些參數(shu)進(jin)(jin)行(xing)有(you)效的(de)(de)(de)控制(zhi)。
