CNC加工方(fang)式也(ye)(ye)是(shi)(shi)會(hui)涉及(ji)到壓鑄工(gong)(gong)(gong)藝在(zai)工(gong)(gong)(gong)業領域(yu)里(li)，精(jing)密零件(jian)(jian)分為很(hen)多種(zhong)。由(you)于每(mei)個行(xing)業所涉及(ji)的技術(shu)(shu)都(dou)是(shi)(shi)不同(tong)的，因此(ci)所采用(yong)和使用(yong)的零件(jian)(jian)也(ye)(ye)是(shi)(shi)截然不同(tong)的。由(you)于零件(jian)(jian)的造(zao)型不同(tong)，很(hen)多情況下它(ta)們都(dou)要通(tong)過各(ge)種(zhong)加(jia)(jia)工(gong)(gong)(gong)方(fang)式來加(jia)(jia)強它(ta)的質(zhi)量和相關的屬性功能。現如今(jin)的數控(kong)加(jia)(jia)工(gong)(gong)(gong)方(fang)式已(yi)經(jing)延伸到各(ge)種(zhong)制(zhi)造(zao)領域(yu)，其中CNC加(jia)(jia)工(gong)(gong)(gong)方(fang)式也(ye)(ye)是(shi)(shi)一種(zhong)加(jia)(jia)強金屬產品的常用(yong)手段。隨著技術(shu)(shu)的特點(dian)不斷地提升，它(ta)的加(jia)(jia)工(gong)(gong)(gong)質(zhi)量也(ye)(ye)逐(zhu)漸地升級和改造(zao)。

CNC加工中(zhong)壓(ya)(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)工藝就(jiu)是利用機器、模(mo)具和合(he)金等(deng)三大要素，將壓(ya)(ya)(ya)(ya)(ya)(ya)力、速度(du)及時(shi)間統一的(de)(de)(de)過程。用于金屬(shu)熱加工，壓(ya)(ya)(ya)(ya)(ya)(ya)力的(de)(de)(de)存在(zai)是壓(ya)(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)工藝區別其他鑄(zhu)(zhu)造(zao)方法的(de)(de)(de)主要特(te)點.。CNC加工的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力鑄(zhu)(zhu)造(zao)是近代金屬(shu)加工工藝中(zhong)發展較快(kuai)的(de)(de)(de)一種少(shao)無切削的(de)(de)(de)特(te)種鑄(zhu)(zhu)造(zao)方法。它是將熔融金屬(shu)在(zai)高壓(ya)(ya)(ya)(ya)(ya)(ya)高速下(xia)充(chong)(chong)填(tian)(tian)鑄(zhu)(zhu)型，并在(zai)高壓(ya)(ya)(ya)(ya)(ya)(ya)下(xia)結晶凝固形成(cheng)鑄(zhu)(zhu)件的(de)(de)(de)過程。高壓(ya)(ya)(ya)(ya)(ya)(ya)高速是壓(ya)(ya)(ya)(ya)(ya)(ya)力鑄(zhu)(zhu)造(zao)的(de)(de)(de)主要特(te)征(zheng)。常用的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力為數十兆帕，填(tian)(tian)充(chong)(chong)速度(du)（內(nei)澆口(kou)速度(du)）約為16～80米/秒，金屬(shu)液填(tian)(tian)充(chong)(chong)模(mo)具型腔(qiang)的(de)(de)(de)時(shi)間極短，約為0.01～0.2秒。

CNC加(jia)工(gong)(gong)(gong)中壓(ya)(ya)鑄(zhu)工(gong)(gong)(gong)藝是(shi)將壓(ya)(ya)鑄(zhu)機、壓(ya)(ya)鑄(zhu)模和(he)合金三(san)大要(yao)素(su)(su)有機地(di)組合而加(jia)以綜合運用(yong)的(de)過(guo)(guo)程(cheng)。而壓(ya)(ya)鑄(zhu)時金屬按填充型腔的(de)過(guo)(guo)程(cheng)，是(shi)將壓(ya)(ya)力(li)、速度、溫度以及時間等(deng)工(gong)(gong)(gong)藝因素(su)(su)得(de)到統(tong)一的(de)過(guo)(guo)程(cheng)。同(tong)時，這(zhe)些工(gong)(gong)(gong)藝因素(su)(su)又(you)相(xiang)互影響，相(xiang)互制(zhi)約，并且相(xiang)輔相(xiang)成(cheng)。只有正確(que)選(xuan)擇和(he)調整這(zhe)些因素(su)(su)，使(shi)之協調一致，才能獲得(de)預期的(de)結(jie)果。因此，在CNC加(jia)工(gong)(gong)(gong)壓(ya)(ya)鑄(zhu)過(guo)(guo)程(cheng)中不僅要(yao)重視(shi)鑄(zhu)件(jian)結(jie)構(gou)的(de)工(gong)(gong)(gong)藝性(xing)(xing)，壓(ya)(ya)鑄(zhu)模的(de)先進性(xing)(xing)，壓(ya)(ya)鑄(zhu)機性(xing)(xing)能和(he)結(jie)構(gou)優(you)良(liang)性(xing)(xing)，壓(ya)(ya)鑄(zhu)合金選(xuan)用(yong)的(de)適應性(xing)(xing)和(he)熔煉工(gong)(gong)(gong)藝的(de)規范性(xing)(xing)；更應重視(shi)壓(ya)(ya)力(li)、溫度和(he)時間等(deng)工(gong)(gong)(gong)藝參數對鑄(zhu)件(jian)質量(liang)的(de)重要(yao)作用(yong)。在壓(ya)(ya)鑄(zhu)過(guo)(guo)程(cheng)中應重視(shi)對這(zhe)些參數進行有效的(de)控制(zhi)。
