CNC加工方(fang)式(shi)也是會涉(she)及(ji)到壓鑄工(gong)藝在(zai)工(gong)業領域里，精密零(ling)(ling)件(jian)分為很多種(zhong)(zhong)。由于每個行業所涉(she)及(ji)的(de)技(ji)術(shu)都(dou)是不同(tong)的(de)，因(yin)此(ci)所采用(yong)和使用(yong)的(de)零(ling)(ling)件(jian)也是截然不同(tong)的(de)。由于零(ling)(ling)件(jian)的(de)造(zao)型不同(tong)，很多情況(kuang)下(xia)它們都(dou)要(yao)通過各種(zhong)(zhong)加(jia)工(gong)方(fang)式(shi)來加(jia)強它的(de)質(zhi)(zhi)量和相關(guan)的(de)屬性(xing)功能。現如今的(de)數控加(jia)工(gong)方(fang)式(shi)已經延(yan)伸到各種(zhong)(zhong)制(zhi)造(zao)領域，其中CNC加(jia)工(gong)方(fang)式(shi)也是一種(zhong)(zhong)加(jia)強金屬產品的(de)常用(yong)手(shou)段(duan)。隨著(zhu)技(ji)術(shu)的(de)特點不斷地(di)提升，它的(de)加(jia)工(gong)質(zhi)(zhi)量也逐漸地(di)升級和改造(zao)。

CNC加(jia)工(gong)(gong)(gong)(gong)中壓(ya)鑄(zhu)工(gong)(gong)(gong)(gong)藝就是(shi)(shi)利(li)用機器、模(mo)具和合金(jin)(jin)等(deng)三大要素，將(jiang)壓(ya)力(li)(li)、速(su)度(du)及時間統一(yi)的(de)(de)(de)過(guo)程。用于金(jin)(jin)屬(shu)(shu)熱加(jia)工(gong)(gong)(gong)(gong)，壓(ya)力(li)(li)的(de)(de)(de)存在是(shi)(shi)壓(ya)鑄(zhu)工(gong)(gong)(gong)(gong)藝區別(bie)其他鑄(zhu)造(zao)(zao)方法的(de)(de)(de)主(zhu)要特(te)點.。CNC加(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)壓(ya)力(li)(li)鑄(zhu)造(zao)(zao)是(shi)(shi)近代金(jin)(jin)屬(shu)(shu)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝中發展較快的(de)(de)(de)一(yi)種少無(wu)切削的(de)(de)(de)特(te)種鑄(zhu)造(zao)(zao)方法。它是(shi)(shi)將(jiang)熔融金(jin)(jin)屬(shu)(shu)在高(gao)(gao)壓(ya)高(gao)(gao)速(su)下充(chong)填(tian)鑄(zhu)型，并在高(gao)(gao)壓(ya)下結晶凝固(gu)形成鑄(zhu)件的(de)(de)(de)過(guo)程。高(gao)(gao)壓(ya)高(gao)(gao)速(su)是(shi)(shi)壓(ya)力(li)(li)鑄(zhu)造(zao)(zao)的(de)(de)(de)主(zhu)要特(te)征。常用的(de)(de)(de)壓(ya)力(li)(li)為(wei)數十兆帕，填(tian)充(chong)速(su)度(du)（內澆(jiao)口速(su)度(du)）約為(wei)16～80米/秒，金(jin)(jin)屬(shu)(shu)液填(tian)充(chong)模(mo)具型腔(qiang)的(de)(de)(de)時間極短，約為(wei)0.01～0.2秒。

CNC加工(gong)中壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)工(gong)藝(yi)是將壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)機、壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)模(mo)和(he)合金三大要素有(you)(you)機地組合而加以綜合運用(yong)的(de)(de)(de)過(guo)程(cheng)。而壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)時(shi)金屬按填充型腔(qiang)的(de)(de)(de)過(guo)程(cheng)，是將壓(ya)(ya)(ya)(ya)(ya)力、速度、溫(wen)度以及時(shi)間等(deng)工(gong)藝(yi)因素得到統(tong)一的(de)(de)(de)過(guo)程(cheng)。同時(shi)，這些工(gong)藝(yi)因素又(you)相互(hu)(hu)影響，相互(hu)(hu)制約，并(bing)且(qie)相輔相成。只有(you)(you)正確選擇和(he)調整這些因素，使之(zhi)協(xie)調一致，才能(neng)獲得預期的(de)(de)(de)結果(guo)。因此(ci)，在CNC加工(gong)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)過(guo)程(cheng)中不僅要重(zhong)視(shi)鑄(zhu)(zhu)(zhu)(zhu)件結構(gou)的(de)(de)(de)工(gong)藝(yi)性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)模(mo)的(de)(de)(de)先進(jin)性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)機性(xing)能(neng)和(he)結構(gou)優良性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)合金選用(yong)的(de)(de)(de)適應性(xing)和(he)熔(rong)煉工(gong)藝(yi)的(de)(de)(de)規范性(xing)；更應重(zhong)視(shi)壓(ya)(ya)(ya)(ya)(ya)力、溫(wen)度和(he)時(shi)間等(deng)工(gong)藝(yi)參數(shu)對鑄(zhu)(zhu)(zhu)(zhu)件質量的(de)(de)(de)重(zhong)要作(zuo)用(yong)。在壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)過(guo)程(cheng)中應重(zhong)視(shi)對這些參數(shu)進(jin)行(xing)有(you)(you)效的(de)(de)(de)控制。
