CNC加工方式也是(shi)會(hui)涉(she)及到壓鑄工(gong)(gong)藝在工(gong)(gong)業領域里(li)，精密零(ling)件(jian)分為很多(duo)種(zhong)(zhong)。由(you)于每個(ge)行業所涉(she)及的(de)(de)技術都是(shi)不(bu)同(tong)的(de)(de)，因此所采用(yong)和(he)使用(yong)的(de)(de)零(ling)件(jian)也是(shi)截然(ran)不(bu)同(tong)的(de)(de)。由(you)于零(ling)件(jian)的(de)(de)造型(xing)不(bu)同(tong)，很多(duo)情況下它們都要(yao)通過各種(zhong)(zhong)加(jia)(jia)(jia)工(gong)(gong)方式來加(jia)(jia)(jia)強它的(de)(de)質量(liang)和(he)相關的(de)(de)屬性功(gong)能。現如今的(de)(de)數控(kong)加(jia)(jia)(jia)工(gong)(gong)方式已(yi)經延(yan)伸到各種(zhong)(zhong)制造領域，其(qi)中(zhong)CNC加(jia)(jia)(jia)工(gong)(gong)方式也是(shi)一種(zhong)(zhong)加(jia)(jia)(jia)強金屬產品(pin)的(de)(de)常用(yong)手段。隨著技術的(de)(de)特點不(bu)斷地提升(sheng)，它的(de)(de)加(jia)(jia)(jia)工(gong)(gong)質量(liang)也逐漸地升(sheng)級和(he)改造。

CNC加工(gong)中壓(ya)(ya)鑄(zhu)工(gong)藝就(jiu)是利(li)用(yong)機(ji)器、模具和合金(jin)(jin)等(deng)三大(da)要(yao)素，將壓(ya)(ya)力(li)、速度及時間(jian)統一(yi)的(de)過程(cheng)。用(yong)于金(jin)(jin)屬熱(re)加工(gong)，壓(ya)(ya)力(li)的(de)存在(zai)(zai)是壓(ya)(ya)鑄(zhu)工(gong)藝區別(bie)其他鑄(zhu)造方(fang)法(fa)的(de)主(zhu)要(yao)特點.。CNC加工(gong)的(de)壓(ya)(ya)力(li)鑄(zhu)造是近代金(jin)(jin)屬加工(gong)工(gong)藝中發展較快(kuai)的(de)一(yi)種(zhong)少無切(qie)削(xue)的(de)特種(zhong)鑄(zhu)造方(fang)法(fa)。它(ta)是將熔(rong)融金(jin)(jin)屬在(zai)(zai)高(gao)(gao)壓(ya)(ya)高(gao)(gao)速下充(chong)填鑄(zhu)型，并(bing)在(zai)(zai)高(gao)(gao)壓(ya)(ya)下結晶凝固形成鑄(zhu)件的(de)過程(cheng)。高(gao)(gao)壓(ya)(ya)高(gao)(gao)速是壓(ya)(ya)力(li)鑄(zhu)造的(de)主(zhu)要(yao)特征。常(chang)用(yong)的(de)壓(ya)(ya)力(li)為數十兆帕，填充(chong)速度（內澆口(kou)速度）約(yue)為16～80米/秒，金(jin)(jin)屬液填充(chong)模具型腔的(de)時間(jian)極(ji)短，約(yue)為0.01～0.2秒。

CNC加(jia)工(gong)(gong)中(zhong)壓(ya)(ya)(ya)鑄(zhu)(zhu)工(gong)(gong)藝(yi)是將壓(ya)(ya)(ya)鑄(zhu)(zhu)機(ji)、壓(ya)(ya)(ya)鑄(zhu)(zhu)模和(he)合金(jin)三大要(yao)素(su)有機(ji)地(di)組合而加(jia)以綜合運用(yong)的(de)(de)(de)過(guo)(guo)程。而壓(ya)(ya)(ya)鑄(zhu)(zhu)時(shi)金(jin)屬按填(tian)充型腔的(de)(de)(de)過(guo)(guo)程，是將壓(ya)(ya)(ya)力、速度、溫度以及時(shi)間(jian)等(deng)工(gong)(gong)藝(yi)因(yin)素(su)得(de)(de)到統一的(de)(de)(de)過(guo)(guo)程。同時(shi)，這(zhe)些工(gong)(gong)藝(yi)因(yin)素(su)又相(xiang)互影響，相(xiang)互制約，并且(qie)相(xiang)輔相(xiang)成。只有正確選擇和(he)調整(zheng)這(zhe)些因(yin)素(su)，使之(zhi)協(xie)調一致，才能獲得(de)(de)預期的(de)(de)(de)結果(guo)。因(yin)此，在(zai)CNC加(jia)工(gong)(gong)壓(ya)(ya)(ya)鑄(zhu)(zhu)過(guo)(guo)程中(zhong)不(bu)僅要(yao)重視鑄(zhu)(zhu)件(jian)結構的(de)(de)(de)工(gong)(gong)藝(yi)性(xing)(xing)，壓(ya)(ya)(ya)鑄(zhu)(zhu)模的(de)(de)(de)先進性(xing)(xing)，壓(ya)(ya)(ya)鑄(zhu)(zhu)機(ji)性(xing)(xing)能和(he)結構優良性(xing)(xing)，壓(ya)(ya)(ya)鑄(zhu)(zhu)合金(jin)選用(yong)的(de)(de)(de)適應(ying)(ying)性(xing)(xing)和(he)熔煉工(gong)(gong)藝(yi)的(de)(de)(de)規范性(xing)(xing)；更應(ying)(ying)重視壓(ya)(ya)(ya)力、溫度和(he)時(shi)間(jian)等(deng)工(gong)(gong)藝(yi)參數(shu)(shu)對(dui)鑄(zhu)(zhu)件(jian)質量(liang)的(de)(de)(de)重要(yao)作用(yong)。在(zai)壓(ya)(ya)(ya)鑄(zhu)(zhu)過(guo)(guo)程中(zhong)應(ying)(ying)重視對(dui)這(zhe)些參數(shu)(shu)進行(xing)有效的(de)(de)(de)控制。
