CNC加工方(fang)式也(ye)(ye)是(shi)會涉及到壓鑄工(gong)藝在工(gong)業(ye)領(ling)域(yu)(yu)里，精密零件分為很(hen)(hen)多種。由于每個行業(ye)所涉及的(de)(de)(de)技(ji)術都是(shi)不同(tong)(tong)的(de)(de)(de)，因此所采用(yong)和(he)使用(yong)的(de)(de)(de)零件也(ye)(ye)是(shi)截然不同(tong)(tong)的(de)(de)(de)。由于零件的(de)(de)(de)造(zao)(zao)型不同(tong)(tong)，很(hen)(hen)多情況(kuang)下它們都要通過(guo)各種加(jia)(jia)工(gong)方(fang)式來加(jia)(jia)強它的(de)(de)(de)質量和(he)相關(guan)的(de)(de)(de)屬(shu)(shu)性功能(neng)。現(xian)如今的(de)(de)(de)數控(kong)加(jia)(jia)工(gong)方(fang)式已經(jing)延伸(shen)到各種制(zhi)造(zao)(zao)領(ling)域(yu)(yu)，其中CNC加(jia)(jia)工(gong)方(fang)式也(ye)(ye)是(shi)一種加(jia)(jia)強金屬(shu)(shu)產品的(de)(de)(de)常(chang)用(yong)手(shou)段。隨著技(ji)術的(de)(de)(de)特(te)點不斷地(di)提升，它的(de)(de)(de)加(jia)(jia)工(gong)質量也(ye)(ye)逐漸(jian)地(di)升級(ji)和(he)改造(zao)(zao)。

CNC加(jia)工中(zhong)壓鑄(zhu)(zhu)(zhu)工藝就是(shi)(shi)利用(yong)機器、模(mo)具(ju)和(he)合金等(deng)三大(da)要(yao)(yao)素，將壓力(li)、速度及時間統一的過程(cheng)。用(yong)于金屬熱加(jia)工，壓力(li)的存在(zai)是(shi)(shi)壓鑄(zhu)(zhu)(zhu)工藝區別其他鑄(zhu)(zhu)(zhu)造方(fang)法(fa)的主(zhu)要(yao)(yao)特點.。CNC加(jia)工的壓力(li)鑄(zhu)(zhu)(zhu)造是(shi)(shi)近代金屬加(jia)工工藝中(zhong)發展較快(kuai)的一種少(shao)無切削的特種鑄(zhu)(zhu)(zhu)造方(fang)法(fa)。它(ta)是(shi)(shi)將熔融金屬在(zai)高壓高速下充(chong)(chong)填鑄(zhu)(zhu)(zhu)型，并(bing)在(zai)高壓下結晶凝固形成(cheng)鑄(zhu)(zhu)(zhu)件的過程(cheng)。高壓高速是(shi)(shi)壓力(li)鑄(zhu)(zhu)(zhu)造的主(zhu)要(yao)(yao)特征。常用(yong)的壓力(li)為數十兆帕，填充(chong)(chong)速度（內澆口速度）約為16～80米(mi)/秒，金屬液填充(chong)(chong)模(mo)具(ju)型腔的時間極短，約為0.01～0.2秒。

CNC加工(gong)(gong)(gong)中(zhong)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)工(gong)(gong)(gong)藝(yi)是將壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)機、壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)模(mo)和合(he)(he)金三大要素(su)有機地(di)組合(he)(he)而加以綜合(he)(he)運用的(de)過(guo)程(cheng)。而壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)時(shi)金屬按填(tian)充型腔(qiang)的(de)過(guo)程(cheng)，是將壓(ya)(ya)(ya)(ya)(ya)力、速度、溫度以及時(shi)間等工(gong)(gong)(gong)藝(yi)因(yin)素(su)得(de)到統一(yi)的(de)過(guo)程(cheng)。同時(shi)，這些工(gong)(gong)(gong)藝(yi)因(yin)素(su)又相互影響，相互制約，并且相輔(fu)相成。只有正確選擇和調整這些因(yin)素(su)，使(shi)之協調一(yi)致，才能獲得(de)預期的(de)結(jie)果。因(yin)此，在(zai)CNC加工(gong)(gong)(gong)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)過(guo)程(cheng)中(zhong)不僅(jin)要重視(shi)鑄(zhu)件(jian)結(jie)構的(de)工(gong)(gong)(gong)藝(yi)性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)模(mo)的(de)先進性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)機性(xing)能和結(jie)構優(you)良性(xing)，壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)合(he)(he)金選用的(de)適應(ying)性(xing)和熔煉工(gong)(gong)(gong)藝(yi)的(de)規范性(xing)；更應(ying)重視(shi)壓(ya)(ya)(ya)(ya)(ya)力、溫度和時(shi)間等工(gong)(gong)(gong)藝(yi)參(can)數對鑄(zhu)件(jian)質(zhi)量的(de)重要作用。在(zai)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)過(guo)程(cheng)中(zhong)應(ying)重視(shi)對這些參(can)數進行有效的(de)控制。
