CNC加工方式也(ye)是(shi)會涉(she)及到(dao)壓鑄工(gong)藝在工(gong)業(ye)領域(yu)里，精密(mi)零(ling)件(jian)分為很多種。由于每個行業(ye)所(suo)涉(she)及的技術都(dou)是(shi)不同(tong)(tong)的，因此所(suo)采(cai)用(yong)和使用(yong)的零(ling)件(jian)也(ye)是(shi)截然不同(tong)(tong)的。由于零(ling)件(jian)的造型(xing)不同(tong)(tong)，很多情況下它們都(dou)要(yao)通(tong)過各種加(jia)工(gong)方式來加(jia)強它的質量和相(xiang)關的屬(shu)性功能。現如今的數控加(jia)工(gong)方式已經(jing)延伸到(dao)各種制造領域(yu)，其中CNC加(jia)工(gong)方式也(ye)是(shi)一種加(jia)強金屬(shu)產品的常用(yong)手段。隨著(zhu)技術的特點不斷地提升，它的加(jia)工(gong)質量也(ye)逐(zhu)漸地升級和改造。

CNC加(jia)(jia)工(gong)(gong)中壓(ya)(ya)(ya)(ya)(ya)鑄工(gong)(gong)藝就是(shi)利用機器、模具(ju)和合金(jin)(jin)(jin)等三(san)大要素，將(jiang)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)、速度(du)及時(shi)間統(tong)一的(de)(de)過程(cheng)。用于金(jin)(jin)(jin)屬熱加(jia)(jia)工(gong)(gong)，壓(ya)(ya)(ya)(ya)(ya)力(li)(li)的(de)(de)存在是(shi)壓(ya)(ya)(ya)(ya)(ya)鑄工(gong)(gong)藝區(qu)別(bie)其他(ta)鑄造(zao)方法(fa)的(de)(de)主要特點.。CNC加(jia)(jia)工(gong)(gong)的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)鑄造(zao)是(shi)近(jin)代(dai)金(jin)(jin)(jin)屬加(jia)(jia)工(gong)(gong)工(gong)(gong)藝中發展較快的(de)(de)一種少無切削的(de)(de)特種鑄造(zao)方法(fa)。它是(shi)將(jiang)熔融金(jin)(jin)(jin)屬在高壓(ya)(ya)(ya)(ya)(ya)高速下充填鑄型(xing)，并在高壓(ya)(ya)(ya)(ya)(ya)下結晶凝固形成(cheng)鑄件的(de)(de)過程(cheng)。高壓(ya)(ya)(ya)(ya)(ya)高速是(shi)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)鑄造(zao)的(de)(de)主要特征。常用的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)為(wei)數(shu)十兆帕，填充速度(du)（內澆口速度(du)）約為(wei)16～80米/秒，金(jin)(jin)(jin)屬液填充模具(ju)型(xing)腔的(de)(de)時(shi)間極短，約為(wei)0.01～0.2秒。

CNC加(jia)工(gong)(gong)中(zhong)(zhong)壓(ya)(ya)鑄(zhu)工(gong)(gong)藝(yi)是(shi)(shi)將壓(ya)(ya)鑄(zhu)機(ji)、壓(ya)(ya)鑄(zhu)模和(he)合(he)(he)(he)金(jin)三(san)大要(yao)素有(you)機(ji)地組合(he)(he)(he)而(er)加(jia)以綜(zong)合(he)(he)(he)運(yun)用的(de)(de)過(guo)(guo)程(cheng)。而(er)壓(ya)(ya)鑄(zhu)時(shi)金(jin)屬按填(tian)充型腔的(de)(de)過(guo)(guo)程(cheng)，是(shi)(shi)將壓(ya)(ya)力(li)、速度、溫度以及時(shi)間(jian)等工(gong)(gong)藝(yi)因素得(de)到統(tong)一的(de)(de)過(guo)(guo)程(cheng)。同時(shi)，這(zhe)些工(gong)(gong)藝(yi)因素又相(xiang)(xiang)互影響(xiang)，相(xiang)(xiang)互制(zhi)約，并且相(xiang)(xiang)輔相(xiang)(xiang)成。只有(you)正(zheng)確選擇和(he)調(diao)整這(zhe)些因素，使之協調(diao)一致(zhi)，才能獲得(de)預期的(de)(de)結(jie)果(guo)。因此，在CNC加(jia)工(gong)(gong)壓(ya)(ya)鑄(zhu)過(guo)(guo)程(cheng)中(zhong)(zhong)不僅要(yao)重(zhong)視(shi)鑄(zhu)件結(jie)構的(de)(de)工(gong)(gong)藝(yi)性(xing)，壓(ya)(ya)鑄(zhu)模的(de)(de)先進性(xing)，壓(ya)(ya)鑄(zhu)機(ji)性(xing)能和(he)結(jie)構優良性(xing)，壓(ya)(ya)鑄(zhu)合(he)(he)(he)金(jin)選用的(de)(de)適(shi)應性(xing)和(he)熔煉工(gong)(gong)藝(yi)的(de)(de)規范性(xing)；更應重(zhong)視(shi)壓(ya)(ya)力(li)、溫度和(he)時(shi)間(jian)等工(gong)(gong)藝(yi)參數對鑄(zhu)件質量的(de)(de)重(zhong)要(yao)作用。在壓(ya)(ya)鑄(zhu)過(guo)(guo)程(cheng)中(zhong)(zhong)應重(zhong)視(shi)對這(zhe)些參數進行有(you)效的(de)(de)控制(zhi)。
