模具加工是指成(cheng)型和(he)制(zhi)坯工具(ju)的(de)(de)加工，此(ci)外還包(bao)括(kuo)剪切(qie)模(mo)(mo)(mo)(mo)(mo)和(he)模(mo)(mo)(mo)(mo)(mo)切(qie)模(mo)(mo)(mo)(mo)(mo)具(ju)。 通常情況下(xia)，模(mo)(mo)(mo)(mo)(mo)具(ju)有上模(mo)(mo)(mo)(mo)(mo)和(he)下(xia)模(mo)(mo)(mo)(mo)(mo)兩(liang)部分組成(cheng)。將(jiang)鋼板放置(zhi)在上下(xia)模(mo)(mo)(mo)(mo)(mo)之(zhi)間，在壓(ya)力機(ji)的(de)(de)作用下(xia)實現材(cai)料的(de)(de)成(cheng)型，當壓(ya)力機(ji)打開時(shi)，就會獲(huo)得由模(mo)(mo)(mo)(mo)(mo)具(ju)形狀所(suo)確定(ding)的(de)(de)工件或去(qu)除相應(ying)的(de)(de)廢料。

  小至電子連接器，大至汽(qi)車儀表盤的工(gong)(gong)(gong)(gong)(gong)件都(dou)可以用模(mo)具(ju)(ju)(ju)(ju)成(cheng)型(xing)。 級進模(mo)是(shi)指(zhi)能自動的把加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)件從一個(ge)工(gong)(gong)(gong)(gong)(gong)位(wei)(wei)移動到(dao)另一個(ge)工(gong)(gong)(gong)(gong)(gong)位(wei)(wei)，并(bing)在最后一個(ge)工(gong)(gong)(gong)(gong)(gong)位(wei)(wei)得到(dao)成(cheng)型(xing)零件的一套模(mo)具(ju)(ju)(ju)(ju)。模(mo)具(ju)(ju)(ju)(ju)加工(gong)(gong)(gong)(gong)(gong)是(shi)指(zhi)成(cheng)型(xing)和制坯工(gong)(gong)(gong)(gong)(gong)具(ju)(ju)(ju)(ju)的加工(gong)(gong)(gong)(gong)(gong)，此外還包括剪切(qie)(qie)模(mo)和模(mo)切(qie)(qie)模(mo)具(ju)(ju)(ju)(ju)。

  通常情況下，大連模具加工有上(shang)(shang)模和下(xia)模兩部分組成。將鋼(gang)板放置在(zai)上(shang)(shang)下(xia)模之間，在(zai)壓力機的作用(yong)下(xia)實現材料(liao)的成型，當壓力機打(da)開(kai)時，就會獲(huo)得由模具形狀所確定的工(gong)件或去除相應的廢料(liao)。

  模(mo)具(ju)是目前應用(yong)數控加(jia)工(gong)(gong)最(zui)為(wei)廣泛的(de)(de)行業之一。隨著市場對模(mo)具(ju)產(chan)品質量(liang)要求的(de)(de)不斷(duan)提高，將有(you)更多的(de)(de)企業選用(yong)加(jia)工(gong)(gong)中心(xin)。加(jia)工(gong)(gong)中心(xin)的(de)(de)性(xing)能將直接(jie)影響模(mo)具(ju)的(de)(de)加(jia)工(gong)(gong)工(gong)(gong)藝、加(jia)工(gong)(gong)質量(liang)和生產(chan)效率。加(jia)工(gong)(gong)中心(xin)綜合(he)應用(yong)了機械技術(shu)(shu)、電子技術(shu)(shu)、計算機技術(shu)(shu)、電氣技術(shu)(shu)、液壓技術(shu)(shu)、光學(xue)技術(shu)(shu)，具(ju)有(you)先進(jin)性(xing)、復雜性(xing)，發展(zhan)的(de)(de)迅速性(xing)以及品種型號和檔次的(de)(de)多樣(yang)性(xing)，而且價格相(xiang)對比(bi)較昂貴。

  由(you)于模具材料均(jun)較硬，而(er)加(jia)工中(zhong)(zhong)心(xin)(xin)技(ji)術參(can)數說(shuo)明中(zhong)(zhong)標(biao)出的(de)精(jing)度(du)(du)，是加(jia)工中(zhong)(zhong)心(xin)(xin)在(zai)無(wu)負載下(xia)的(de)技(ji)術參(can)數。在(zai)實(shi)際加(jia)工狀態下(xia)的(de)精(jing)度(du)(du)還與加(jia)工中(zhong)(zhong)心(xin)(xin)的(de)剛性等因素有關(guan)，所以(yi)應對模具工業用加(jia)工中(zhong)(zhong)心(xin)(xin)的(de)剛性予以(yi)特別關(guan)注。
