立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)是指主軸軸線與(yu)(yu)工(gong)(gong)作臺垂直(zhi)設置的(de)加(jia)工(gong)(gong)中(zhong)心(xin)，主要(yao)適用于加(jia)工(gong)(gong)板類(lei)(lei)(lei)、盤(pan)類(lei)(lei)(lei)、模具及小型殼體類(lei)(lei)(lei)復雜(za)零件(jian)(jian)。立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)能(neng)完成銑、鏜削、鉆削、攻螺紋和用切削螺紋等工(gong)(gong)序。立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)少是三軸二聯動(dong)，般可(ke)(ke)實現(xian)三軸三聯動(dong)。有的(de)可(ke)(ke)進(jin)行五(wu)軸、六(liu)軸控制。立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)立(li)柱高度是有限的(de)，對箱體類(lei)(lei)(lei)工(gong)(gong)件(jian)(jian)加(jia)工(gong)(gong)范圍要(yao)減少，這是立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)的(de)缺點。但立(li)式加(jia)工(gong)(gong)中(zhong)心(xin)工(gong)(gong)件(jian)(jian)裝夾、定位方便；刃(ren)具運動(dong)軌跡易觀察，調試程序檢查測量方便，可(ke)(ke)及時發現(xian)問(wen)題，進(jin)行停機處理或修改；冷卻條件(jian)(jian)易建立(li)，切削液(ye)能(neng)直(zhi)接到(dao)達刀具和加(jia)工(gong)(gong)表(biao)面(mian)；三個坐標(biao)軸與(yu)(yu)笛卡兒坐標(biao)系吻合(he)，感覺(jue)直(zhi)觀與(yu)(yu)圖(tu)樣視角致(zhi)，切屑易排(pai)除和掉落，避免劃傷(shang)加(jia)工(gong)(gong)過的(de)表(biao)面(mian)。與(yu)(yu)相(xiang)(xiang)應的(de)臥式加(jia)工(gong)(gong)中(zhong)心(xin)相(xiang)(xiang)比，結構簡單，占地面(mian)積(ji)較(jiao)小，價格較(jiao)低。
立式與臥式的區別
立式
立式加(jia)工(gong)中(zhong)(zhong)心(xin)是(shi)指主軸為垂(chui)直狀(zhuang)態的加(jia)工(gong)中(zhong)(zhong)心(xin)，其結構形式多為固定立柱，工(gong)作(zuo)臺(tai)為長方形，無(wu)分(fen)度回(hui)轉(zhuan)功能(neng)，適合(he)加(jia)工(gong)盤、套、板類零件，它般具有三個直線運動坐標軸，并可在工(gong)作(zuo)臺(tai)上安裝個沿水平軸旋轉(zhuan)的回(hui)轉(zhuan)臺(tai)，用以加(jia)工(gong)螺旋線類零件。
立(li)式加(jia)(jia)工(gong)(gong)(gong)中心裝卡(ka)方(fang)便，便于操作，易(yi)于觀(guan)察加(jia)(jia)工(gong)(gong)(gong)情況，調試(shi)程序容(rong)易(yi)，應用廣泛。但受立(li)柱高度及換(huan)刀裝置(zhi)的(de)限制，不能加(jia)(jia)工(gong)(gong)(gong)太高的(de)零件，在(zai)加(jia)(jia)工(gong)(gong)(gong)型腔或下凹的(de)型面時，切屑不易(yi)排出(chu)，嚴重時會損壞刀具(ju)，破壞已加(jia)(jia)工(gong)(gong)(gong)表面，影響(xiang)加(jia)(jia)工(gong)(gong)(gong)的(de)順利進行(xing)。
臥(wo)式
臥式(shi)加工(gong)(gong)中心(xin)指主(zhu)軸為水平狀態的(de)加工(gong)(gong)中心(xin)，通常都帶有(you)自動(dong)分度的(de)回轉工(gong)(gong)作臺，它般具(ju)有(you)3～5個運動(dong)坐標，常見(jian)的(de)是(shi)三個直線運動(dong)坐標加個回轉運動(dong)坐標， 工(gong)(gong)件(jian)(jian)在次(ci)裝卡(ka)后(hou)，完成(cheng)除安裝面(mian)和頂(ding)面(mian)以外的(de)其余四個表(biao)面(mian)的(de)加工(gong)(gong)，它適合(he)加上箱體(ti)類(lei)零件(jian)(jian)。與(yu)立式(shi)加工(gong)(gong)中心(xin)相比較，臥式(shi)加工(gong)(gong)中心(xin)加工(gong)(gong)時排(pai)屑容易，對加工(gong)(gong)有(you) 利(li)，但結構(gou)復雜．價格較高
