SP1840龍(long)(long)門(men)加(jia)工(gong)(gong)(gong)中(zhong)心主要應用于重(zhong)工(gong)(gong)(gong)業行業，比如(ru)飛(fei)(fei)機、汽車(che)、船舶(bo)等(deng)(deng)重(zhong)型行業中(zhong)，主要加(jia)工(gong)(gong)(gong)大型復(fu)雜(za)形狀的(de)工(gong)(gong)(gong)件，比如(ru)加(jia)工(gong)(gong)(gong)飛(fei)(fei)機的(de)梁、框以及大型機械(xie)上的(de)某些零(ling)件等(deng)(deng)。龍(long)(long)門(men)加(jia)工(gong)(gong)(gong)中(zhong)心的(de)龍(long)(long)門(men)架(jia)(jia)由兩(liang)個立柱(zhu)、橫梁、滑(hua)鞍(an)等(deng)(deng)部件組(zu)成，根據龍(long)(long)門(men)架(jia)(jia)可為(wei)定梁式(shi)、動(dong)(dong)(dong)梁式(shi)和(he)動(dong)(dong)(dong)柱(zhu)式(shi)。頂梁式(shi)的(de)橫梁固(gu)定，工(gong)(gong)(gong)作臺(tai)(tai)移動(dong)(dong)(dong)；動(dong)(dong)(dong)梁式(shi)的(de)橫梁上下移動(dong)(dong)(dong)，工(gong)(gong)(gong)作臺(tai)(tai)誠前后(hou)移動(dong)(dong)(dong)；動(dong)(dong)(dong)柱(zhu)式(shi)工(gong)(gong)(gong)作臺(tai)(tai)固(gu)定，龍(long)(long)門(men)架(jia)(jia)移動(dong)(dong)(dong)。

　　主要特點有：

　　（1）在數控鏜床或數控能(neng)床的基(ji)礎上增加自(zi)內換刀裝置(zhi)，使工(gong)件在一-次(ci)裝夾后，可以連(lian)續完成對工(gong)件表面多工(gong)序的加工(gong)，工(gong)序高度集中。

　　（2）一(yi)般(ban)帶有(you)自動分(fen)度(du)回轉作臺(tai)或主軸箱，可自動轉角度(du)，從而使工(gong)件一(yi)次裝夾后自動完成多個(ge)平(ping)面或多個(ge)角度(du)位(wei)置的多工(gong)序加工(gong)。

　　（3）能自(zi)動改變機床(chuang)主(zhu)軸轉速、進給量和刀具相對工件的運動軌跡及其他輔(fu)助(zhu)機能。

　　（4）如果帶有交換作臺，工件在工作位置的工作臺進行加工的同時，另外的工件在裝卸位置的工作臺上進行裝卸不影響正常的加工工件。
