cnc四(si)軸(zhou)加(jia)工中心最早運(yun)用(yong)于曲線曲面的加(jia)工，即(ji)葉(xie)片的加(jia)工。現往常(chang)，cnc四(si)軸(zhou)加(jia)工中心可以適(shi)用(yong)于多面體零件、帶(dai)回(hui)轉角度(du)的螺旋線（圓柱面油槽(cao)）、螺旋槽(cao)、圓柱面凸輪、擺線的加(jia)工等等，運(yun)用(yong)及其(qi)普(pu)遍(bian)。

　　從加(jia)(jia)(jia)(jia)工(gong)產品我(wo)們可以(yi)看(kan)出，cnc四(si)軸(zhou)(zhou)(zhou)加(jia)(jia)(jia)(jia)工(gong)有(you)以(yi)下特(te)征：由于有(you)旋轉軸(zhou)(zhou)(zhou)的參與，使無暇間曲面(mian)的加(jia)(jia)(jia)(jia)工(gong)成為可能(neng)，大(da)大(da)進步了自(zi)在(zai)空間曲面(mian)的加(jia)(jia)(jia)(jia)工(gong)精度、質(zhi)量和功率；三軸(zhou)(zhou)(zhou)加(jia)(jia)(jia)(jia)工(gong)機(ji)床無法加(jia)(jia)(jia)(jia)工(gong)到的或(huo)需求裝夾過長的工(gong)件（如長軸(zhou)(zhou)(zhou)類(lei)軸(zhou)(zhou)(zhou)面(mian)加(jia)(jia)(jia)(jia)工(gong)）的加(jia)(jia)(jia)(jia)工(gong)。

　　可以經(jing)過四軸旋轉工作臺結束，縮短裝夾時間，削減加工工序，盡(jin)可能地(di)經(jing)過一次定位停(ting)止多(duo)工序加工，削減定位過失；刀具(ju)得到(dao)很大(da)改(gai)善，延伸刀具(ju)壽數；有利(li)于出產集中(zhong)化。

　　cnc四軸(zhou)加(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心普通有兩(liang)種加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)式：定位加(jia)(jia)工(gong)(gong)(gong)(gong)和插補加(jia)(jia)工(gong)(gong)(gong)(gong)，分別對應(ying)多面體(ti)零件加(jia)(jia)工(gong)(gong)(gong)(gong)和回轉體(ti)歸(gui)結加(jia)(jia)工(gong)(gong)(gong)(gong)。如今，以帶(dai)A軸(zhou)為旋轉軸(zhou)的(de)四軸(zhou)加(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心為例，分別對兩(liang)種加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)式停止闡(chan)明。
