數控(kong)(kong)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心添加(jia)(jia)(jia)第(di)四軸(zhou)的(de)益處(chu)是能(neng)(neng)夠(gou)使(shi)刀具加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)的(de)平(ping)面更為(wei)普(pu)遍，并且能(neng)(neng)夠(gou)減少工(gong)(gong)(gong)(gong)件(jian)的(de)重復裝(zhuang)(zhuang)夾，進(jin)步工(gong)(gong)(gong)(gong)件(jian)的(de)整體加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度，利(li)于簡化工(gong)(gong)(gong)(gong)藝，進(jin)步消費效率。詳細說來，第(di)四軸(zhou)就是指的(de)是加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心數控(kong)(kong)分度頭，它能(neng)(neng)夠(gou)完成三軸(zhou)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心不(bu)能(neng)(neng)一次性(xing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)完成的(de)任務，它經過旋轉能(neng)(neng)夠(gou)使(shi)產(chan)品完成多面的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，大(da)大(da)進(jin)步了加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)效率，減少了裝(zhuang)(zhuang)夾次數。

　　數控加工(gong)(gong)(gong)(gong)中(zhong)心(xin)(xin)添加第四軸(zhou)(zhou)，能夠使刀具(ju)加工(gong)(gong)(gong)(gong)的(de)平面變得普(pu)(pu)遍(bian)，并且能夠減少(shao)工(gong)(gong)(gong)(gong)件(jian)的(de)重復裝夾，進(jin)步工(gong)(gong)(gong)(gong)件(jian)的(de)整體加工(gong)(gong)(gong)(gong)精度，利于簡化工(gong)(gong)(gong)(gong)藝(yi)，進(jin)步消費效(xiao)率。縮短(duan)消費時間，所以(yi)很多企業(ye)都需求用到四軸(zhou)(zhou)加工(gong)(gong)(gong)(gong)中(zhong)心(xin)(xin)，三軸(zhou)(zhou)即(ji)XYZ三個(ge)直線挪動坐標，第四軸(zhou)(zhou)普(pu)(pu)通一個(ge)旋轉軸(zhou)(zhou)，能夠使刀具(ju)與工(gong)(gong)(gong)(gong)件(jian)之間產(chan)生(sheng)角度偏移，即(ji)刀軸(zhou)(zhou)與工(gong)(gong)(gong)(gong)件(jian)外(wai)表法線成一個(ge)角度，擴展加工(gong)(gong)(gong)(gong)的(de)范圍。

　　在承(cheng)接外加(jia)工(gong)(gong)(gong)任務時(shi)，除了(le)要在數控(kong)機(ji)(ji)床(chuang)(chuang)上停止正常的(de)輪廓、孔的(de)加(jia)工(gong)(gong)(gong)，有時(shi)還需求加(jia)工(gong)(gong)(gong)曲(qu)線、曲(qu)面類零件，而這些加(jia)工(gong)(gong)(gong)在普通(tong)的(de)三坐標數控(kong)機(ji)(ji)床(chuang)(chuang)上是很(hen)難(nan)完(wan)成的(de)，此(ci)時(shi)能夠(gou)在數控(kong)機(ji)(ji)床(chuang)(chuang)上裝(zhuang)(zhuang)置(zhi)(zhi)第(di)(di)四軸，擴展機(ji)(ji)床(chuang)(chuang)功用(yong)，使本錢投入大幅降低。在三軸數控(kong)加(jia)工(gong)(gong)(gong)中(zhong)(zhong)心(xin)工(gong)(gong)(gong)作(zuo)臺(tai)上裝(zhuang)(zhuang)置(zhi)(zhi)數控(kong)分度頭作(zuo)為第(di)(di)四軸，經過此(ci)種改造(zao)，不(bu)只能把(ba)在數控(kong)機(ji)(ji)床(chuang)(chuang)上需求多道工(gong)(gong)(gong)序的(de)加(jia)工(gong)(gong)(gong)集中(zhong)(zhong)在一次(ci)裝(zhuang)(zhuang)置(zhi)(zhi)中(zhong)(zhong)完(wan)成，增加(jia)了(le)機(ji)(ji)床(chuang)(chuang)的(de)自在度，擴展其(qi)功用(yong)，而且(qie)進步了(le)加(jia)工(gong)(gong)(gong)精度、質量和效益(yi)。
