最簡單(dan)(dan)的(de)(de)(de)答案是因為生產力和利潤(run)。雙(shuang)主軸(zhou)加(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)心可以(yi)輕(qing)松(song)完(wan)成同類(lei)單(dan)(dan)主軸(zhou)加(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)心的(de)(de)(de)二倍工(gong)(gong)(gong)(gong)作量(liang)(liang)。假定保(bao)持機(ji)(ji)器(qi)忙碌的(de)(de)(de)工(gong)(gong)(gong)(gong)作負載(zai)是可用(yong)的(de)(de)(de)。毫(hao)無(wu)疑(yi)問，制(zhi)造商(shang)可以(yi)使用(yong) 雙(shuang)主軸(zhou)加(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)心 在更(geng)短的(de)(de)(de)時間內完(wan)成更(geng)多零件加(jia)(jia)工(gong)(gong)(gong)(gong)。隨著產量(liang)(liang)的(de)(de)(de)增(zeng)加(jia)(jia)，車間的(de)(de)(de)吞吐量(liang)(liang)大(da)大(da)提高。同時加(jia)(jia)工(gong)(gong)(gong)(gong)兩個工(gong)(gong)(gong)(gong)件，只占(zhan)用(yong)一臺機(ji)(ji)器(qi)的(de)(de)(de)場地和一名cnc操作員，變相的(de)(de)(de)增(zeng)加(jia)(jia)了廠房(fang)機(ji)(ji)器(qi)數量(liang)(liang)減少了人工(gong)(gong)(gong)(gong)成本并且提高效率。

　　在手機(ji)通訊、電(dian)子3C、新能源電(dian)池正負極等(deng)行業中(zhong)(zhong)，一名cnc操作員可(ke)以完(wan)成多名cnc操作員的(de)工(gong)作，從而降低(di)了勞動力成本(ben)。雖然一臺雙(shuang)主軸加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心比普通的(de)機(ji)床(chuang)的(de)費(fei)用高很多，但是一臺雙(shuang)主軸加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心的(de)高產量(liang)、高效率、低(di)勞動成本(ben)是遠遠優于普通單主軸加(jia)(jia)(jia)工(gong)中(zhong)(zhong)心的(de)。
