加工中心主軸技術(shu)含量很(hen)高，也(ye)是加工中心較重(zhong)要部件(jian)之(zhi)一(yi)，國(guo)內(nei)有(you)(you)能力生(sheng)產(chan)(chan)主軸的(de)廠家(jia)少之(zhi)又少，所以國(guo)內(nei)生(sheng)產(chan)(chan)電主軸轉速(su)沒有(you)(you)國(guo)外產(chan)(chan)電主軸的(de)轉速(su)高，且國(guo)產(chan)(chan)電主軸目前沒有(you)(you)能力采用空氣靜壓(ya)軸承(cheng)和磁浮(fu)軸承(cheng)，就算采用了也(ye)達不到這么高的(de)轉速(su)。
