加工中心主(zhu)(zhu)軸(zhou)(zhou)(zhou)技(ji)術(shu)含量很高(gao)，也是加工中心較重要部件之(zhi)一，國內(nei)有能力生產(chan)(chan)主(zhu)(zhu)軸(zhou)(zhou)(zhou)的(de)(de)廠家(jia)少(shao)之(zhi)又少(shao)，所以(yi)國內(nei)生產(chan)(chan)電(dian)主(zhu)(zhu)軸(zhou)(zhou)(zhou)轉速(su)沒(mei)有國外產(chan)(chan)電(dian)主(zhu)(zhu)軸(zhou)(zhou)(zhou)的(de)(de)轉速(su)高(gao)，且國產(chan)(chan)電(dian)主(zhu)(zhu)軸(zhou)(zhou)(zhou)目前(qian)沒(mei)有能力采用空氣靜(jing)壓軸(zhou)(zhou)(zhou)承和磁(ci)浮軸(zhou)(zhou)(zhou)承，就算(suan)采用了也達不到這么高(gao)的(de)(de)轉速(su)。
