高速(su)加工中(zhong)心電主軸的轉速(su)
高速(su)(su)加工中心不(bu)管(guan)采(cai)(cai)用(yong)(yong)什么(me)主(zhu)(zhu)(zhu)軸的(de)轉(zhuan)(zhuan)(zhuan)速(su)(su)都是(shi)在12000r/min以(yi)(yi)上的(de)，采(cai)(cai)用(yong)(yong)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸的(de)高速(su)(su)加工中心的(de)轉(zhuan)(zhuan)(zhuan)速(su)(su)較少(shao)在18000r/min以(yi)(yi)上，由(you)于電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸采(cai)(cai)用(yong)(yong)的(de)軸承(cheng)(cheng)(cheng)會影響轉(zhuan)(zhuan)(zhuan)速(su)(su)，所以(yi)(yi)采(cai)(cai)用(yong)(yong)不(bu)同(tong)(tong)的(de)軸承(cheng)(cheng)(cheng)的(de)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸的(de)轉(zhuan)(zhuan)(zhuan)速(su)(su)就不(bu)同(tong)(tong)。一般(ban)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸采(cai)(cai)用(yong)(yong)的(de)軸承(cheng)(cheng)(cheng)有三種(zhong)，分別是(shi)陶瓷球(qiu)軸承(cheng)(cheng)(cheng)、空(kong)(kong)氣(qi)靜壓軸承(cheng)(cheng)(cheng)和磁浮(fu)軸承(cheng)(cheng)(cheng)這三種(zhong)。采(cai)(cai)用(yong)(yong)陶瓷球(qiu)軸承(cheng)(cheng)(cheng)的(de)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸的(de)轉(zhuan)(zhuan)(zhuan)速(su)(su)一般(ban)在18000-40000r/min之間；采(cai)(cai)用(yong)(yong)磁浮(fu)軸承(cheng)(cheng)(cheng)的(de)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸的(de)轉(zhuan)(zhuan)(zhuan)速(su)(su)在100000r/min；采(cai)(cai)用(yong)(yong)空(kong)(kong)氣(qi)靜壓軸承(cheng)(cheng)(cheng)的(de)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸轉(zhuan)(zhuan)(zhuan)速(su)(su)可以(yi)(yi)達到160000r/min；由(you)此(ci)可見，采(cai)(cai)用(yong)(yong)不(bu)同(tong)(tong)軸承(cheng)(cheng)(cheng)的(de)電(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸轉(zhuan)(zhuan)(zhuan)速(su)(su)就不(bu)同(tong)(tong)。
加工中心(xin)主軸(zhou)技(ji)術含量很高，也是加工中心(xin)較重要部件(jian)之一，國內(nei)(nei)有能力生產(chan)主軸(zhou)的廠家少之又少，所以國內(nei)(nei)生產(chan)電主軸(zhou)轉速沒(mei)(mei)有國外產(chan)電主軸(zhou)的轉速高，且國產(chan)電主軸(zhou)目前沒(mei)(mei)有能力采(cai)用(yong)空氣(qi)靜(jing)壓軸(zhou)承和磁(ci)浮軸(zhou)承，就(jiu)算采(cai)用(yong)了也達不到這么高的轉速。
