高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)顧名思義(yi)高(gao)(gao)速(su)(su)(su)切(qie)削(xue)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)速(su)(su)(su)度(du)是(shi)(shi)常規(gui)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)的(de)(de)(de)5-10倍(bei)的(de)(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)就稱為高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)，這類加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)主要注(zhu)重的(de)(de)(de)是(shi)(shi)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)效率和精度(du)。高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)是(shi)(shi)否能進行高(gao)(gao)速(su)(su)(su)切(qie)削(xue)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)取決于于主軸(zhou)的(de)(de)(de)回轉(zhuan)速(su)(su)(su)度(du)和三軸(zhou)的(de)(de)(de)給(gei)進速(su)(su)(su)度(du)，其主軸(zhou)回轉(zhuan)速(su)(su)(su)度(du)和三軸(zhou)給(gei)進速(su)(su)(su)度(du)越高(gao)(gao)速(su)(su)(su)切(qie)削(xue)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)速(su)(su)(su)度(du)就越快。加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)速(su)(su)(su)度(du)主要影響源于主軸(zhou)和三軸(zhou)（XYZ），今天小編就來介紹一下高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)的(de)(de)(de)主軸(zhou)，高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)一般都是(shi)(shi)采用直結(jie)式(shi)主軸(zhou)和電主軸(zhou)，其中(zhong)(zhong)使用電主軸(zhou)的(de)(de)(de)高(gao)(gao)速(su)(su)(su)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)(xin)(xin)(xin)較多。

高速加(jia)工中(zhong)心電主軸的轉速
高(gao)速(su)加(jia)工(gong)中心(xin)(xin)不(bu)(bu)管采(cai)用(yong)什么主(zhu)(zhu)(zhu)軸(zhou)的(de)(de)(de)(de)(de)轉(zhuan)速(su)都是在(zai)12000r/min以上的(de)(de)(de)(de)(de)，采(cai)用(yong)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)的(de)(de)(de)(de)(de)高(gao)速(su)加(jia)工(gong)中心(xin)(xin)的(de)(de)(de)(de)(de)轉(zhuan)速(su)較少(shao)在(zai)18000r/min以上，由于電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)采(cai)用(yong)的(de)(de)(de)(de)(de)軸(zhou)承(cheng)會影(ying)響轉(zhuan)速(su)，所以采(cai)用(yong)不(bu)(bu)同(tong)的(de)(de)(de)(de)(de)軸(zhou)承(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)的(de)(de)(de)(de)(de)轉(zhuan)速(su)就(jiu)不(bu)(bu)同(tong)。一般電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)采(cai)用(yong)的(de)(de)(de)(de)(de)軸(zhou)承(cheng)有三種，分別是陶瓷球(qiu)(qiu)軸(zhou)承(cheng)、空氣靜壓(ya)軸(zhou)承(cheng)和磁浮軸(zhou)承(cheng)這三種。采(cai)用(yong)陶瓷球(qiu)(qiu)軸(zhou)承(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)的(de)(de)(de)(de)(de)轉(zhuan)速(su)一般在(zai)18000-40000r/min之間；采(cai)用(yong)磁浮軸(zhou)承(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)的(de)(de)(de)(de)(de)轉(zhuan)速(su)在(zai)100000r/min；采(cai)用(yong)空氣靜壓(ya)軸(zhou)承(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)轉(zhuan)速(su)可以達到160000r/min；由此可見，采(cai)用(yong)不(bu)(bu)同(tong)軸(zhou)承(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)主(zhu)(zhu)(zhu)軸(zhou)轉(zhuan)速(su)就(jiu)不(bu)(bu)同(tong)。
加(jia)工(gong)中(zhong)心(xin)主軸(zhou)技術(shu)含(han)量(liang)很高(gao)，也是加(jia)工(gong)中(zhong)心(xin)較(jiao)重要(yao)部件之一，國內(nei)有能力生產(chan)主軸(zhou)的廠家(jia)少(shao)之又少(shao)，所以國內(nei)生產(chan)電(dian)主軸(zhou)轉(zhuan)速沒有國外產(chan)電(dian)主軸(zhou)的轉(zhuan)速高(gao)，且國產(chan)電(dian)主軸(zhou)目前沒有能力采(cai)用空氣靜壓軸(zhou)承(cheng)和磁浮軸(zhou)承(cheng)，就(jiu)算采(cai)用了也達(da)不到這么高(gao)的轉(zhuan)速。
