為什么cnc立式加工中心貴呢？

1.數控系統

CNC零件加工中心廠家(jia)數(shu)(shu)(shu)控(kong)系(xi)(xi)統可(ke)以說是(shi)價格(ge)差距大(da)的核心部(bu)件。進口(kou)(kou)數(shu)(shu)(shu)控(kong)系(xi)(xi)統價格(ge)較(jiao)(jiao)高，國產數(shu)(shu)(shu)控(kong)系(xi)(xi)統價格(ge)較(jiao)(jiao)低。目(mu)前，市場上(shang)進口(kou)(kou)系(xi)(xi)統泛亞(ya)科、三菱、西(xi)門子較(jiao)(jiao)為普(pu)遍。需要(yao)指出的是(shi)，進口(kou)(kou)系(xi)(xi)統通常是(shi)捆綁(bang)三軸伺服電機，此外，在(zai)加工要(yao)求低、資金預算有限的情況(kuang)下，可(ke)選用國產數(shu)(shu)(shu)控(kong)系(xi)(xi)統。

2.主軸單元

主(zhu)軸(zhou)單元(yuan)整(zheng)個(ge)設(she)備關鍵部件(jian)的(de)價格一般(ban)取(qu)決于(yu)兩點，一是(shi)設(she)備的(de)速度(du)，二是(shi)冷卻方(fang)式(shi)。 市場上普通加工(gong)(gong)中(zhong)心的(de)速度(du)一般(ban)為(wei)(wei)8000 RPM，可以根據實際(ji)加工(gong)(gong)需求提高或降低(di)。 主(zhu)軸(zhou)轉速不(bu)(bu)同(tong)，價格不(bu)(bu)同(tong)。 冷卻設(she)備也是(shi)主(zhu)軸(zhou)必(bi)(bi)不(bu)(bu)可少(shao)的(de)部分。 設(she)備在高速處(chu)理過程中(zhong)會(hui)產生大量熱(re)量。 工(gong)(gong)作臺和工(gong)(gong)件(jian)表面上的(de)高切屑的(de)熱(re)量不(bu)(bu)僅會(hui)影響工(gong)(gong)件(jian)的(de)加工(gong)(gong)精度(du)，還會(hui)損壞設(she)備。 冷卻系統是(shi)必(bi)(bi)不(bu)(bu)可少(shao)的(de)，通常分為(wei)(wei)水冷卻和油(you)冷卻。

3.刀具庫

CNC龍門加工中心，當我們編寫數控程序并調試主軸轉速時，我們將開(kai)始下一步的(de)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)作。加(jia)工(gong)(gong)(gong)中心(xin)的(de)工(gong)(gong)(gong)作部件也應放(fang)在工(gong)(gong)(gong)作臺上(shang)，即工(gong)(gong)(gong)具(ju)(ju)(ju)庫上(shang)。刀(dao)(dao)(dao)具(ju)(ju)(ju)庫是(shi)加(jia)工(gong)(gong)(gong)中心(xin)存(cun)放(fang)刀(dao)(dao)(dao)具(ju)(ju)(ju)的(de)容器，刀(dao)(dao)(dao)具(ju)(ju)(ju)是(shi)直(zhi)接對工(gong)(gong)(gong)件進行鉆孔、銑(xian)削和切割的(de)零件。常用工(gong)(gong)(gong)具(ju)(ju)(ju)倉庫分為盤(pan)類工(gong)(gong)(gong)具(ju)(ju)(ju)倉庫和帽類工(gong)(gong)(gong)具(ju)(ju)(ju)倉庫。刀(dao)(dao)(dao)具(ju)(ju)(ju)庫的(de)價(jia)格差異反映在刀(dao)(dao)(dao)具(ju)(ju)(ju)更換(huan)的(de)數量和速度上(shang)。盤(pan)刀(dao)(dao)(dao)庫設(she)有機械(xie)手，可在3秒內完成換(huan)刀(dao)(dao)(dao)操作。又稱機械(xie)手刀(dao)(dao)(dao)具(ju)(ju)(ju)庫。
