尺(chi)寸規格(ge)較小(xiao)的(de)(de)升降臺式(shi)數控(kong)銑(xian)床,其工作臺寬度多在(zai)400mm以下(xia),它Z適宜中小(xiao)零件(jian)的(de)(de)加(jia)工和復雜形面的(de)(de)輪廓銑(xian)削任務(wu)。規格(ge)較大(da)的(de)(de)如龍(long)門(men)式(shi)銑(xian)床,工作臺在(zai)500-600mm以上(shang),用來解決(jue)大(da)尺(chi)寸復雜零件(jian)的(de)(de)加(jia)工需(xu)要(yao)。
精(jing)度我國已(yi)制定(ding)(ding)了數(shu)控(kong)銑(xian)床(chuang)的精(jing)度標(biao)(biao)準(zhun),其中數(shu)控(kong)立(li)式銑(xian)床(chuang)升降臺(tai)銑(xian)床(chuang)已(yi)有專業(ye)標(biao)(biao)準(zhun)。標(biao)(biao)準(zhun)規定(ding)(ding)其直線運(yun)動坐標(biao)(biao)的定(ding)(ding)位精(jing)度為0.04/300mm,重復定(ding)(ding)位精(jing)度為0.025mm,銑(xian)圓精(jing)0.035mm。實際上(shang),機床(chuang)出廠(chang)精(jing)度均有相當的儲備量,比國家標(biao)(biao)準(zhun)的允差值大(da)約(yue)壓(ya)縮(suo)20%左右。
因(yin)此,從精度選擇來(lai)看(kan),一般的(de)數(shu)控銑床即可滿足大多(duo)數(shu)零(ling)件的(de)加工需(xu)要(yao)。對(dui)于(yu)精度要(yao)求(qiu)比較(jiao)高的(de)零(ling)件,則應考(kao)慮選用(yong)精密(mi)型的(de)數(shu)控銑床。批(pi)(pi)量(liang)對(dui)于(yu)大批(pi)(pi)量(liang)的(de)物品,可采用(yong)專用(yong)銑床。如果是(shi)中小批(pi)(pi)量(liang)而又是(shi)經常周(zhou)期性重復投產(chan)(chan)的(de)話,那么采用(yong)數(shu)控銑床是(shi)非常合適的(de),因(yin)為第 一批(pi)(pi)量(liang)中準備好多(duo)工夾(jia)具、程序等可以(yi)存儲起來(lai)重復使用(yong)。從長遠考(kao)慮,自動化(hua)程度高的(de)銑床代替普(pu)通銑床,減輕勞(lao)動者(zhe)的(de)勞(lao)動量(liang)提高生產(chan)(chan)率(lv)的(de)趨(qu)勢是(shi)不(bu)可避免的(de)。
