二、數控鉆床簡介
數(shu)控(kong)(kong)(kong)(kong)鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)是用數(shu)控(kong)(kong)(kong)(kong)系統控(kong)(kong)(kong)(kong)制加工(gong)(gong)(gong)過程的鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)。它有(you)單(dan)工(gong)(gong)(gong)作(zuo)臺(tai)和雙工(gong)(gong)(gong)作(zuo)臺(tai)兩(liang)(liang)種形式,都是用數(shu)控(kong)(kong)(kong)(kong)進行點位(wei)、直線控(kong)(kong)(kong)(kong)制的,定位(wei)精度為±(0.02~0.1)mm。數(shu)控(kong)(kong)(kong)(kong)立(li)式鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)主(zhu)機類(lei)型主(zhu)要有(you)十字工(gong)(gong)(gong)作(zuo)臺(tai)立(li)式鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)、轉塔立(li)式鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)等。雙工(gong)(gong)(gong)作(zuo)臺(tai)的數(shu)控(kong)(kong)(kong)(kong)鉆(zhan)(zhan)(zhan)床(chuang)(chuang)(chuang)有(you)兩(liang)(liang)個可互(hu)相交替的工(gong)(gong)(gong)作(zuo)臺(tai),能將機動(dong)時間(jian)與裝卸(xie)工(gong)(gong)(gong)件的輔助時間(jian)重(zhong)疊(die)起來,提高(gao)機床(chuang)(chuang)(chuang)效率。
數(shu)控(kong)鉆(zhan)床(chuang)應用(yong)(yong)范圍也較廣,在IT行(xing)業中(zhong),印(yin)制電路(lu)(lu)板(ban)數(shu)控(kong)鉆(zhan)床(chuang)有(you)2~4根主軸,用(yong)(yong)于對單面(mian)、雙(shuang)面(mian)或多(duo)層印(yin)制電路(lu)(lu)板(ban)進行(xing)小孔鉆(zhan)削加(jia)工(gong)。國外(wai)對一些(xie)大(da)型工(gong)件(jian)(大(da)型水電站(zhan)水輪機葉片)的粗加(jia)工(gong),也先采用(yong)(yong)數(shu)控(kong)鉆(zhan)床(chuang)進行(xing)矩陣式密集鉆(zhan)削,迅速去(qu)掉大(da)量加(jia)工(gong)余量;再用(yong)(yong)加(jia)工(gong)中(zhong)心進行(xing)銑削成形,以降低加(jia)工(gong)成本。
三、數控鉆床(chuang)有哪些優勢
1、為(wei)使之(zhi)有足(zu)夠的剛性(xing)與(yu)穩(wen)定性(xing),避免(mian)微小的震動,大(da)都采用笨重的大(da)理(li)石機(ji)身。
2、X、y分離使數控機床(chuang)質量減輕(qing),速度提高(gao),穩定性增強(qiang)。
3、多主(zhu)軸(zhou)的機器每個Z軸(zhou)都采用單獨驅動。
4、由直流(liu)伺服馬達驅(qu)動向交流(liu)伺服馬達驅(qu)動發展。使之(zhi)動力更(geng)強,工作臺(tai)運行速度更(geng)快(kuai)。
5、位(wei)置精(jing)度測(ce)量(liang)與反饋系統由磁尺向光(guang)柵發(fa)展,其分辨率高且穩(wen)定。
6、X、Y導(dao)向逐漸由滾動導(dao)軌代替氣(qi)浮導(dao)向的趨勢。其穩定性(xing)好,剛性(xing)好。
7、鉆的(de)主(zhu)軸大都采用(yong)空氣軸承,高轉速主(zhu)軸,鉆速達(1.5~16)×104r/rain可以(yi)使用(yong)的(de)刀具直(zhi)徑范圍婦14—9168mm。
8、刀具(ju)庫管(guan)理(li)系統包括自(zi)動換鉆,斷刀自(zi)動檢測(ce)系統。
9、具有排鉆(zhan)功(gong)能(neng),能(neng)以鉆(zhan)代銑(xian)。
10、具(ju)有鉆深控制功(gong)能,能鉆盲(mang)孔。
11、具有分布鉆孔功能,能鉆深孔,孔徑深度比為(1:lo)~(1:20)。 //xcmag.cn/
