數控(kong)銑(xian)削加工(gong)(gong)除了具有(you)普通銑(xian)床加工(gong)(gong)的特(te)點(dian)外，還(huan)有(you)如下特(te)點(dian)：

1、零(ling)件(jian)加工(gong)(gong)的適應(ying)性強、靈(ling)活性好，能加工(gong)(gong)輪(lun)廓形狀特別復雜或(huo)難以控(kong)制尺(chi)寸的零(ling)件(jian)，如模具類(lei)零(ling)件(jian)、殼體類(lei)零(ling)件(jian)等；

2、能加(jia)工普通機(ji)床無法(fa)加(jia)工或很難(nan)加(jia)工的零(ling)件(jian)，如用(yong)數學模型(xing)描述的復雜曲(qu)線(xian)零(ling)件(jian)以及三(san)維空(kong)間曲(qu)面類零(ling)件(jian)；

3、能(neng)加工(gong)一(yi)次裝夾(jia)定位后，需(xu)進行多道工(gong)序加工(gong)的零件；

4、加(jia)(jia)工(gong)(gong)精度高、加(jia)(jia)工(gong)(gong)質量(liang)穩定可靠(kao)，數(shu)控(kong)裝(zhuang)置的脈沖當量(liang)一般為0.001mm，高精度的數(shu)控(kong)系統可達0.1μm，另外，數(shu)控(kong)加(jia)(jia)工(gong)(gong)還避免了操(cao)作人員的操(cao)作失(shi)誤；

5、自(zi)(zi)動化程度高，可以(yi)減(jian)輕操作者的勞動強(qiang)度。有利于管理自(zi)(zi)動化；

6、效率(lv)高，數(shu)控(kong)(kong)銑(xian)床一般不需要使(shi)用(yong)(yong)專(zhuan)用(yong)(yong)夾具等專(zhuan)用(yong)(yong)工(gong)(gong)(gong)藝(yi)設備(bei)，在更換工(gong)(gong)(gong)件(jian)時只需調(diao)(diao)用(yong)(yong)存儲于數(shu)控(kong)(kong)裝(zhuang)置中的加工(gong)(gong)(gong)程(cheng)序、裝(zhuang)夾工(gong)(gong)(gong)具和調(diao)(diao)整刀具數(shu)據(ju)即可(ke)，因而大(da)大(da)縮(suo)短了周期。其次(ci)，數(shu)控(kong)(kong)銑(xian)床具有銑(xian)床、鏜床、鉆床的功能，使(shi)工(gong)(gong)(gong)序高度集中，大(da)大(da)提高了效率(lv)。另外，數(shu)控(kong)(kong)銑(xian)床的主軸轉速(su)(su)和進給速(su)(su)度都是無(wu)級(ji)變速(su)(su)的，因此有利于選擇切削(xue)用(yong)(yong)量(liang)；
