我們(men)一起來了(le)解下銑刀(dao)的使用特性。
1、銑(xian)(xian)削方式不(bu)(bu)同,根據(ju)不(bu)(bu)同的加工(gong)條(tiao)件,為(wei)了提高刀具的耐用(yong)度和生產率,可以選著不(bu)(bu)同的銑(xian)(xian)削方式,比如有逆銑(xian)(xian),順銑(xian)(xian)還有對稱(cheng)銑(xian)(xian)和不(bu)(bu)對稱(cheng)銑(xian)(xian)。
2、相繼切(qie)削(xue)銑(xian)(xian)(xian)(xian)削(xue)的(de)時(shi)候(hou)每個刀齒都是(shi)(shi)在(zai)繼續進行切(qie)削(xue),尤其是(shi)(shi)端(duan)銑(xian)(xian)(xian)(xian),銑(xian)(xian)(xian)(xian)削(xue)刀的(de)波動(dong)比較(jiao)大,因此震(zhen)動(dong)是(shi)(shi)不可避免的(de)。在(zai)震(zhen)動(dong)的(de)時(shi)候(hou)頻(pin)率(lv)和機(ji)床的(de)固有頻(pin)率(lv)想(xiang)同或者(zhe)是(shi)(shi)成倍數的(de)時(shi)候(hou),震(zhen)動(dong)是(shi)(shi)比較(jiao)嚴重的(de)。還(huan)有就(jiu)是(shi)(shi)在(zai)高速銑(xian)(xian)(xian)(xian)刀刀具還(huan)需要經常手動(dong)周期的(de)的(de)冷熱沖擊,比較(jiao)容易出現(xian)裂紋和崩(beng)刀,使得耐用性下降。
3、多刀(dao)多刃(ren)(ren)切削,銑刀(dao)的(de)吃比較多,切削刃(ren)(ren)的(de)總(zong)長度大,有利于提高刀(dao)具的(de)耐(nai)用度和生產生產率,有許多優點。但是(shi)(shi)這僅存在這兩個方面。一是(shi)(shi)刀(dao)齒(chi)容易出現徑(jing)向跳動,這將造成刀(dao)齒(chi)負荷(he)不(bu)等,磨(mo)損不(bu)均勻,影響已(yi)加工(gong)表面質量;二是(shi)(shi)刀(dao)齒(chi)的(de)容屑空(kong)間必須足(zu)夠,否則會損壞(huai)刀(dao)齒(chi)。
4、生產(chan)率高(gao)銑(xian)削時銑(xian)刀(dao)連續轉動,并且(qie)允許較高(gao)的(de)銑(xian)削速(su)度,因此具有較高(gao)的(de)生產(chan)率。銑(xian)刀(dao)的(de)使用(yong)特性
市場上按照銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao)的(de)種類可劃分為(wei)很多種,例如:合金銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),合金鉆(zhan)(zhan)(zhan)頭,合金鉸刀(dao)(dao)(dao)(dao),不等(deng)分銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),玉米銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),鑼刀(dao)(dao)(dao)(dao),鋁用銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),粗皮銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),波刃銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),微徑銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),微徑球(qiu)刀(dao)(dao)(dao)(dao),鋸(ju)片(pian)銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),鋸(ju)片(pian),定心(xin)鉆(zhan)(zhan)(zhan),麻花鉆(zhan)(zhan)(zhan),內(nei)冷鉆(zhan)(zhan)(zhan),臺階鉆(zhan)(zhan)(zhan),鉆(zhan)(zhan)(zhan)鉸刀(dao)(dao)(dao)(dao),直槽鉆(zhan)(zhan)(zhan),非標刀(dao)(dao)(dao)(dao)具,成型刀(dao)(dao)(dao)(dao),石墨專用刀(dao)(dao)(dao)(dao),高硬度銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao),等(deng)等(deng),對于不同的(de)銑(xian)(xian)(xian)刀(dao)(dao)(dao)(dao)他(ta)們的(de)特性都是(shi)大致相同的(de)。
