深孔鉆鏜床是鏜床的一種。它(ta)有三種工作形式：

1.工件旋轉、刀具旋轉和往復進給運動，適用(yong)于鉆孔和小直(zhi)徑鏜孔；

2.工件(jian)旋(xuan)轉、刀具不旋(xuan)轉只作(zuo)往復運動(dong)，適用(yong)于鏜(tang)大直徑孔和套(tao)料加工；

3.工件不旋(xuan)轉、刀具旋(xuan)轉和(he)往復進給運動，適(shi)用于復雜工件的鉆(zhan)孔(kong)和(he)小(xiao)直(zhi)徑的鉆(zhan)孔(kong)和(he)小(xiao)直(zhi)徑鏜孔(kong)。

本身(shen)剛性強，精(jing)度保持好，主軸(zhou)轉(zhuan)速范圍(wei)廣，進(jin)給系(xi)統(tong)由交(jiao)流(liu)伺服(fu)電機(ji)驅動，能適(shi)應各種深孔加(jia)工(gong)(gong)工(gong)(gong)藝的需(xu)要。

深孔鉆：

對長(chang)徑比大于10的(de)深(shen)(shen)孔(kong)(kong)孔(kong)(kong)系和精(jing)密淺孔(kong)(kong)進行鉆削(xue)加工的(de)的(de)機床(chuang)統稱為深(shen)(shen)孔(kong)(kong)鉆床(chuang)。

加工(gong)出來的(de)(de)孔(kong)位置(zhi)準(zhun)確，尺寸精度(du)好(hao)；直(zhi)線度(du)、同軸度(du)高，并且有很(hen)高的(de)(de)表(biao)面光潔度(du)和(he)重復性(xing)。能(neng)夠(gou)方便的(de)(de)加工(gong)各(ge)種(zhong)形式的(de)(de)深孔(kong)，對于各(ge)種(zhong)特殊形式的(de)(de)深孔(kong)，比如交(jiao)叉孔(kong)、斜孔(kong)、盲孔(kong)及平底盲孔(kong)等也(ye)能(neng)很(hen)好(hao)的(de)(de)解(jie)決。其(qi)不但可用來加工(gong)大長(chang)徑(jing)比的(de)(de)深孔(kong)（大可達300倍），也(ye)可用來加工(gong)精密淺孔(kong)，其(qi)小(xiao)的(de)(de)鉆削孔(kong)徑(jing)可達0.7mm。

◇深孔加工是處于封閉或半(ban)封閉的狀態下，故不能直(zhi)接觀察(cha)到刀具的切(qie)削(xue)情(qing)況(kuang)。目前只(zhi)能憑經驗，通過(guo)聽聲音、看切(qie)削(xue)、觀察(cha)機床負荷(he)及(ji)壓力(li)表、觸(chu)摸震動等外(wai)觀現象來判斷(duan)切(qie)削(xue)過(guo)程是否正常。

◇切(qie)(qie)(qie)削熱不易(yi)傳散。一般切(qie)(qie)(qie)削過(guo)程中有80%的(de)切(qie)(qie)(qie)削熱被切(qie)(qie)(qie)屑帶走，而深孔鉆(zhan)削只有40%，刀(dao)(dao)具占(zhan)切(qie)(qie)(qie)削熱的(de)比例較大，擴散遲、易(yi)過(guo)熱，三坐標深孔槍鉆(zhan)機床批發(fa)，刀(dao)(dao)口溫度(du)可達600度(du)，必須采取強制有效的(de)冷(leng)卻方式。 ◇切(qie)(qie)(qie)屑不易(yi)排出。由于孔深，切(qie)(qie)(qie)屑經過(guo)的(de)路線(xian)長，容(rong)易(yi)發(fa)生堵塞，造成鉆(zhan)頭崩刀(dao)(dao)。因此，切(qie)(qie)(qie)屑的(de)長短和(he)形狀(zhuang)要加以控(kong)制，并要進行強制性排屑。

◇工藝系統剛(gang)性(xing)差。因受孔(kong)徑(jing)尺寸(cun)限制(zhi)，孔(kong)的長徑(jing)比較大，鉆(zhan)桿細而(er)長，剛(gang)性(xing)差，易(yi)產生震動，鉆(zhan)孔(kong)易(yi)走偏(pian)，因而(er)支撐導向極(ji)為重要。這(zhe)點(dian)在(zai)鉆(zhan)機床中更為突出。
