車床裝備計劃有兩種辦法可供挑選(xuan)：

工(gong)件旋轉(zhuan);如工(gong)件是回轉(zhuan)體零(ling)件，要加(jia)工(gong)的孔為(wei)同心(xin)孔，則(ze)工(gong)件旋轉(zhuan)為(wei)改(gai)造的計劃。

將(jiang)工(gong)件(jian)用機床三(san)爪卡盤夾(jia)持，若是工(gong)件(jian)較長則需中間(jian)架(jia)支撐。刀具固定(ding)在四方(fang)刀架(jia)或許中托板上。由機床主軸(zhou)股動(dong)工(gong)件(jian)作旋轉運(yun)動(dong)，進給(gei)運(yun)動(dong)由大(da)托板供給(gei)。

這種辦(ban)法的長處(chu)是：裝備(bei)為簡(jian)捷(jie)，本錢也較低。但(dan)也有它的局(ju)限(xian)性(xing)：機床主(zhu)軸轉(zhuan)速一般(ban)情況下不會超越2000轉(zhuan)/min，關于小(xiao)孔徑鉆(zhan)削，機床主(zhu)軸轉(zhuan)速往(wang)往(wang)達不到(dao)(dao)加工需(xu)求。別的小(xiao)進(jin)給速度一般(ban)比較大(da)，為0.04～0.06mm/r。而小(xiao)孔的深孔加工需(xu)求進(jin)給速度較低。以45#鋼(gang)Φ6mm孔為例，需(xu)求進(jin)給0.015mm/r;主(zhu)軸轉(zhuan)速2450r/min。所(suo)以，在小(xiao)孔徑(≤10mm)深孔加工中(zhong)受到(dao)(dao)限(xian)制(zhi)較大(da)。加工前須用機床尾座加工引導(dao)孔。

刀具(ju)(ju)旋轉(zhuan)：和(he)工件旋轉(zhuan)相比較(jiao)，刀具(ju)(ju)旋轉(zhuan)有(you)更(geng)高(gao)的適應性。無(wu)論是(shi)同心孔(kong)(kong)仍是(shi)偏疼孔(kong)(kong)，臥式(shi)深孔(kong)(kong)槍(qiang)鉆機床，無(wu)論孔(kong)(kong)徑巨細(xi)，都能夠在一(yi)般車床上得到(dao)較(jiao)好的處理(li)。

依(yi)據實際情況(kuang)描繪工裝(zhuang)，將工件固(gu)定在(zai)機(ji)床中托板上。并能(neng)(neng)夠(gou)描繪導(dao)向套裝(zhuang)置在(zai)工件前端面，引導(dao)深(shen)(shen)孔鉆進(jin)入。此種辦法不(bu)需(xu)在(zai)深(shen)(shen)孔加(jia)工前加(jia)工引導(dao)孔。大大提(ti)高了加(jia)工功(gong)率。刀具(ju)的(de)裝(zhuang)置可依(yi)據工件的(de)實際情況(kuang)挑選辦法：機(ji)床轉(zhuan)(zhuan)速和小進(jin)給(gei)量(liang)都(dou)能(neng)(neng)滿意加(jia)工需(xu)求(qiu)時，旋(xuan)轉(zhuan)(zhuan)夾具(ju)錐柄直接裝(zhuang)置在(zai)機(ji)床主軸錐孔內。刀具(ju)裝(zhuang)置在(zai)旋(xuan)轉(zhuan)(zhuan)夾具(ju)上。

機(ji)(ji)床(chuang)主軸經過旋轉(zhuan)夾具股(gu)動(dong)(dong)刀(dao)具作旋轉(zhuan)運動(dong)(dong)。進給運動(dong)(dong)由(you)大(da)托板(ban)供(gong)給。 若是機(ji)(ji)床(chuang)主軸轉(zhuan)速(su)和小走刀(dao)速(su)度都不能(neng)滿意加(jia)工需求，深孔(kong)槍鉆機(ji)(ji)床(chuang)，能(neng)夠思(si)考加(jia)裝主軸增速(su)器來調整。

主(zhu)軸(zhou)增(zeng)(zeng)速(su)(su)(su)器增(zeng)(zeng)速(su)(su)(su)比(bi)為3.81，加工小(xiao)孔(kong)(kong)時，機床(chuang)主(zhu)軸(zhou)經(jing)增(zeng)(zeng)速(su)(su)(su)后，簡直能夠滿意一切(qie)孔(kong)(kong)徑的加工。一起(qi)，機床(chuang)的小(xiao)走刀(dao)速(su)(su)(su)度也降低(di)了3.81倍，加工規模更廣(guang)。主(zhu)軸(zhou)增(zeng)(zeng)速(su)(su)(su)器裝置(zhi)(zhi)十(shi)分簡略，增(zeng)(zeng)速(su)(su)(su)器的錐柄裝置(zhi)(zhi)在機床(chuang)主(zhu)軸(zhou)錐孔(kong)(kong)內，旋(xuan)轉夾具(ju)錐柄裝置(zhi)(zhi)在增(zeng)(zeng)速(su)(su)(su)器輸出軸(zhou)內，刀(dao)具(ju)一樣裝在旋(xuan)轉夾具(ju)內。
