加工前應(yīng)先觀察刀片的使用程度，若刀片需要更換則應(yīng)注意舊刀片更換前刀尖部分已經(jīng)磨損，更換新刀片后鏜孔比之前要大，加工人員應(yīng)根據(jù)刀片磨損程度進(jìn)行調(diào)刀。2) 微調(diào)鏜刀在使用前應(yīng)先觀察鏜刀頭后的擰緊螺釘是否緊固，若無(wú)緊固或緊固不牢靠則會(huì)導(dǎo)致加工中出現(xiàn)孔前后大小不一致，表面粗糙度不好等現(xiàn)象。調(diào)試精鏜刀時(shí)應(yīng)先把鏜刀頭后的緊固螺釘擰松，為了更好的調(diào)整精度，不要讓緊固螺釘很松，一般情況下擰松1-2圈即可。然后按照刀體上的刻度按順時(shí)針撥動(dòng)鏜刀頭的刻度盤(pán)，這里要注意每擰一個(gè)刻度標(biāo)示鏜刀直徑會(huì)增大0.01mm。在調(diào)整尺寸時(shí)應(yīng)注意為防止精鏜刀頭與刻度盤(pán)之間存在反向間隙，應(yīng)先向相反方向擰一圈后在回正，然后根據(jù)試刀直徑調(diào)到需要的尺寸，要注意的是孔本身有公差，在調(diào)刀時(shí)應(yīng)把范圍控制在孔公差的中間部分或公差下限，這樣可以避免精鏜刀出現(xiàn) 不穩(wěn)定時(shí)保證孔的加工尺寸。</p><p style="text-indent:25px">通過(guò)實(shí)際加工可知，采用硬質(zhì)合金刀片的鏜刀在大多數(shù)的應(yīng)用場(chǎng)工作良好且經(jīng)濟(jì)合算。與鉆頭或絞刀不同，單刃鏜刀與工件只有一個(gè)接觸點(diǎn)，因此鏜桿沒(méi)有得到有效支撐。這在某些情況下會(huì)造成振動(dòng)或顫振。顫振問(wèn)題是這類刀具的重大缺陷。要消除車床上鏜孔產(chǎn)生的顫振，較簡(jiǎn)單的方法是采用直徑更大的鏜桿。但是，采用直徑更大的鏜桿并不總是可取的方法。這時(shí)有必要選擇其他方法。有時(shí)，通過(guò)簡(jiǎn)單地調(diào)整切削速度和進(jìn)給速度來(lái)改變切削力，就可解決問(wèn)題。增大進(jìn)給速度或/和降低切削速度可以增大切削力。增大徑向切深也可增大切削力。有時(shí)需要調(diào)整所有的切削用量來(lái)消除振動(dòng)。鏜刀有兩個(gè)分布在中心兩側(cè)同時(shí)切削的刀齒，由于切削時(shí)產(chǎn)生的徑向力互相平衡,可加大切削用量,生產(chǎn)效率高。</p><div

style="text-indent:25px">大多數(shù)鏜刀都需要通過(guò)試切－測(cè)量操作來(lái)確定其設(shè)定尺寸，即首先對(duì)一小部分被加工孔進(jìn)行試切鏜削，然后測(cè)量其加工孔徑。通常，這就意味著需要將鏜刀從機(jī)床上卸下來(lái)，再安裝到一臺(tái)對(duì)刀儀上對(duì)鏜刀尺寸進(jìn)行微調(diào)修正，以獲得正確的孔徑尺寸。這種預(yù)調(diào)操作之所以必要，是因?yàn)橹苯釉跈C(jī)床上對(duì)普通鏜頭的游標(biāo)刻度盤(pán)進(jìn)行讀數(shù)和預(yù)調(diào)相當(dāng)困難，但是，這種操作方式可能造成鏜孔尺寸超差或損壞工件。由于在機(jī)床上安裝鏜刀時(shí)難以預(yù)測(cè)其刀尖偏差，因此需要采用試切－測(cè)量操作來(lái)預(yù)調(diào)刀具。如果采用易于讀數(shù)的新型數(shù)顯鏜刀，則可能實(shí)現(xiàn)直接在機(jī)床主軸上對(duì)刀具鏜孔直徑進(jìn)行微調(diào)。即使因?yàn)闄C(jī)床主軸的進(jìn)刀限制，必須將鏜刀從機(jī)床上卸下來(lái)進(jìn)行孔徑尺寸調(diào)整，新型數(shù)顯鏜刀的調(diào)刀過(guò)程也更快速、更精確。聯(lián)軸機(jī)構(gòu)提高鏜刀的穩(wěn)定性。通孔鏜刀定制</p><p style="text-indent:25px">鏜刀可以校正原有孔軸線的偏斜或位置誤差，是結(jié)構(gòu)較簡(jiǎn)單的刀具之一。通孔鏜刀定制</p><p style="text-indent:25px">數(shù)控加工中鏜孔加工尤其是精鏜孔環(huán)節(jié)是切削加工中的難題之一，往往需要富有經(jīng)驗(yàn)的大師傅才能加工出理想的效果。但是現(xiàn)在隨著高精度鏜刀的應(yīng)用，鏜孔加工變得越來(lái)越簡(jiǎn)便。即便如此，鏜孔加工也依然是孔加工中的難點(diǎn)，更關(guān)鍵是如果正確選擇鏜刀，大多數(shù)人都不太重視粗鏜刀，往往容易忽略粗鏜加工的重要性。其實(shí)粗鏜加工是非常重要，它直接影響到后一道精鏜孔加工的效果，具體體現(xiàn)在粗鏜后留給精加工切削的余量是否穩(wěn)定（即余量是否均勻）。粗鏜刀的選擇要注重鏜刀的剛性和易操作性，一把好的粗鏜刀需要能應(yīng)對(duì)大切削量和保證孔徑尺寸穩(wěn)定，因此不是隨便一把鏜刀就能保證的。通孔鏜刀定制</p><p
