style="text-indent:25px">鏜刀是一種很常見的擴(kuò)孔用刀具，在許多機(jī)床上都可以用鏜刀鏜孔(如車床、銑床、鏜床及組合機(jī)床等)。鏜孔的加工精度可達(dá)IT6～I(xiàn)T8，加工表面粗糙度Ra可達(dá)6.3μm～0.8μm，常用于較大直徑的孔的粗加工、半精加工和精加工。根據(jù)鏜刀的結(jié)構(gòu)特點(diǎn)及使用方式，可分為單刃鏜刀和多刃鏜刀。單刃鏜刀的刀頭結(jié)構(gòu)與車刀相似，只有一個(gè)主切削刃，其結(jié)構(gòu)簡(jiǎn)單、制造方便、通用性強(qiáng)，但剛度比車刀差得多。因此，單刃鏜刀通常選取較大的主偏角和副偏角、較小的刃傾角和刀尖圓弧半徑，以減少切削時(shí)的徑向力。單刃鏜削可用于精加工工序和對(duì)切削控制要求苛刻材料的粗加工和精加工。它還可用作當(dāng)機(jī)床功率受到限制時(shí)的解決方案。</p><p style="text-indent:25px">鏜刀有多種類型，按其切削刃數(shù)量可分為單刃鏜刀、雙刃鏜刀和多刃鏜刀；按其加工表面可分為通孔鏜刀、盲孔鏜刀、階梯孔鏜刀和端面鏜刀；按其結(jié)構(gòu)可分為整體式、裝配式和可調(diào)式。單刃鏜刀刀頭結(jié)構(gòu)與車刀類似，刀頭裝在刀桿中，根據(jù)被加工孔的大小，通過手工操縱，用螺釘固定刀頭的位置。單刃鏜刀結(jié)構(gòu)簡(jiǎn)單，可以校正原有孔軸線偏斜和小的位置偏差，適應(yīng)性較廣，可用來(lái)進(jìn)行粗加工、半精加工或精加工。但是，所鏜孔徑尺寸的大小要靠人工調(diào)整刀頭的懸伸長(zhǎng)度來(lái)保證，較為麻煩，加之*有一個(gè)主切削刃參加切削，故生產(chǎn)效率較低，多用于單件小批量生產(chǎn)。雙刃鏜刀有兩個(gè)對(duì)稱的切削刃，切削時(shí)徑向力可以相互抵消，工件孔徑尺寸和精度由鏜刀徑向尺寸保證。鏜孔完畢后，擔(dān)心的事情變?yōu)楝F(xiàn)實(shí)：鏜刀頭不見了。</p><div

style="text-indent:25px">精鏜刀的選擇：精鏜屬于孔加工的尾道工序，需要精鏜刀具有精密而穩(wěn)定的徑尺寸微調(diào)功能，精鏜頭的內(nèi)部結(jié)構(gòu)決定了鏜頭刀尖微調(diào)功能的優(yōu)劣。精鏜頭的較高境界是在微調(diào)的時(shí)候沒有反向間隙，精鏜頭如果有反向間隙的話，會(huì)給精鏜加工造成諸多困擾，需要反復(fù)調(diào)整并確認(rèn)。因此，如果能使用到一把沒有反向間隙的精鏜頭，是鏜刀使用人員較高興的事。鏜孔深度：對(duì)于孔加工來(lái)講，深孔和淺孔的意義不是指孔的相對(duì)深度值，而是指的“長(zhǎng)徑比”。對(duì)于鏜刀來(lái)講，這個(gè)“長(zhǎng)徑比”=（鏜桿懸長(zhǎng)）/（鏜桿直徑）。長(zhǎng)徑比比較大的孔在鏜削時(shí)容易發(fā)生加工不良（比較多見的是振刀）。對(duì)于這類加工，一般需要適度改變切削參數(shù)，除此之外可以選擇特殊的鏜桿，小孔可用硬質(zhì)合金材料桿；大孔可用防振鏜桿或者特殊的防振鏜頭?？墒估鋮s液施加于鏜桿圓周方向，讓冷卻液包裹鏜桿。武漢自動(dòng)鏜刀哪家好</p><p style="text-indent:25px">如果檢查發(fā)現(xiàn)斷裂的鏜桿不在孔內(nèi)或在孔內(nèi)很松且取出困難。武漢自動(dòng)鏜刀哪家好</p><p style="text-indent:25px">鏜刀的優(yōu)點(diǎn)：大多數(shù)鏜刀都需要通過試切－測(cè)量(cut-and-measure)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)，其尺寸調(diào)整范圍可達(dá)0.0001〃(0.00254mm)。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)刀過程也更快速、更精確。武漢自動(dòng)鏜刀哪家好</p></p><br
