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(méi)有反向間隙，精鏜頭如果有反向間隙的話(huà)，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，蘇州大直徑鏜刀加工廠(chǎng)家，如果能使用到一把沒(méi)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”，蘇州大直徑鏜刀加工廠(chǎng)家。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(jiàn)的是振刀）。對(duì)于這類(lèi)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，蘇州大直徑鏜刀加工廠(chǎng)家，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。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。蘇州大直徑鏜刀加工廠(chǎng)家</p><div
