style="text-indent:25px">粗鏜刀以高的金屬去除率為目的，主要功能是提高工作效率，因此粗鏜刀要有高的強(qiáng)度。對于精度要求不高的孔，粗鏜可以作為較終的工序。對于精度要求高的孔，粗鏜可以切去毛坯孔的大部分余量，提高孔的尺寸精度、降低表面粗糙度值，為半精鏜和精鏜做好準(zhǔn)備。粗鏜刀的選擇：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。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)對大切削量和保證孔徑尺寸穩(wěn)定，因此不是隨便一把刀就能保證的。</p><p style="text-indent:25px">雙刃鏜刀是定尺寸的鏜孔刀具，通過改變兩刀刃之間的距離，實(shí)現(xiàn)對不同直徑孔的加工；兩個(gè)刀刃在兩個(gè)對稱位置同時(shí)切削，可消除由徑向切削力對鏜桿的作用而造成的加工誤差。有固定式鏜刀、可調(diào)式和浮動(dòng)式三種。鏜刀的使用方法是什么呢？刀具安裝時(shí)，要特別注意清潔。鏜孔刀具無論是粗加工還是精加工，在安裝和裝配的各個(gè)環(huán)節(jié)，都必須注意清潔度。刀柄與機(jī)床的裝配，刀片的更換等等，都要擦拭干凈，然后再安裝或裝配，切不可馬虎從事。刀具進(jìn)行預(yù)調(diào)，其尺寸精度，完好狀態(tài)、必須符合要求。可轉(zhuǎn)位鏜刀、除單刃鏜刀外，一般不采用人工試切的方法，所以加工前的預(yù)調(diào)就顯得非常重要。預(yù)調(diào)的尺寸必須精確，要調(diào)在公差的中下限，并考慮因溫度的因素，進(jìn)行修正、補(bǔ)償。刀具預(yù)調(diào)可在**預(yù)調(diào)儀、機(jī)上對刀器或其他量儀上進(jìn)行。當(dāng)機(jī)床功率低而需要降低切削力、存在振動(dòng)問題時(shí)，單刃鏜刀是合適的選擇。</p><div

style="text-indent:25px">硬質(zhì)合金鏜刀：切削冷卻。通常采用冷卻液來降低切削熱。這對車削外圓來說簡單易行，但對鏜內(nèi)孔來說卻很困難，因?yàn)殓M孔時(shí)孔內(nèi)有鏜桿和需要冷卻的切屑。冷卻液噴口置于靠近孔口位置會(huì)妨礙切削。因此，方式是通過鏜桿提供內(nèi)部冷卻液，沿鏜桿圓周方向提供充足流量的冷卻液是一種理想方案，可使冷卻液阻力小且可到達(dá)所鏜孔的底部，這通常需要在多處放置冷卻液噴口，如在主后刀面、前刀面和副后刀面處。為了響應(yīng)充足冷卻液的需求，提供帶冷卻環(huán)技術(shù)的刀桿，可使冷卻液施加于鏜桿圓周方向，讓冷卻液包裹鏜桿。加工幾個(gè)零件之后如果有崩刃產(chǎn)生，可能的原因是遇到了斷續(xù)切削，如遇到交叉孔或鍵槽。對于這種情況，需要選用刃口強(qiáng)化的刀具。如果崩刃不是由斷續(xù)切削造成，切削振動(dòng)就可能是其原因。與斷續(xù)切削一樣，切削振動(dòng)會(huì)使刀具受力向下彎曲，然后隨受力的消失而回彈，從而對刀具刃口造成沖擊。一種可能的解決方法是增大進(jìn)給速度，進(jìn)給速度增大10%，可充分增大切削壓力使刀具保持受壓狀態(tài)，以避免回彈對刃口造成沖擊。關(guān)鍵是如果正確選擇鏜刀刀柄，對于這點(diǎn)，大家可以從以下點(diǎn)入手。機(jī)用鏜刀定制</p><p
