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，切削振動就可能是其原因。與斷續(xù)切削一樣，切削振動會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。</p><p
