style="text-indent:25px">加工中心用的鏜刀，就其切削部分而言，與外圓車刀沒有本質(zhì)的區(qū)別，但在加工中心上進(jìn)行鏜孔通常是采用懸臂式的加工，因此要求鏜刀有足夠的剛性和較好的精度。為適應(yīng)不同的切削條件，鏜刀有多種類型。按鏜刀的切削刃數(shù)量可分為單刃鏜刀和雙刃鏜刀。單刃鏜刀：這類鏜刀的刀柄和切削部分做成一體，切削部分以采用硬質(zhì)合金為主。其結(jié)構(gòu)如圖，它只有一個(gè)切削刃，結(jié)構(gòu)緊湊簡單，體積小，制造容易，應(yīng)用較廣，可以鏜削各類小孔、不通孔和臺階孔。若裝在較全刀架或平旋盤滑座上，可以鏜削直徑較大的孔、端面等。但單刃鏜刀剛性差，切削時(shí)易引起振動，所以鏜刀的主偏角選得較大，以減小徑向力。鏜孔徑的大小要靠調(diào)整刀具的懸伸長度來保證，調(diào)整麻煩，效率低，金華瑞士微型轉(zhuǎn)體鏜刀訂制，只能用于單件小批生產(chǎn)，金華瑞士微型轉(zhuǎn)體鏜刀訂制，金華瑞士微型轉(zhuǎn)體鏜刀訂制。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。金華瑞士微型轉(zhuǎn)體鏜刀訂制</p><div

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。金華瑞士微型轉(zhuǎn)體鏜刀訂制大孔可用防振鏜桿或者特殊的防振鏜頭。</p><div

style="text-indent:25px">大多數(shù)鏜刀都需要通過試切-測量操作來確定其設(shè)定尺寸，即首先對一小部分被加工孔進(jìn)行試切鏜削，然后測量其加工孔徑。通常，這就意味著需要將鏜刀從機(jī)床上卸下來，再安裝到一臺對刀儀上對鏜刀尺寸進(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)測其刀尖偏差，因此需要采用試切-測量操作來預(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。</p><p style="text-indent:25px">鏜刀使用注意事項(xiàng)：故障處理。更換前軸承及潤滑脂，調(diào)整軸承游隙，軸向游隙0.003mm，徑向游隙士0.002mm；自制簡易研具，手工研磨主軸內(nèi)錐孔定位面，用涂色法檢查，保證刀柄與主軸定心錐孔的接觸面積大于85%；更換碟形彈簧。將修好的主軸裝回主軸箱，用千分表檢查徑向跳動，近端小于0.006mm，遠(yuǎn)端150mm處小于0.010mm。試加工，主軸溫升和噪聲正常，加工精度滿足加工工藝要求，故障排除。改進(jìn)措施：①增加壓縮空氣精濾和干燥裝置，過濾器要定期排水，定期清洗或更換濾芯；②隨時(shí)檢查主軸錐孔、刀柄的清潔和配合狀況，檢查空氣干燥器工作是否正常；③合理安排加工工藝，避免材料切除率陡變；④嚴(yán)禁超負(fù)荷運(yùn)行，有故障應(yīng)及時(shí)報(bào)修，不得帶故障運(yùn)行。當(dāng)采用特殊附件時(shí)，也可加工內(nèi)外球面、錐孔等。</p><div

style="text-indent:25px">單刃微調(diào)精鏜刀：本實(shí)用新型涉及一種孔加工用單刃微調(diào)精鏜刀，包括刀體和刀桿，其特征在于：所述刀體內(nèi)置有滑動刀夾，滑動刀夾上固定有微調(diào)螺母，微調(diào)螺桿通過限位螺母、限位襯套和刀體連接，所述微調(diào)螺母與所述微調(diào)螺桿組成一對螺紋傳動機(jī)構(gòu)，所述滑動刀夾端部置有刀桿，并由鎖緊螺釘鎖緊固定，刀片置于所述刀桿的端部。所述微調(diào)螺桿的一端設(shè)置有刻度盤，刻度盤與所述限位螺母之間安裝有蝶形彈簧。與現(xiàn)有的微調(diào)精鏜刀相比，本實(shí)用新型結(jié)構(gòu)緊湊，采用螺紋傳動機(jī)構(gòu)調(diào)整方便，鏜孔范圍可從φ2mm至φ150mm，刻度盤每旋轉(zhuǎn)一格，精度為0.01mm，調(diào)整范圍大，調(diào)整精度高。微調(diào)鏜刀：適用于自動線、坐標(biāo)鏜床和數(shù)控機(jī)床上的微調(diào)鏜刀。上海外圓鏜刀批發(fā)</p><p

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。金華瑞士微型轉(zhuǎn)體鏜刀訂制</p></p><br
