style="text-indent:25px">鏜刀是一種很常見的擴孔用刀具，在許多機床上都可以用鏜刀鏜孔(如車床、銑床、鏜床及組合機床等)。鏜孔的加工精度可達IT6～IT8，加工表面粗糙度Ra可達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，只有一個主切削刃，其結(jié)構(gòu)簡單、制造方便、通用性強，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，以減少切削時的徑向力。單刃鏜削可用于精加工工序和對切削控制要求苛刻材料的粗加工和精加工。它還可用作當機床功率受到限制時的解決方案。</p><p style="text-indent:25px">雙刃粗鏜刀有2個遍布在管理局兩邊一起鉆削的刀齒，因為鉆削時造成的軸向力相互之間均衡,可增加切削用量,出產(chǎn)高效率。雙刃粗鏜刀具備無極調(diào)節(jié)，聯(lián)接平穩(wěn)，刀座可拆換，實用性好等特性。一、雙刃粗鏜數(shù)控刀片調(diào)節(jié)較先要松掉卡緊螺絲，依據(jù)標尺線對刀座開展粗調(diào)對應(yīng)點。二、扭緊卡緊螺絲，對刀座開展確定，再擰上3。調(diào)節(jié)螺絲，頂緊在卡緊螺絲桿部，防止讓刀。三、測定擠壓成型孔的規(guī)格與規(guī)定規(guī)格較為，測算出偏小標值。四、略微松掉卡緊螺絲，使調(diào)節(jié)螺絲能夠促進刀座聯(lián)通。五、頂調(diào)節(jié)螺絲用百分表比照，使聯(lián)通量至測算出的偏小標值。六、卡緊卡緊螺絲，擠壓成型鋼件至規(guī)格規(guī)定。如果通過檢查發(fā)現(xiàn)鏜桿頭仍在孔內(nèi)且很難取出，可能的原因是孔內(nèi)切屑堆積導(dǎo)致此災(zāi)難性故障。</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床上卸下來，再安裝到一臺對刀儀上對鏜刀尺寸進行微調(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，是因為直接在機床上對普通鏜頭的游標刻度盤進行讀數(shù)和預(yù)調(diào)相當困難，但是，這種操作方式可能造成鏜孔尺寸超差或損壞工件。由于在機床上安裝鏜刀時難以預(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，則可能實現(xiàn)直接在機床主軸上對刀具鏜孔直徑進行微調(diào)。即使因為機床主軸的進刀限制，必須將鏜刀從機床上卸下來進行孔徑尺寸調(diào)整，新型數(shù)顯鏜刀的調(diào)刀過程也更快速、更精確?？稍阽M刀加工一兩個孔后檢查是否有積屑瘤或崩刃存在。上海大孔鏜刀訂制</p><p
