style="text-indent:25px">單刃鏜刀切削部分的形狀與車(chē)刀相似。為了使孔獲得高的尺寸精度，精加工用鏜刀的尺寸需要準(zhǔn)確地調(diào)整。微調(diào)鏜刀可以在機(jī)床上精確地調(diào)節(jié)鏜孔尺寸，它有一個(gè)精密游標(biāo)刻線的指示盤(pán)，指示盤(pán)同裝有鏜刀頭的心桿組成一對(duì)精密絲桿螺母副機(jī)構(gòu)。當(dāng)轉(zhuǎn)動(dòng)螺母時(shí)，裝有刀頭的心桿即可沿定向鍵作直線移動(dòng)，借助游標(biāo)刻度讀數(shù)精度可達(dá)0.001毫米。鏜刀的尺寸也可在機(jī)床外用對(duì)刀儀預(yù)調(diào)。雙刃鏜刀有兩個(gè)分布在中心兩側(cè)同時(shí)切削的刀齒，由于切削時(shí)產(chǎn)生的徑向力互相平衡,可加大切削用量,生產(chǎn)效率高。雙刃鏜刀按刀片在鏜桿上浮動(dòng)與否分為浮動(dòng)鏜刀和定裝鏜刀。浮動(dòng)鏜刀適用于孔的精加工。它實(shí)際上相當(dāng)于鉸刀，能鏜削出尺寸精度高和表面光潔的孔，但不能修正孔的直線性偏差。為了提高重磨次數(shù)，浮動(dòng)鏜刀常制成可調(diào)結(jié)構(gòu)。無(wú)錫可調(diào)鏜刀哪家好該類(lèi)鏜刀可以校正原有孔軸線的偏斜或位置誤差，是結(jié)構(gòu)較簡(jiǎn)單的刀具之一。</p><div

style="text-indent:25px">雙刃粗鏜刀加工方式又是怎樣的？1、平衡切削。平衡切削，即兩刃軸向高度一致，徑向也保持一致的加工方式，兩刃同時(shí)切削，受相同的切削抵抗力。特點(diǎn)是切削進(jìn)給快，效率高。但需要注意的一點(diǎn)是，如果兩刃的軸向高度有0.1mm的差，每轉(zhuǎn)進(jìn)給0.2mm時(shí)，相當(dāng)于兩刃其中一刃并沒(méi)有切到工件；此時(shí)的兩刃并未達(dá)到平衡切削，很可能出現(xiàn)振刀現(xiàn)象。然而，不同廠家的制造刀片裝夾位置的精度不同以及刀片座裝夾的精度不同，甚至刀片自身的公差，較后裝夾完成時(shí)，軸向高度一致的兩刃實(shí)際還可能存在較大高度差。2、段差切削。段差切削，分為內(nèi)刃和外刃，內(nèi)刃和外刃之間存在高度差，內(nèi)刃與外刃分別加工不同的直徑。與平衡切削相比，其特點(diǎn)是切削量大，且減小鐵屑的寬幅，更容易排屑，但進(jìn)給要慢。其中較值得注意的是兩刃之間的高度差，要求:兩刃高度差≧每轉(zhuǎn)進(jìn)給f×0.5+0.1mm。</p><p style="text-indent:25px">鏜刀刀具設(shè)計(jì)步驟如下：根據(jù)被加工零件材質(zhì)及加工要求，刀片材料選用YG6硬質(zhì)合金基體的新型復(fù)合涂層(TiC+Al2O3+TiN)刀片。根據(jù)被加工零件特點(diǎn)及切削參數(shù)，刀片緊固形式設(shè)計(jì)為螺銷(xiāo)壓孔式結(jié)構(gòu)?？赊D(zhuǎn)位刀片型式選用菱形國(guó)標(biāo)通用刀片，刀尖角為55°，法向后角為7°，單面有V型斷屑槽，刀片厚度S=3.97，刀尖圓角半徑re=0.4±0.1mm；根據(jù)加工精度要求，刀片精度選用M級(jí)。確定可轉(zhuǎn)位刀片型號(hào)為DCMT11T304-V1。刀片切削刃長(zhǎng)度Sa=ap/sinkrcosl=3/sin62.5°cos-4°=3.39mm；粗車(chē)時(shí)應(yīng)滿(mǎn)足切削刃長(zhǎng)度L≥1.5Sa=5.086mm，所選刀片的主切削刃邊長(zhǎng)L≈11.6mm，可滿(mǎn)足切削要求。確定可轉(zhuǎn)位車(chē)刀刀桿與刀夾聯(lián)結(jié)方式：根據(jù)機(jī)床型號(hào)及中心高，為增加刀桿強(qiáng)度，刀桿截面尺寸設(shè)計(jì)為不等截面，裝刀刀夾與刀桿通過(guò)楔面自鎖聯(lián)結(jié)，可使刀具裝卸快捷、準(zhǔn)確、可靠。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)。</p><div
