style="text-indent:25px">內(nèi)孔車刀缺點(diǎn)：由于內(nèi)孔車刀是利用刀桿的夾持部分來(lái)安裝在車床刀架上的，所以刀桿部分和切削部分都是懸空的，長(zhǎng)度有60mm左右，經(jīng)過(guò)刃磨后，刀桿直徑只有9mm，且加工的有效長(zhǎng)度有33mm，當(dāng)精加工轉(zhuǎn)速相對(duì)較高，精加工的余量留不多情況下，會(huì)出現(xiàn)刀桿剛性差，振動(dòng)大，加工出來(lái)的內(nèi)孔表面容易產(chǎn)生波紋，影響內(nèi)孔精度。當(dāng)?shù)退倬噧?nèi)孔時(shí)，車出來(lái)的孔雖然表面粗糙度較小，但容易產(chǎn)生錐度，使內(nèi)孔的尺寸精度受到影響。要消除內(nèi)孔錐度，雖可將低速改為中速切削，但又由于切削時(shí)刀具會(huì)產(chǎn)生積屑瘤，使車出來(lái)的內(nèi)孔表面粗糙度增大。</p><p style="text-indent:25px">車刀是金屬切削加工中應(yīng)用可以廣的一種刀具。它可以在車床上加工外圓、端平面、螺紋、內(nèi)孔，也可用于切槽和切斷等。車刀在結(jié)構(gòu)上可分為整體車刀、焊接裝配式車刀和機(jī)械夾固刀片的車刀。機(jī)械夾固刀片的車刀又可分為機(jī)床車刀和可轉(zhuǎn)位車刀。機(jī)械夾固車刀的切削性能穩(wěn)定，工人不必磨刀，所以在現(xiàn)替代產(chǎn)中應(yīng)用越來(lái)越多?？准庸さ毒咭话憧煞譃閮纱箢悾阂活愂菑膶?shí)體材料上加工出孔的刀具，常用的有麻花鉆、中心鉆和深孔鉆等；另一類是對(duì)工件上已有孔進(jìn)行再加工的刀具，常用的有擴(kuò)孔鉆、鉸刀及鏜刀等。例如，下圖示標(biāo)準(zhǔn)高速鋼麻花鉆的結(jié)構(gòu)。工作部分（刀體）的前端為切削部分，承擔(dān)主要的切削工作，后端為導(dǎo)向部分，起引導(dǎo)鉆頭的作用，也是切削部分的后備部分。內(nèi)孔車刀可做成整體式；為節(jié)省刀具材料和增加刀柄強(qiáng)度，也可把高速鋼或硬質(zhì)合金做成較小的刀頭，安裝在碳鋼或合金鋼制成的刀柄前端的方孔中，上面用螺釘固定。機(jī)械夾固式車刀可以避免硬質(zhì)合金刀片在高溫焊接時(shí)產(chǎn)生應(yīng)力和裂紋，并且刀柄可多次使用。</p><div

style="text-indent:25px">刀具正前角和負(fù)前角各有什么優(yōu)缺點(diǎn)？刀具正前角：優(yōu)點(diǎn)：減小切削力，刀具更鋒利。缺點(diǎn)：刀具本身的強(qiáng)度也下降，刀具容易蹦刃。刀具負(fù)前角：優(yōu)點(diǎn)：使刀具受的是壓應(yīng)力，刀具就不容易蹦刃了。缺點(diǎn)：增大了切削力，刀具沒(méi)有同樣的正前角刀鋒利。前角大的話，刀片的切削刃會(huì)比較鋒利，那么切削會(huì)輕快，變形比較小，摩擦也比較小。前角小的話，刀片的切削刃會(huì)比較鈍一點(diǎn)，摩擦系數(shù)會(huì)增大，但是刀片的抗沖擊性能會(huì)增加，適合粗加工。大前角主要加工材料為塑性材料，軟材料以及精加工。小前角主要加工材料為脆性材料，硬材料。車刀在結(jié)構(gòu)上可分為整體車刀、焊接裝配式車刀和機(jī)械夾固刀片的車刀。天津金剛石車刀批發(fā)</p><p

style="text-indent:25px">焊接內(nèi)孔車刀刀具的選擇，主要的問(wèn)題是刀桿的剛性，刀桿的強(qiáng)度，應(yīng)力，扭轉(zhuǎn)應(yīng)力，剪切應(yīng)力等都考慮。在切削過(guò)程中產(chǎn)生的切削力大小相等，方向相反地作用在刀具、工件、夾具和機(jī)床上。（1）主切削力Fz垂直于基面，與切削速度方向一致，所以又稱切向力。在切削加工中，主切削力所消耗的功可以多，所以它是計(jì)算機(jī)床功率、刀桿和刀片強(qiáng)度以及夾具設(shè)計(jì)、選擇切削用量等的主要依據(jù)。（2）徑向力Fy在基面內(nèi)，并與進(jìn)給方向相垂直，也叫背向力。在車削外圓時(shí)，徑向力使工件在水平面內(nèi)彎曲。它會(huì)影響工件的形狀精度，而且容易引起振動(dòng)。（3）軸向力Fx在基面內(nèi)，它與進(jìn)給方向相平行，也叫進(jìn)給力。軸向力是校核機(jī)床進(jìn)給機(jī)構(gòu)強(qiáng)度的主要依據(jù)。若刀具未加緊，會(huì)因軸向力大而引起偏轉(zhuǎn)；若工件未加緊，會(huì)因軸向力大而將工件向卡盤方向推入。蘇州木工車刀銷售</p></p><br
