style="text-indent:25px">內孔車刀缺點：由于內孔車刀是利用刀桿的夾持部分來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，長度有60mm左右，經過刃磨后，刀桿直徑只有9mm，且加工的有效長度有33mm，當精加工轉速相對較高，精加工的余量留不多情況下，會出現(xiàn)刀桿剛性差，振動大，加工出來的內孔表面容易產生波紋，影響內孔精度。當?shù)退倬噧瓤讜r，車出來的孔雖然表面粗糙度較小，但容易產生錐度，使內孔的尺寸精度受到影響。要消除內孔錐度，雖可將低速改為中速切削，但又由于切削時刀具會產生積屑瘤，使車出來的內孔表面粗糙度增大。瑞士手動車刀刀刃用鈍后可以轉位繼續(xù)使用，而且停車換刀時間短，因此取得了迅速發(fā)展。</p><div

style="text-indent:25px">陶瓷刀片與立方氮化硼刀片應用區(qū)別??立方氮化硼在材料學中雖歸于陶瓷大類，但由于CBN，SIN，Al2O3，SiN材料的性能差異，陶瓷刀片不及立方氮化硼刀片的韌性和硬度。所以根據(jù)其硬度和韌性的差異，在切削硬度低于50HRC以下和小切深小進給情況下的淬火鋼工件時，陶瓷刀片是較好的選擇。立方氮化硼刀片適合于工件硬度高于50HRC情況。除此之外，在相同后刀面磨損情況下，立方氮化硼刀片切削后的工件表面殘余應力也比陶瓷刀片相對穩(wěn)定。所以在陶瓷刀片的適合加工領域中，也可選用立方氮化硼刀片，用戶可根據(jù)成本效益和加工需求，來確定哪一種刀片材料更經濟。</p><p style="text-indent:25px">陶瓷車刀：?陶瓷車刀是由氧化鋁粉未，添加少量元素，再經由高溫燒結而成，其硬度、抗熱性、切削速度比碳化鎢高，但是因為質脆，故不適用于非連續(xù)或重車削，只適合高速精削。?陶瓷車刀的種類及發(fā)展脈絡??陶瓷刀片的種類及發(fā)展：陶瓷刀片可以明顯的發(fā)展線條是刀片的韌性依次增強：氧化鋁陶瓷刀片—-復合氧化鋁陶瓷刀片--氮化硅陶瓷刀片--立方氮化硼刀片。??在金屬切削領域，氧化鋁陶瓷刀片和氮化硅陶瓷刀片合稱為陶瓷刀片；在無機非金屬材料學中，立方氮化硼材料歸于陶瓷材料大類，立方氮化硼材料刀具的問世，是陶瓷刀具的**。近期推出純氮化硼燒結體陶瓷刀片，其韌性和耐磨性能明顯增加。機夾車刀是采用普通刀片，用機械夾固的方法將刀片夾持在刀桿上使用的車刀。</p><div

style="text-indent:25px">因工件之加工方式不同而采用不同的刀刃外形，一般可區(qū)分為：(1)右手車刀：由右向左，車削工件外徑。(2)左手車刀：由左向右，車削工件外徑。(3)圓鼻車刀：刀刃為圓弧形，可以左右方向車削，適合圓角或曲面之車削。(4)右側車刀：車削右側端面。(5)左側車刀：車削左側端面。(6)切斷刀：用於切斷或切槽。(7)內孔車刀：用於車削內孔。(8)外螺紋車刀：用於車削外螺紋。(9)內螺紋車刀：用於車削內螺紋。車刀屬於單鋒刀具，因車削工作物形狀不同而有很多型式，但它各部位的名稱及作用卻是相同的。一支良好的車刀必須具有剛性良好的刀柄及鋒利的刀鋒兩大部份。車刀的刀刃角度，直接影響車削效果，不同的車刀材質及工件材料、刀刃的角度亦不相同。車床用車刀具有四個重要角度，即前間隙角、邊間隙角、後斜角及邊斜角。對于要求斷屑的車刀，可用帶負倒棱的圓弧面型，或在平面型的前面上磨出斷屑臺。杭州切斷車刀價格</p><p

style="text-indent:25px">車刀材料應具備的性能：3.足夠的強度和韌性（堅韌性）強度是指抵抗切削力的作用而不至于崩刃或刀桿折斷所應具備的性能，一般用抗彎強度來表示。沖擊韌性是指刀具材料在斷續(xù)切削或有沖擊的工作條件下保證不崩刃的能力。強度越高，承受切削抗力的能力越大，刃口崩損的傾向小。4.良好的導熱性刀具材料的導熱性用熱導率（單位為W/m·K）來表示。熱導率大，表示導熱性好，切削時產生的熱量容易傳導出去，從而降低切削部分的溫度、減輕刀具磨損。5.較好的工藝性和經濟性為便于加工制造，要求刀具材料有良好的工藝性能，即具有良好的可加工性能、可磨削性、高溫塑性、鍛造性、焊接性及熱處理工藝性等。工藝性能差的材料不宜制造刀具。6.良好的抗粘接性和化學穩(wěn)定性抗粘接性防止工件與刀具材料分子間在高溫高壓作用下互相吸附產生粘接?；瘜W穩(wěn)定性指刀具材料在高溫下，不易與周圍介質發(fā)生化學反應。刀具材料的種類繁多，且隨著科學技術的發(fā)展，新的刀具材料也不斷出現(xiàn)，常用刀具材料可分為四大類：工具鋼、硬質合金、陶瓷及超硬材料。瑞士內孔車刀批發(fā)</p></p><br
