style="text-indent:25px">焊接式車(chē)刀的特點(diǎn)主要有:1.結(jié)構(gòu)簡(jiǎn)單,制造方便,刀具剛度好。2.使用靈活,可根據(jù)使用要求隨意刃磨。3.刀片利用較充分。4.切削性能較低。刀片經(jīng)過(guò)高溫焊接,切削性能有所下降。又由于硬質(zhì)合金刀片與刀桿材料的線(xiàn)膨脹系數(shù)差別較大,刀片經(jīng)焊和刃磨的高溫作用,因熱應(yīng)力的影響導(dǎo)致刀片產(chǎn)生微裂紋,容易造成崩刃。5.輔助時(shí)間長(zhǎng)。焊接式車(chē)刀換刀和對(duì)刀的時(shí)間較長(zhǎng),不適合自動(dòng)機(jī)床、數(shù)控機(jī)床等自動(dòng)化程度高的機(jī)床使用。6.切削性能主要取決于工人刃磨的技術(shù)水平,與現(xiàn)代化生產(chǎn)不相適應(yīng)。7.刀桿不能重復(fù)使用,刀桿材料消耗較大。目前,焊接式車(chē)刀應(yīng)用仍十分普遍。瑞士自動(dòng)車(chē)床車(chē)刀代理商主要在普通車(chē)床，自動(dòng)車(chē)床商加工回轉(zhuǎn)體內(nèi)外成形表面。</p><div

style="text-indent:25px">測(cè)量車(chē)刀切削角度的輔助平面。為了確定和測(cè)量車(chē)刀的幾何角度，需要選取三個(gè)輔助平面作為基準(zhǔn)，這三個(gè)輔助平面是切削平面、基面和正交平面。1）切削平面——切于主切削刃某一選定點(diǎn)并垂直于刀桿底平面的平面。2）基面——過(guò)主切削刃的某一選定點(diǎn)并平行于刀桿底面的平面。3）正交平面——垂直于切削平面又垂直于基面的平面?？梢?jiàn)這三個(gè)坐標(biāo)平面相互垂直，構(gòu)成一個(gè)空間直角坐標(biāo)系。車(chē)刀的主要幾何角度及選擇：副偏角(Kr’)的選擇原則。首先考慮車(chē)刀、工件和夾具有足夠的剛性，才能減小副偏角；反之，應(yīng)取大值；其次，考慮加工性質(zhì)，精加工時(shí)，副偏角可取10°～15°，粗加工時(shí)，副偏角可取5°左右。５）刃傾角(λS)的選擇原則。主要看加工性質(zhì)，粗加工時(shí)，工件對(duì)車(chē)刀沖擊大，取λS≤0°，精加工時(shí)，工件對(duì)車(chē)刀沖擊力小，取λS≥0°；通常取λS=0°。刃傾角一般在-10°～5°之間選取。</p><p style="text-indent:25px">車(chē)刀材料應(yīng)具備的性能刀具材料是指刀具切削部分的材料。金屬切削時(shí)，刀具切削部分直接和工件及切屑相接觸，承受著很大的切削壓力和沖擊，并受到工件及切屑的劇烈摩擦，產(chǎn)生很高的切削溫度。因此，刀具材料應(yīng)具備一定的性能。1.足夠的硬度一般來(lái)說(shuō)，刀具材料的硬度必須高于被切工件材料的硬度，常溫硬度要求60HRC以上，除此之外，還必須具備較高的高溫硬度（熱硬性）和顯微硬度（金相組織硬度）2.高耐磨性和耐熱性刀具材料的耐磨性是指抵抗磨損的能力。一般說(shuō)，刀具材料硬度越高，耐磨性也越好，但材料的耐磨性不單純?nèi)Q于材料的硬度，也并非材料越硬耐磨性越高。因?yàn)橛捕冗^(guò)高，內(nèi)應(yīng)力增加，可能會(huì)加快表層的破壞，使耐磨性降低。壓緊刀片所用的壓板端部，可以起斷屑器作用。</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(chē)刀：由右向左，車(chē)削工件外徑。(2)左手車(chē)刀：由左向右，車(chē)削工件外徑。(3)圓鼻車(chē)刀：刀刃為圓弧形，可以左右方向車(chē)削，適合圓角或曲面之車(chē)削。(4)右側(cè)車(chē)刀：車(chē)削右側(cè)端面。(5)左側(cè)車(chē)刀：車(chē)削左側(cè)端面。(6)切斷刀：用於切斷或切槽。(7)內(nèi)孔車(chē)刀：用於車(chē)削內(nèi)孔。(8)外螺紋車(chē)刀：用於車(chē)削外螺紋。(9)內(nèi)螺紋車(chē)刀：用於車(chē)削內(nèi)螺紋。車(chē)刀屬於單鋒刀具，因車(chē)削工作物形狀不同而有很多型式，但它各部位的名稱(chēng)及作用卻是相同的。一支良好的車(chē)刀必須具有剛性良好的刀柄及鋒利的刀鋒兩大部份。車(chē)刀的刀刃角度，直接影響車(chē)削效果，不同的車(chē)刀材質(zhì)及工件材料、刀刃的角度亦不相同。車(chē)床用車(chē)刀具有四個(gè)重要角度，即前間隙角、邊間隙角、後斜角及邊斜角。瑞士自動(dòng)車(chē)床車(chē)刀代理商</p></p><br
