style="text-indent:25px">焊接內(nèi)孔車刀刀具的選擇，主要的問題是刀桿的剛性，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。</p><p style="text-indent:25px">車刀材料應(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.足夠的硬度一般來說，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，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^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。刀刃用鈍后可以轉(zhuǎn)位繼續(xù)使用，而且停車換刀時(shí)間短，因此取得了迅速發(fā)展。</p><div

style="text-indent:25px">刀具切削性能的好壞，主要取決于刀具材料的切削性能的優(yōu)劣和刀具切削部分的結(jié)構(gòu)與幾何參數(shù)的選擇是否合理。通常所說的刀具材料是指刀具切削部分直接承擔(dān)金屬切除任務(wù)的材料，它的性能直接影響刀具的耐用度和生產(chǎn)率的高低、刀具消耗和成本的多少、加工精度和表面質(zhì)量的優(yōu)劣等，是保證刀具高效工作的基本條件。在金屬切削加工中，刀具材料的切削性能直接影響著生產(chǎn)效率、工件的加工精度、已加工表面質(zhì)量和刀具消耗以及加工成本。正確選擇刀具材料是設(shè)計(jì)和選用刀具的重要內(nèi)容之一，特別是對(duì)某些難加工材料的切削，刀具材料的選用顯得尤為重要。刀具材料的發(fā)展在一定程度上推動(dòng)著金屬切削加工技術(shù)的進(jìn)步。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。徐州外圓精車刀批發(fā)</p><p
