style="text-indent:25px">車刀的切削部分由主切削刃、副切削刃、前刀面、后刀面和副后刀面等組成。它的幾何形狀由前角γo、后角αo、主偏角κr、刃傾角γS、副偏角κr’和刀尖圓弧半徑rε所決定。車刀幾何參數(shù)的選擇受多種因素影響，必須根據(jù)具體情況選取。前角γo根據(jù)工件材料的成分和強(qiáng)度來(lái)選取，切削強(qiáng)度較高的材料時(shí)，應(yīng)取較小的值。例如，硬質(zhì)合金車刀在切削普通碳素鋼時(shí)前角取10°～15°；在切削鉻錳鋼或淬火鋼時(shí)取 -2°～-10°。一般情況下后角取 6°～10°。主偏角κr根據(jù)工藝系統(tǒng)的剛性條件而定,一般取30°～75°,剛性差時(shí)取較大的值，在車階梯軸時(shí)，由于切削方式的需要取大于或等于90°。刀尖圓弧半徑rε和副偏角κr'一般按加工表面粗糙度的要求而選取。刃傾角γS則根據(jù)所要求的排屑方向和刀刃強(qiáng)度確定。車刀前面的型式主要根據(jù)工件材料和刀具材料的性質(zhì)而定?？梢院?jiǎn)單的是平面型，正前角的平面型適用于高速鋼車刀和精加工用的硬質(zhì)合金車刀。機(jī)夾車刀是采用普通刀片，用機(jī)械夾固的方法將刀片夾持在刀桿上使用的車刀。南京外圓車刀</p><p

style="text-indent:25px">按刀的結(jié)構(gòu)：整體刀（一般是高速鋼或工具鋼材質(zhì)），焊接刀（一般是硬質(zhì)合金刀頭或金剛石，焊接在45#鋼刀體或刀桿上），和機(jī)夾刀（一般是硬質(zhì)合金或超硬陶瓷刀頭，用機(jī)械力夾緊在45#或其他材料刀體上）等。按刀的材質(zhì)：高速鋼、工具鋼、硬質(zhì)合金、超硬陶瓷（如立方氮化硼等）、金剛石等。按刀的用途：外圓刀、內(nèi)孔刀、切槽刀、切斷刀、螺紋刀和各種成型刀。除你說(shuō)的以外，我還要說(shuō)幾個(gè)，因?yàn)楸救俗鰴C(jī)械加工做了十年的。按用途還有割刀、鏜孔刀、R刀、內(nèi)槽刀等，我只能想到這么多了。我公司也有數(shù)控機(jī)床，不過(guò)以前上面的刀全是自己磨的。瑞士焊接車刀報(bào)價(jià)</p><p
