style="text-indent:25px">車刀的切削部分由主切削刃、副切削刃、前面、后面和副后面等組成。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。負(fù)前角的平面型適用于加工高強(qiáng)度鋼和粗切鑄鋼件的硬質(zhì)合金車刀。帶倒棱的平面型是在正前角平面上磨有負(fù)倒棱以提高切削刃強(qiáng)度，適用于加工鑄鐵和一般鋼件的硬質(zhì)合金車刀。對于要求斷屑的車刀，可用帶負(fù)倒棱的圓弧面型，或在平面型的前面上磨出斷屑臺。車刀按用途可分為外圓、臺肩、端面、切槽、切斷、螺紋和成形車刀等。還有目的自動線和數(shù)字控制機(jī)床用的車刀。車刀，安裝在車床上的用來削切金屬材料的工具。車刀又分，高速鋼車刀、陶瓷刀具、硬質(zhì)合金車刀、立方氮化硼車刀等。</p><p style="text-indent:25px">車刀的刀刃角度：4 邊斜角：從刀頂面自切削邊向另一邊傾斜，此傾斜面和水平面所成角度為邊斜角。此角度是使切屑脫離工作物的角度，使排屑容易并獲得有效之車削。切削一般金屬，高速鋼車刀此角度大約為10~14度，而碳化物車刀可為正傾角也可為負(fù)傾角。5 刀端角：刀刃前端與刀柄垂直之角度。此角度的作用為保持刀刃前端與工件有一間隙避免刀刃與工件磨擦或擦傷已加工之表面。6 切邊角：刀刃前端與刀柄垂直之角度，其作用為改變切層的厚度。同時(shí)切邊角亦可改變車刀受力方向，減少進(jìn)刀阻力，增加刀具壽命，因此一般粗車時(shí)，宜采用切邊角較大之車刀，以減少進(jìn)刀阻力，增加切削速度。7 刀鼻半徑：刀刃可以高點(diǎn)之刀口圓弧半徑。刀鼻半徑大強(qiáng)度大，用於大的切削深度，但容易產(chǎn)生高頻振動。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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">車刀刃磨的方法：（1）人站立在砂輪機(jī)的側(cè)面，以防砂輪碎裂時(shí)，碎片飛出傷人；（2）兩手握刀的距離放開，兩肘夾緊腰部，以減小磨刀時(shí)的抖動；（3）磨刀時(shí)，車刀要放在砂輪的水平中心，刀尖略向上翹約3°~8°，車刀接觸砂輪后應(yīng)作左右方向水平移動。當(dāng)車刀離開砂輪時(shí)，車刀需向上抬起，以防磨好的刀刃被砂輪碰傷；（4）磨后刀面時(shí)，刀桿尾部向左偏過一個(gè)主偏角的角度；磨副后刀面時(shí)，刀桿尾部向右偏過一個(gè)副偏角的角度；（5）修磨刀尖圓弧時(shí)，通常以左手握車刀前端為支點(diǎn)，用右手轉(zhuǎn)動車刀的尾部。磨刀安全知識:(1）刃磨刀具前，應(yīng)首先檢查砂輪有無裂紋，砂輪軸螺母是否擰緊，并經(jīng)試轉(zhuǎn)后使用，以免砂輪碎裂或飛出傷人。2）刃磨刀具不能用力過大，否則會使手打滑而觸及砂輪面，造成工傷事故。3)磨刀時(shí)應(yīng)戴防護(hù)眼鏡，以免砂礫和鐵屑飛入眼中。4）磨刀時(shí)不要正對砂輪的旋轉(zhuǎn)方向站立，以防意外。5）磨小刀頭時(shí)，必須把小刀頭裝入刀桿上。6）砂輪支架與砂輪的間隙不得大于3mm，入發(fā)現(xiàn)過大，應(yīng)調(diào)整適當(dāng)。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。上海車刀訂制</p><p
