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。較簡(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。</p><p style="text-indent:25px">安裝車孔時(shí)還應(yīng)注意以下問(wèn)題：（1）機(jī)床運(yùn)動(dòng)精度及工藝系統(tǒng)剛性應(yīng)盡量高。（2）切削用量要選擇合理，一是通過(guò)切削用量控制切屑形狀，方便排屑，二是注意刀具壽命滿足孔加工長(zhǎng)度要求。（3）孔加工關(guān)鍵問(wèn)題除排屑外，還需很好解決高的切削溫度。充分有效的冷卻是不可缺少的手段，選擇水基切削液冷卻。（4）刃磨內(nèi)孔車刀時(shí)要求切削刃有大的前角，保持切削刃強(qiáng)度的前提下切削刃盡量鋒利。（5）卷屑槽型和刀具刃磨角度要合理，孔的粗加工要求切屑為小的“C”型屑，本次設(shè)計(jì)焊接內(nèi)孔車刀在車孔時(shí)應(yīng)注意保持足夠的切削液以輔助排屑和提高刀具壽命。一般要求較小的切削深度，并形成穩(wěn)定連續(xù)的“C”型屑，這樣可提高精車孔過(guò)程的可靠性，保持穩(wěn)定的切削過(guò)程。刃磨刀具不能用力過(guò)大，否則會(huì)使手打滑而觸及砂輪面，造成工傷事故。</p><div

style="text-indent:25px">車刀的刃磨小知識(shí)：砂輪的選用。（1）氧化鋁砂輪：呈白色，其砂粒韌性好，比較鋒利，但硬度稍低，適用于刃磨高速鋼與硬質(zhì)合金的刀桿部分。氧化鋁砂輪也叫剛玉。（2）碳化硅砂輪：呈綠色，其砂粒硬度高，切削性能好，但較脆，適用于刃磨硬質(zhì)合金車刀。砂輪的粗細(xì)以粒度表示，粗磨時(shí)用粗粒度，精磨時(shí)用細(xì)粒度。刃磨斷屑槽的注意事項(xiàng)：砂輪交角處應(yīng)經(jīng)常保持尖銳或具有一定形狀的圓弧，當(dāng)砂輪的棱邊有較大的棱角時(shí)，應(yīng)及時(shí)修整。刃磨的起點(diǎn)位置應(yīng)該與刀尖、主切削刃離開(kāi)一定的距離，與主切削刃的距離為斷屑槽寬度的一半加上倒棱的寬度。刃磨時(shí)，注意不能用力過(guò)大，車刀沿刀柄方向緩慢移動(dòng)。尺寸小的一次成形，尺寸大的可分為粗磨與精磨兩個(gè)過(guò)程磨削成形。瑞士數(shù)控內(nèi)孔車刀銷售</p></p><br
