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°，杭州內(nèi)孔車刀廠家,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，杭州內(nèi)孔車刀廠家。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?？梢院唵蔚氖瞧矫嫘?，杭州內(nèi)孔車刀廠家，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。平體成形車刀外形為平條狀,與普通車刀相似,刃形具有一定的廓形。杭州內(nèi)孔車刀廠家</p><div

style="text-indent:25px">車刀種類和用途車刀是應(yīng)用廣的一種單刃刀具。也是學(xué)習(xí)、分析各類刀具的基礎(chǔ)。車刀用于各種車床上，加工外圓、內(nèi)孔、端面、螺紋、車槽等。車刀按結(jié)構(gòu)可分為整體車刀、焊接車刀、機(jī)夾車刀、可轉(zhuǎn)位車刀和成型車刀。其中可轉(zhuǎn)位車刀的應(yīng)用日益普遍，在車刀中所占比例逐漸增加。一、硬質(zhì)合金焊接車刀所謂焊接式車刀，就是在碳鋼刀桿上按刀具幾何角度的要求開出刀槽，用焊料將硬質(zhì)合金刀片焊接在刀槽內(nèi)，并按所選擇的幾何參數(shù)刃磨后使用的車刀。二、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。此類刀具有如下特點(diǎn)：（1）由于刀具耐用度提高，使用時(shí)間較長，換刀時(shí)間縮短，提高了生產(chǎn)效率。（2）壓緊刀片所用的壓板端部，可以起斷屑器作用。杭州自動(dòng)車床車刀銷售廠家一條切削刃用鈍后可迅速轉(zhuǎn)位換成相鄰的新切削刃，即可繼續(xù)工作。</p><div

style="text-indent:25px">車刀尖型 (1)粗車刀：主要是用來切削大量且多余部份使工作物直徑接近需要的尺寸。粗車時(shí)表面光度不重要，因此車刀尖可研磨成尖銳的刀峰，但是刀峰通常要有微小的圓度以避免斷裂。 (2)精車刀：此刀刃可用油石礪光，以便車出非常圓滑的表面光度，一般來說精車刀之圓鼻比粗車刀大。 (3)圓鼻車刀：可適用許多不同型式的工作是屬于常用車刀，磨平頂面時(shí)可左右車削也可用來車削黃銅。此車刀也可在肩角上形成圓弧面，也可當(dāng)精車刀來使用。 (4)切斷車刀：只用端部切削工作物，此車刀可用來切斷材料及車度溝槽。 (5)螺絲車刀(牙刀)：用于車削螺桿或螺帽，依螺紋的形式分60度，或55度V型牙刀，29度梯形牙刀、方形牙刀。 (6)鏜孔車刀：用以車削鉆過或鑄出的孔。達(dá)至光制尺寸或真直孔面為目的。 (7)側(cè)面車刀或側(cè)車刀：用來車削工作物端面，右側(cè)車刀通常用在精車軸的未端，左側(cè)車則用來精車肩部的左側(cè)面。按結(jié)構(gòu)可分為整體車刀、焊接車刀、機(jī)夾車刀、可轉(zhuǎn)位車刀和成型車刀。</p><div
