style="text-indent:25px">車刀種類和用途車刀是應(yīng)用可以廣的一種單刃刀具。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。車刀刀片特點(diǎn)與要求：（1）定位精度高刀片轉(zhuǎn)位或更換新刀片后，刀尖位置的變化應(yīng)在工件精度允許的范圍內(nèi)。（2）刀片夾緊可靠應(yīng)保證刀片、刀墊、刀桿接觸面緊密貼合，經(jīng)得起沖擊和振動(dòng)，上海內(nèi)孔車刀訂制，上海內(nèi)孔車刀訂制，但夾緊力也不宜過(guò)大，應(yīng)力分布應(yīng)均勻，上海內(nèi)孔車刀訂制，以免壓碎刀片。（3）排屑流暢刀片前面上無(wú)障礙，保證切屑排出流暢，并容易觀察。（4）使用方便轉(zhuǎn)換刀刃和更換新刀片方便、迅速。對(duì)小尺寸刀具結(jié)構(gòu)要緊湊。在滿足以上要求時(shí)，盡可能使結(jié)構(gòu)簡(jiǎn)單，制造和使用方便。硬質(zhì)合金車刀刀尖圓弧半徑rε和副偏角κr'一般按加工表面粗糙度的要求而選取。上海內(nèi)孔車刀訂制</p><div

style="text-indent:25px">陶瓷刀片與立方氮化硼刀片應(yīng)用區(qū)別??立方氮化硼在材料學(xué)中雖歸于陶瓷大類，但由于CBN，SIN，Al2O3，SiN材料的性能差異，陶瓷刀片不及立方氮化硼刀片的韌性和硬度。所以根據(jù)其硬度和韌性的差異，在切削硬度低于50HRC以下和小切深小進(jìn)給情況下的淬火鋼工件時(shí)，陶瓷刀片是較好的選擇。立方氮化硼刀片適合于工件硬度高于50HRC情況。除此之外，在相同后刀面磨損情況下，立方氮化硼刀片切削后的工件表面殘余應(yīng)力也比陶瓷刀片相對(duì)穩(wěn)定。所以在陶瓷刀片的適合加工領(lǐng)域中，也可選用立方氮化硼刀片，用戶可根據(jù)成本效益和加工需求，來(lái)確定哪一種刀片材料更經(jīng)濟(jì)。徐州普通車刀廠家刀片轉(zhuǎn)位或更換新刀片后，刀尖位置的變化應(yīng)在工件精度允許的范圍內(nèi)。</p><div

(1)粗車刀：主要是用來(lái)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(lái)說(shuō)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(lái)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(lái)使用。 (4)切斷車刀：只用端部切削工作物，此車刀可用來(lái)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(guò)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(lái)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(lái)精車肩部的左側(cè)面。</p><p style="text-indent:25px">一般常用車刀材質(zhì)有下列幾種：1 高碳鋼：高碳鋼車刀是由含碳量0.8%~1.5%之間的一種碳鋼，經(jīng)過(guò)淬火硬化後使用，因切削中的摩擦四很容易回火軟化，被高速鋼等其他刀具所取代。一般*適合於軟金屬材料之切削，常用者有SK1，SK2、、、、SK7等。2 高速鋼：高速鋼為一種鋼基合金俗名白車刀，含碳量0.7~0.85%之碳鋼中加入W、Cr、V及Co等合金元素而成。例如18-4-4高速鋼材料中含有18%鎢、4%鉻以及4%釩的高速鋼。高速鋼車刀切削中產(chǎn)生的摩擦熱可高達(dá)至6000C，適合轉(zhuǎn)速1000rpm以下及螺紋之車削，一般常用高速鋼車刀如SKH2、SKH4A、SKH5、SKH6、SKH9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。</p><div
