2．可轉(zhuǎn)位車刀刀片的夾緊特點(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)，但夾緊力也不宜過大，應(yīng)力分布應(yīng)均勻，以免壓碎刀片。（3）排屑流暢刀片前面上無障礙，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)簡單，制造和使用方便。</p><p style="text-indent:25px">刀具切削性能的好壞，主要取決于刀具材料的切削性能的優(yōu)劣和刀具切削部分的結(jié)構(gòu)與幾何參數(shù)的選擇是否合理。通常所說的刀具材料是指刀具切削部分直接承擔(dān)金屬切除任務(wù)的材料，它的性能直接影響刀具的耐用度和生產(chǎn)率的高低、刀具消耗和成本的多少、加工精度和表面質(zhì)量的優(yōu)劣等，是保證刀具高效工作的基本條件。在金屬切削加工中，刀具材料的切削性能直接影響著生產(chǎn)效率、工件的加工精度、已加工表面質(zhì)量和刀具消耗以及加工成本。正確選擇刀具材料是設(shè)計(jì)和選用刀具的重要內(nèi)容之一，特別是對(duì)某些難加工材料的切削，刀具材料的選用顯得尤為重要。刀具材料的發(fā)展在一定程度上推動(dòng)著金屬切削加工技術(shù)的進(jìn)步。車刀用于各種車床上，加工外圓、內(nèi)孔、端面、螺紋、車槽等。</p><div

style="text-indent:25px">一般使用的車刀尖型式有下列幾種：(1)粗車刀：主要是用來切削大量且多馀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於常用車刀，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)螺紋車刀(牙刀)：用於車削螺桿或螺帽，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)搪孔車刀：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。磨小刀頭時(shí)，必須把小刀頭裝入刀桿上。上海切槽車刀哪家好</p><p
