style="text-indent:25px">90度外圓車刀簡(jiǎn)稱偏刀，按進(jìn)給方向不同分為左偏刀和右偏刀兩種，一般常用右偏刀。右偏刀，由右向左進(jìn)給。用來車削工件的外圓、端面和右臺(tái)階。它主便角較大，車削外圓時(shí)作用于工件的徑向力小，不易出現(xiàn)將工件頂彎的現(xiàn)象。一般用于半精加工。左偏刀，由左向右進(jìn)給。用于車削工件外圓和左臺(tái)階，也用于車削外徑較大而長(zhǎng)度短的零件（盤類零件）的端面。90 度外圓車刀有：前角、后角、主偏角、副偏角、刀尖角、刃傾角。前角；是切削的主要角度,前角越大,刀子就越銳利,切起來越省力,但前角太大了影響刀刃的強(qiáng)度。后角；是為了減少刀具與工件的摩擦,后角越大,摩擦愈小,但后角過大時(shí)則影響刀具的強(qiáng)度。主偏角；是在基面與進(jìn)給方向之間的夾角,它能改變徑向切削力與軸向切削力的比例。副偏角；副切削刃在基面上的投影和進(jìn)給方向之間的夾角,它影響已加工表面的光潔度,并能減少副切削刃與工件的摩擦。刀尖角；主切削刃與副切削刃在基面上投影之間的夾角,它影響刀尖強(qiáng)度及散熱性能。刃傾角；在切削平面內(nèi)主刀刃和基面的夾角,它影響切屑的流出方向及刀尖的強(qiáng)度</p><p 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)，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(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。車刀的切削部分由主切削刃、副切削刃、前刀面、主后刀面和副后刀面，刀尖角組成。</p><div

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(dòng)；（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(dòng)。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(dòng)車刀的尾部。磨刀安全知識(shí):(1）刃磨刀具前，應(yīng)首先檢查砂輪有無(wú)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(huì)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(duì)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)。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。南京陶瓷車刀加工廠家</p><p

style="text-indent:25px">車刀刃磨砂輪的選擇：砂輪的特性由磨料、粒度、硬度、結(jié)合劑和組織5個(gè)因素決定。（1)磨料，常用的磨料有氧化物系、碳化物系和高硬磨料系3種。船上和工廠常用的是氧化鋁砂輪和碳化硅砂輪。氧化鋁砂輪磨粒硬度低(HV2000-HV2400)、韌性大，適用刃磨高速鋼車刀，其中白色的叫做白剛玉，灰褐色的叫做棕剛玉。碳化硅砂輪的磨粒硬度比氧化鋁砂輪的磨粒高(Hv2800以上)。性脆而鋒利，并且具有良好的導(dǎo)熱性和導(dǎo)電性，適用刃磨硬質(zhì)合金。其中常用的是黑色和綠色的碳化硅砂輪。而綠色的碳化硅砂輪更適合刃磨硬質(zhì)合金車刀。天津內(nèi)孔車刀定制</p></p><br
