id="iu2djip" class="box"><p><p style="text-indent:25px">車刀的刃磨的方法：1、粗磨刀體上的副后角。磨副后面時，刀柄尾部應(yīng)向右轉(zhuǎn)過一個副偏角的角度，同時車刀底平面向砂輪方向傾斜一個比副后角大20的角度，具體刃磨方法與粗磨刀體上主后面大體相同，不同的是粗磨副后面時砂輪應(yīng)磨到刀尖處為止。也可同時磨出副偏角和副后角。2、粗磨前面。以砂輪的端面粗磨出車刀的前面，并在磨前面的同時磨出前角。3、磨斷屑槽，成型車刀定制。斷屑槽有兩種，一種是直線型，適用于切削較硬的材料；一種是圓弧型，適用于較軟的材料。手工刃磨的斷屑槽一般為圓弧型，須將砂輪的外圓和端面的交角處用修砂輪的金剛石筆修磨成相應(yīng)的圓弧，成型車刀定制。若刃磨出直線型斷屑槽，則砂輪的交角須修磨得很尖銳，成型車刀定制。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)。成型車刀定制</p><div

style="text-indent:25px">車刀種類和用途：機夾車刀機夾車刀是采用普通刀片，用機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：（1）刀片不經(jīng)過高溫焊接，避免了因焊接而引起的刀片硬度下降、產(chǎn)生裂紋等缺陷，提高了刀具的耐用度。（2）由于刀具耐用度提高，使用時間較長，換刀時間縮短，提高了生產(chǎn)效率。（3）刀桿可重復(fù)使用，既節(jié)省了鋼材又提高了刀片的利用率，刀片由制造廠家回收再制，提高了經(jīng)濟效益，降低了刀具成本。（4）刀片重磨后，尺寸會逐漸變小，為了恢復(fù)刀片的工作位置，往往在車刀結(jié)構(gòu)上設(shè)有刀片的調(diào)整機構(gòu)，以增加刀片的重磨次數(shù)。（5）壓緊刀片所用的壓板端部，可以起斷屑器作用?？赊D(zhuǎn)位車刀可轉(zhuǎn)位車刀是使用可轉(zhuǎn)位刀片的機夾車刀。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，直到刀片上所有切削刃均已用鈍，刀片才報廢回收。更換新刀片后，車刀又可繼續(xù)工作。成型車刀定制綠色的碳化硅砂輪更適合刃磨硬質(zhì)合金車刀。</p><div

style="text-indent:25px">與焊接車刀比較,可轉(zhuǎn)位車刀有什么優(yōu)缺點：1，焊接刀：價格低，可以隨意的磨出自己想要的形狀。使用壽命不長。對于難加工零件比較吃力，對人員專業(yè)素質(zhì)要求比較高。個人認(rèn)為適合普通機床普通精度的小批量生產(chǎn)。2.機夾刀：價格較高，形狀是標(biāo)準(zhǔn)的，如果工件有臨時變化那又要重新買了，因為這不能重磨。由于不需要磨刀所以工人上手比較快，適合于大批量高精度的數(shù)控加工。數(shù)控刀具必然是發(fā)展的一個方向，當(dāng)你的刀具選好后，你的效益會成倍的增加。但焊接刀具也不會消失的，因為還要應(yīng)對一些試制和機修等等突發(fā)的加工。</p><p style="text-indent:25px">車刀材料應(yīng)具備的性能刀具材料是指刀具切削部分的材料。金屬切削時，刀具切削部分直接和工件及切屑相接觸，承受著很大的切削壓力和沖擊，并受到工件及切屑的劇烈摩擦，產(chǎn)生很高的切削溫度。因此，刀具材料應(yīng)具備一定的性能。1.足夠的硬度一般來說，刀具材料的硬度必須高于被切工件材料的硬度，常溫硬度要求60HRC以上，除此之外，還必須具備較高的高溫硬度（熱硬性）和顯微硬度（金相組織硬度）2.高耐磨性和耐熱性刀具材料的耐磨性是指抵抗磨損的能力。一般說，刀具材料硬度越高，耐磨性也越好，但材料的耐磨性不單純?nèi)Q于材料的硬度，也并非材料越硬耐磨性越高。因為硬度過高，內(nèi)應(yīng)力增加，可能會加快表層的破壞，使耐磨性降低。刀片夾緊可靠應(yīng)保證刀片、刀墊、刀桿接觸面緊密貼合。</p><div

style="text-indent:25px">可轉(zhuǎn)位車刀刀片的夾緊特點與要求：（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，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。對小尺寸刀具結(jié)構(gòu)要緊湊。在滿足以上要求時，盡可能使結(jié)構(gòu)簡單，制造和使用方便。按結(jié)構(gòu)可分為整體車刀、焊接車刀、機夾車刀、可轉(zhuǎn)位車刀和成型車刀。成型車刀定制</p><p style="text-indent:25px">有利于推廣新技術(shù)、新工藝可轉(zhuǎn)位刀有利于推廣使用涂層、陶瓷等新型刀具材料。成型車刀定制</p><p style="text-indent:25px">車刀是指用于車削加工零件的一種刀具。車刀用于各種車床上，加工外圓、內(nèi)孔、端面、螺紋、車槽等。任何刀具都由刀頭和刀柄兩部分構(gòu)成。刀頭用于切削，刀柄用于裝夾。雖然用于切削加工的刀具種類繁多，但刀具切削部分的組成確有共同點。車刀的切削部分可看作是各種刀具切削部分較基本的形態(tài)。車刀的切削部分由主切削刃、副切削刃、前面、后面和副后面等組成。前面(前刀面)是指刀具上切屑流出的表面；后面(后刀面)是指刀具上與工件過渡表面相對的刀面；副后面(副后刀面)是指刀具上與工件新形成的表面相對的刀面；主切削刃是指前面與后面形成的交線，在切削中承擔(dān)主要的切削任務(wù)；副切削刃是指前面與副后面形成的交線，它參與部分的切削任務(wù)；刀尖是指主切削刃與副切削刃匯交的交點或一小段切削刃。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。負前角的平面型適用于加工高強度鋼和粗切鑄鋼件的硬質(zhì)合金車刀。帶倒棱的平面型是在正前角平面上磨有負倒棱以提高切削刃強度，適用于加工鑄鐵和一般鋼件的硬質(zhì)合金車刀。成型車刀定制</p></p><br
