style="text-indent:25px">可轉(zhuǎn)位車刀的應(yīng)用日益較廣，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）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。（2）壓緊刀片所用的壓板端部，可以起斷屑器作用。機械夾固式車刀特點（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。（3）刀片重磨后，尺寸會逐漸變小，為了恢復刀片的工作位置，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)。（4）壓緊刀片所用的壓板端部，可以起斷屑器作用。四、可轉(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。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。</p><div

2．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。車刀是用于車削加工的、具有一個切削部分的刀具。蘇州D型車刀定制</p><p

style="text-indent:25px">車刀材料應(yīng)具備的性能：3.足夠的強度和韌性（堅韌性）強度是指抵抗切削力的作用而不至于崩刃或刀桿折斷所應(yīng)具備的性能，一般用抗彎強度來表示。沖擊韌性是指刀具材料在斷續(xù)切削或有沖擊的工作條件下保證不崩刃的能力。強度越高，承受切削抗力的能力越大，刃口崩損的傾向小。4.良好的導熱性刀具材料的導熱性用熱導率（單位為W/m·K）來表示。熱導率大，表示導熱性好，切削時產(chǎn)生的熱量容易傳導出去，從而降低切削部分的溫度、減輕刀具磨損。5.較好的工藝性和經(jīng)濟性為便于加工制造，要求刀具材料有良好的工藝性能，即具有良好的可加工性能、可磨削性、高溫塑性、鍛造性、焊接性及熱處理工藝性等。工藝性能差的材料不宜制造刀具。6.良好的抗粘接性和化學穩(wěn)定性抗粘接性防止工件與刀具材料分子間在高溫高壓作用下互相吸附產(chǎn)生粘接。化學穩(wěn)定性指刀具材料在高溫下，不易與周圍介質(zhì)發(fā)生化學反應(yīng)。刀具材料的種類繁多，且隨著科學技術(shù)的發(fā)展，新的刀具材料也不斷出現(xiàn)，常用刀具材料可分為四大類：工具鋼、硬質(zhì)合金、陶瓷及超硬材料。上海D型車刀批發(fā)</p></p><br
