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(kāi)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(jī)夾車刀是采用普通刀片，用機(jī)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(diǎn)：（1）由于刀具耐用度提高，使用時(shí)間較長(zhǎng)，換刀時(shí)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(jī)械夾固式車刀特點(diǎn)（1）刀片不經(jīng)過(guò)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(huì)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(jī)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(jī)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(bào)廢回收。更換新刀片后，車刀又可繼續(xù)工作。徐州整體車刀報(bào)價(jià)車刀的工作部分就是產(chǎn)生和處理切屑的部分。</p><div

邊斜角：從刀頂面自切削邊向另一邊傾斜，此傾斜面和水平面所成角度為邊斜角。此角度是使切屑脫離工作物的角度，使排屑容易并獲得有效之車削。切削一般金屬，高速鋼車刀此角度大約為10~14度，而碳化物車刀可為正傾角也可為負(fù)傾角。5 刀端角：刀刃前端與刀柄垂直之角度。此角度的作用為保持刀刃前端與工件有一間隙避免刀刃與工件磨擦或擦傷已加工之表面。6 切邊角：刀刃前端與刀柄垂直之角度，其作用為改變切層的厚度。同時(shí)切邊角亦可改變車刀受力方向，減少進(jìn)刀阻力，增加刀具壽命，因此一般粗車時(shí)，宜采用切邊角較大之車刀，以減少進(jìn)刀阻力，增加切削速度。7 刀鼻半徑：刀刃可以高點(diǎn)之刀口圓弧半徑。刀鼻半徑大強(qiáng)度大，用於大的切削深度，但容易產(chǎn)生高頻振動(dòng)。</p><p style="text-indent:25px">立方氮化硼刀片的性能及適合加工材質(zhì)?立方氮化硼刀片的硬度比陶瓷刀片高很多，由于硬度高，與金剛石并稱為超硬材料，常用來(lái)加工硬度高于RC48的材料，它有極好的高溫硬度--高達(dá)2000℃，盡管比硬質(zhì)合金刀片脆，但與陶瓷刀片相比，沖擊強(qiáng)度和抗破碎性能有明顯提高。此外，一些特制的立方氮化硼刀片（華超超硬BN-S10和BN-s20牌號(hào)）能抵御大余量粗加工的切屑負(fù)荷，并能承受間斷切削加工時(shí)的沖擊以及精加工時(shí)的磨損和切削熱，這些特點(diǎn)可以滿足用立方氮化硼刀片粗加工淬火鋼等難加工材料。?刀刃用鈍后可以轉(zhuǎn)位繼續(xù)使用，而且停車換刀時(shí)間短，因此取得了迅速發(fā)展。</p><div
