id="k2syoca" class="box"><p><p style="text-indent:25px">如何選擇內(nèi)孔車刀，方法如下：1、刀柄截面形狀的選用。優(yōu)先選用圓柄車刀。由于圓柄車刀的刀尖高度是刀柄高度的二分之一，且柄部為圓形，有利于排屑，故在加工相同直徑的孔時圓柄車刀的剛性明顯高于方柄車刀，所以在條件許可時應(yīng)盡量采用圓柄車刀。在臥式車床上因受四方刀架限制，一般多采用正方形或矩形柄車刀。如用圓柄車刀，為使刀尖處于主軸中心線高度，當圓柄車刀頂部超過四方刀架的使用范圍時，可增加輔具后再使用。2、刀柄截面尺寸的選用。標準內(nèi)孔車刀已給定了可以小加工孔徑。對于加工可以大孔徑范圍，一般不超過比它大一個規(guī)格的車孔刀所定的可以小加工孔徑，徐州硬質(zhì)合金車刀價格，如特殊需要，也應(yīng)小于再大一個規(guī)格的使用范圍。3、刀柄形式的選用，徐州硬質(zhì)合金車刀價格。通常大量使用的是整體鋼制刀柄，這時刀桿的伸出量應(yīng)在刀桿直徑的4倍以內(nèi)。當伸出量大于4倍或加工剛性差的工件時，徐州硬質(zhì)合金車刀價格，應(yīng)選用帶有減振機構(gòu)的刀柄。如加工很高精度的孔，應(yīng)選用重金屬(如硬質(zhì)合金)制造的刀柄，如在加工過程中刀尖部需要充分冷卻，則應(yīng)選用有切削液送孔的刀柄。成形車刀是加工回轉(zhuǎn)體成形表面的**刀具。徐州硬質(zhì)合金車刀價格</p><div

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。南京外圓車刀訂制高速鋼刀具使用前需生產(chǎn)者自行刃磨，且刃磨方便，適于各種特殊需要的非標準刀具。</p><div

style="text-indent:25px">按結(jié)構(gòu)可分為整體車刀、焊接車刀、機夾車刀、切斷車刀、可轉(zhuǎn)位車刀和成形車刀等等。1、切斷車刀：切斷車刀切既窄且深的槽，排屑空間小，切屑極易堵塞，為了減小同已加工表面的摩擦，其切削部分的兩側(cè)必須磨有副偏角，因而根部的強度較大削弱。此外，切斷車刀在切近工件中心處時，切削速度趨近于零，不利于切削。2、成形車刀：成形車刀是加工回轉(zhuǎn)體成形表面的**刀具，其刃形是根據(jù)工件廓形設(shè)計的，可用在各類車床上加工內(nèi)外回轉(zhuǎn)體的成形表面。用成形車刀加工零件時可一次形成零件表面，操作簡便、生產(chǎn)率高，加工后能達到公差等級IT8～IT10、粗糙度為10～5μm，并能保證較高的互換性。</p><p

-2°～-10°。一般情況下后角取 6°～10°。主偏角κr根據(jù)工藝系統(tǒng)的剛性條件而定,一般取30°～75°,剛性差時取較大的值，在車階梯軸時，由于切削方式的需要取大于或等于90°。刀尖圓弧半徑rε和副偏角κr'一般按加工表面粗糙度的要求而選取。刃傾角γS則根據(jù)所要求的排屑方向和刀刃強度確定。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?？梢院唵蔚氖瞧矫嫘停敖堑钠矫嫘瓦m用于高速鋼車刀和精加工用的硬質(zhì)合金車刀。數(shù)控車床刀具種類從制造所采用的材料高速鋼刀具高速鋼通常是型坯材料。</p><div

style="text-indent:25px">內(nèi)孔車刀與外圓車刀相比有如下特點：1、由于尺寸受到孔徑的限制，裝夾部分結(jié)構(gòu)要求簡單、緊湊，夾緊件可以好不外露，夾緊可靠。2、刀桿懸臂使用，剛性差，為增強刀具剛性盡量選用大斷面尺寸刀桿，減少刀桿長度3、內(nèi)孔加工的斷屑、排屑可靠性比外圓車刀更為重要，因而刀具頭部要留有足夠的排屑空間。品種規(guī)格的選用：常用的車刀有三種不同截面形狀的刀柄，即圓柄、矩形柄和正方形柄。普通型和模塊式的圓柄車刀多用于車削加工中心和數(shù)控車床上。矩形和方形柄多用于普通車床。還有一些特殊用途的車孔刀，如柄部有切削液輸送孔的，柄部裝有減振機構(gòu)的和用于重金屬做刀柄的等，但是不常用。硬質(zhì)合金車刀在切削普通碳素鋼時前角取10°～15°。南京硬質(zhì)合金車刀定做</p><p

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，形狀是標準的，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。徐州硬質(zhì)合金車刀價格</p><p
