style="text-indent:25px">車刀刃磨砂輪的選擇（2)粒度：粒度表示磨粒大小的程度。以磨粒能通過每英寸長度上多少個孔眼的數(shù)字作為表示符號。例如60粒度是指磨粒剛可通過每英寸長度上有60個孔眼的篩網(wǎng)。因此，數(shù)字越大則表示磨粒越細(xì)。粗磨車刀應(yīng)選磨粒號數(shù)小的砂輪，精磨車刀應(yīng)選號數(shù)大(即磨粒細(xì))的砂輪。船上常用的粒度為46號—臺0號的中軟或中硬的砂輪。（3)硬度：砂輪的硬度是反映磨粒在磨削力作用下，從砂輪表面上脫落的難易程度。砂輪硬，即表面磨粒難以脫落；砂輪軟，表示磨粒容易脫落，杭州合金車刀哪家好。砂輪的軟硬和磨粒的軟硬是兩個不同的概念，必須區(qū)分清楚。刃磨高速鋼車刀和硬質(zhì)合金車刀時應(yīng)選軟或中軟的砂輪。另外，杭州合金車刀哪家好，在選擇砂輪時還應(yīng)考慮砂輪的結(jié)合劑和組織。船上和工廠一般選用陶瓷結(jié)合劑(代號A)和中等組織的砂輪，杭州合金車刀哪家好。綜上所述，我們應(yīng)根據(jù)刀具材料正確選用砂輪。刃磨高速鋼車刀時，應(yīng)選用粒度為46號到60號的軟或中軟的氧化鋁砂輪。刃磨硬質(zhì)合金車刀時，應(yīng)選用粒度為60號到80號的軟或中軟的碳化硅砂輪，兩者不能搞錯。刀刃用鈍后可以轉(zhuǎn)位繼續(xù)使用，而且停車換刀時間短，因此取得了迅速發(fā)展。杭州合金車刀哪家好</p><div

style="text-indent:25px">陶瓷刀片與立方氮化硼刀片應(yīng)用區(qū)別??立方氮化硼在材料學(xué)中雖歸于陶瓷大類，但由于CBN，SIN，Al2O3，SiN材料的性能差異，陶瓷刀片不及立方氮化硼刀片的韌性和硬度。所以根據(jù)其硬度和韌性的差異，在切削硬度低于50HRC以下和小切深小進(jìn)給情況下的淬火鋼工件時，陶瓷刀片是較好的選擇。立方氮化硼刀片適合于工件硬度高于50HRC情況。除此之外，在相同后刀面磨損情況下，立方氮化硼刀片切削后的工件表面殘余應(yīng)力也比陶瓷刀片相對穩(wěn)定。所以在陶瓷刀片的適合加工領(lǐng)域中，也可選用立方氮化硼刀片，用戶可根據(jù)成本效益和加工需求，來確定哪一種刀片材料更經(jīng)濟(jì)。車刀刃磨時磨主后刀面，同時磨出主偏角及主后角。</p><div

90度刀一般是半精加工和精加工（有時候人們也把90度車刀的角度磨的比較小、并不磨斷削槽也用來粗加工)。螺紋車刀也分2大類內(nèi)螺紋車刀和外螺紋車刀。如果按照刀的材料分為高速鋼螺紋車刀與硬質(zhì)合金螺紋車刀。硬質(zhì)合金螺紋車刀的特點(diǎn)是硬度高同時抗震型也比高速鋼要好所以它適合高速切削，做批量生產(chǎn)的時候一般選擇它。高速鋼車刀雖然只能低速切削可是它加工出來的光潔度要高的多。初學(xué)和考試的時候選擇的比較多。內(nèi)孔車刀還是分2種通孔車刀與盲孔車刀。這2個車刀沒什么大的介紹但是盲孔車刀能加工有通孔的工件，可是通孔車刀不能加工有盲孔的工件車刀的切削部分和柄部(即裝夾部分)的結(jié)合方式主要有整體式、焊接式、機(jī)械夾固式和焊接-機(jī)械夾固式。徐州切槽車刀銷售公司</p><p style="text-indent:25px">車刀的工作部分就是產(chǎn)生和處理切屑的部分。杭州合金車刀哪家好</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(dāng)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(biāo)準(zhǔn)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，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。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(dāng)伸出量大于4倍或加工剛性差的工件時，應(yīng)選用帶有減振機(jī)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。杭州合金車刀哪家好</p></p><br
