style="text-indent:25px">車刀的安裝與夾緊1.刀頭的焊接：刀片鑲焊工藝簡(jiǎn)介通過加熱、熔介焊料，冷卻使刀片與刀體結(jié)合，較好的焊接方式是高頻焊、帶焊料的要求是，其熔點(diǎn)應(yīng)高于切削溫度，工作時(shí)能保持刀片的結(jié)合強(qiáng)度，同時(shí)有較好的潤(rùn)濕性及導(dǎo)熱性，焊接刀片時(shí)一般用工業(yè)硼砂作溶劑，保護(hù)焊層表面不被氧化，焊接YT合金時(shí)，加入一些氟化鉀，可改善對(duì)合金的潤(rùn)濕性，提高溶劑溶解氟化鈦的能力。常用焊料有以下幾種;1)銅鎳合金或紫銅，它們的熔點(diǎn)約1000-2000攝氏度，可適應(yīng)切削溫度在700-900攝氏度的切削工作或大負(fù)荷切削。2）銅鋅合金或105焊料，它們的熔點(diǎn)約900-950攝氏度，可適應(yīng)切削溫度在600攝氏度左右的中負(fù)荷切削工作。銀銅合金或106、107焊料，它們的熔點(diǎn)約820攝氏度，適用于焊接低鈷高鈦合金，刀片焊接后，應(yīng)將車刀置于爐中或稻草灰中緩慢冷卻，以減少應(yīng)用。天津硬質(zhì)合金車刀定做所謂焊接式車刀，就是在碳鋼刀桿上按刀具幾何角度的要求開出刀槽。</p><div

style="text-indent:25px">車刀刃磨的方法：（1）人站立在砂輪機(jī)的側(cè)面，以防砂輪碎裂時(shí)，碎片飛出傷人；（2）兩手握刀的距離放開，兩肘夾緊腰部，以減小磨刀時(shí)的抖動(dòng)；（3）磨刀時(shí)，車刀要放在砂輪的水平中心，刀尖略向上翹約3°~8°，車刀接觸砂輪后應(yīng)作左右方向水平移動(dòng)。當(dāng)車刀離開砂輪時(shí)，車刀需向上抬起，以防磨好的刀刃被砂輪碰傷；（4）磨后刀面時(shí)，刀桿尾部向左偏過一個(gè)主偏角的角度；磨副后刀面時(shí)，刀桿尾部向右偏過一個(gè)副偏角的角度；（5）修磨刀尖圓弧時(shí)，通常以左手握車刀前端為支點(diǎn)，用右手轉(zhuǎn)動(dòng)車刀的尾部。磨刀安全知識(shí):(1）刃磨刀具前，應(yīng)首先檢查砂輪有無裂紋，砂輪軸螺母是否擰緊，并經(jīng)試轉(zhuǎn)后使用，以免砂輪碎裂或飛出傷人。2）刃磨刀具不能用力過大，否則會(huì)使手打滑而觸及砂輪面，造成工傷事故。3)磨刀時(shí)應(yīng)戴防護(hù)眼鏡，以免砂礫和鐵屑飛入眼中。4）磨刀時(shí)不要正對(duì)砂輪的旋轉(zhuǎn)方向站立，以防意外。5）磨小刀頭時(shí)，必須把小刀頭裝入刀桿上。6）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(dāng)。</p><p style="text-indent:25px">車刀刀片特點(diǎn)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(dòng)，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(duì)小尺寸刀具結(jié)構(gòu)要緊湊。在滿足以上要求時(shí)，盡可能使結(jié)構(gòu)簡(jiǎn)單，制造和使用方便。車刀前角γo根據(jù)工件材料的成分和強(qiáng)度來選取，切削強(qiáng)度較高的材料時(shí)，應(yīng)取較小的值。</p><div

style="text-indent:25px">車刀在結(jié)構(gòu)上可分為整體車刀、焊接裝配式車刀和機(jī)械夾固刀片的車刀。徐州新型車刀批發(fā)</p><p style="text-indent:25px">如何選外圓車刀,螺紋車刀,內(nèi)孔車刀：外圓車刀分2種一種是90度外圓車刀和75度外圓車刀。要是比較籠統(tǒng)的說就是75度刀適合初加工 90度刀一般是半精加工和精加工（有時(shí)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(shí)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(shí)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(shí)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(gè)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徐州新型車刀批發(fā)</p></p><br
