style="text-indent:25px">主軸加工的主要問題是如何保證主軸支承軸頸的尺寸、形狀、位置精度和表面粗糙度，主軸前端內(nèi)、外錐面的形狀精度、表面粗糙度以及它們對支承軸頸的位置精度。主軸支承軸頸的尺寸精度、形狀精度以及表面粗糙度要求，可以采用精密磨削方法保證。磨削前應(yīng)提高精基準(zhǔn)的精度。保證主軸前端內(nèi)、外錐面的形狀精度、表面粗糙度同樣應(yīng)采用精密磨削的方法。為了保證外錐面相對支承軸頸的位置精度，以及支承軸頸之間的位置精度，通常采用組合磨削法，在一次裝夾中加工這些表面，機(jī)床上有兩個**的砂輪架，精磨在兩個工位上進(jìn)行，工位Ⅰ精磨前、后軸頸錐面，工位Ⅱ用角度成形砂輪，磨削主軸前端支承面和短錐面。主軸外圓表面的加工，應(yīng)該以頂部尖孔作為統(tǒng)一的定位基準(zhǔn)。但在主軸的加工過程中，隨著通孔的加工，作為定位基準(zhǔn)面的中心孔消失，工藝上常采用帶有中心孔的錐堵塞到主軸兩端孔中，讓錐堵的頂部尖孔起附加定位基準(zhǔn)的作用。無錫精密軸承制造外表面磨削砂輪線速度達(dá)120m/s，內(nèi)表面磨削線速度達(dá)60m/s～80m/s。</p><div

style="text-indent:25px">立方氮化硼磨料簡稱CBN磨料，由其制造的砂輪稱為CBN砂輪，其主要具有下列特征： ⑴ 硬度高，導(dǎo)熱率高，熱穩(wěn)定性好，可承受1300～1500℃高溫。 ⑵ 耐用性高，磨耗小，磨削比可達(dá)4000～10000（磨削比是指磨削過程去除工件材料量與砂輪磨損量的比值）而普通剛玉砂輪*為50～80。 ⑶ 磨削力小，磨削熱小，加工工件應(yīng)力小，表層應(yīng)力薄或沒有。⑷ 輔助時(shí)間（修整砂輪、更換砂輪）減少。對我國軸承行業(yè)來說，利用CBN進(jìn)行套圈磨削加工是種新的加工技術(shù)，應(yīng)用前景非常廣闊。由于CBN砂輪具有良好的加工特點(diǎn)，利用CBN砂輪進(jìn)行軸承套圈磨削國外早已進(jìn)行了研制并應(yīng)用于生產(chǎn)中。</p><p style="text-indent:25px">在砂輪包括整形與修銳的修整之前，保證主軸軸承在一定的溫度下(如通常的砂輪磨削狀態(tài))是很重要的。這樣可避免損傷零件幾何形狀以及砂輪和修整工具的非正常磨損。對于修整用的工具必須小心處理，因?yàn)樗话阌少|(zhì)硬、耐磨但又很脆的金剛石材料制成，且對因輕微碰撞、受力引起微小裂紋和破碎都非常敏感。因?yàn)榻饎偸纹鞅旧砭褪且话压ぞ?，需保持非常鋒利。使用一個磨鈍了的修整工具來修整砂輪表面，會使砂輪變鈍。為了保持一個高質(zhì)量和鋒利的金剛石修整工具，每隔一定時(shí)間，需要1/8圈地旋轉(zhuǎn)單點(diǎn)或帶錐尖的修整工具。旋轉(zhuǎn)次數(shù)可根據(jù)修整情況決定，根據(jù)經(jīng)驗(yàn)，建議每天旋轉(zhuǎn)一次。對于鑿子頭和成型的修整工具，一般需在它們磨鈍前180°地旋轉(zhuǎn)一次。大多數(shù)外圓磨床是將零件和砂輪置于一個水平線上。零件外圓的至高點(diǎn)與砂輪外圓的至高點(diǎn)稱為零件/砂輪接觸點(diǎn)，金剛石修整工具應(yīng)盡可能地在接近零件/砂輪接觸點(diǎn)處修整砂輪。對于內(nèi)圓磨床用砂輪，將金剛石修整工具接近砂輪外圓的至高點(diǎn)(即磨孔時(shí)零件/砂輪接觸點(diǎn))進(jìn)行修整，這一點(diǎn)更為重要。高速主軸單元是高速磨床更為關(guān)鍵的部件。</p><div

style="text-indent:25px">超精研工整個過程包括**的區(qū)分明顯的三個階段：修整、恒定切削、磨光（也有分為：切削階段或自銳階段、半切削階段、光整階段）。并且整個過程在基本工藝參數(shù)（如切削速度、油石壓力和硬度、振蕩頻率、磨料種類、工件材料以及潤滑冷卻液等）不變的條件下自動完結(jié)。超精研加工的優(yōu)點(diǎn)：能有效的減小圓形偏差（主要是波紋度）、能有效地改善滾道母線的直線性或加工成所需要的凸度形狀、能去除磨削變質(zhì)層，降低表面粗糙度值、能使表面具有殘余的壓應(yīng)力、能夠在加工表面形成紋理均勻細(xì)膩的、較理想的交叉紋路、能使工作接觸支承面積增大。超精加工對滾動軸承工作性能的影響有哪些？1、提高軸承的旋轉(zhuǎn)精度，減低軸承的振動和噪聲。2、提高軸承的承載能力。3、提高軸承的潤滑效果，減小磨損。4、減小軸承工作時(shí)的發(fā)熱。套圈是滾動軸承的重要零件。上海大型軸承加工</p><p style="text-indent:25px">磨削加工對于加工成形機(jī)理更復(fù)雜，影響加工精度的因素眾多。上海大型軸承加工</p><p style="text-indent:25px">軸承是當(dāng)代機(jī)械設(shè)備中一種重要零部件，它的主要功能是支撐機(jī)械旋轉(zhuǎn)體，降低其運(yùn)動過程中的摩擦系數(shù)，并保證其回轉(zhuǎn)精度。滾動軸承一般由外圈、內(nèi)圈、滾動體和保持架四部分組成。按滾動體的形狀，滾動軸承分為球軸承和滾子軸承兩大類。雖然滾動軸承類型眾多，其結(jié)構(gòu)型式、公差等級、材料選用、加工方法存在差異，但其基本制造過程類似，下面簡單介紹下軸承制造工藝順序：（1）軸承零件制造-軸承零件檢查-軸承零件退磁、清洗、防銹—軸承裝配-軸承成品檢查—軸承成品退磁、清洗-軸承成品涂油包裝斗成品入庫。（2）套圈是滾動軸承的重要零件，由于滾動軸承的品種繁多，使得不同類型軸承的套圈尺寸、結(jié)構(gòu)、制造使用的設(shè)備、工藝方法等各不相同。又由于套圈加工工序多、工藝復(fù)雜、加工精度要求高，因此套圈的加工質(zhì)量對軸承的精度、使用壽命和性能有著重要的影響。上海大型軸承加工</p><p
