style="text-indent:25px">磨床系指用磨具或磨料加工工件各種表面機(jī)床。一般用于對(duì)零件淬硬表面做磨削加工。通常，磨具旋轉(zhuǎn)為主運(yùn)動(dòng)，工件或磨具移動(dòng)為進(jìn)給運(yùn)動(dòng)，其應(yīng)用很廣、加工精度高、表面粗糙度Ra值小，磨床可分為十余種： ⑴外圓磨床：普通型基型系列，上海高精度外圓數(shù)控磨床占地面積小，主要用于磨削圓柱形圓錐形外表面磨床。 ⑵內(nèi)圓磨床：普通型基型系列，主要用于磨削圓柱形圓錐形內(nèi)表面磨床。 ⑶坐標(biāo)磨床：具有精密坐標(biāo)定位裝置內(nèi)圓磨床。 ⑷無(wú)心磨床：工件采用無(wú)心夾持，一般支承導(dǎo)輪托架之間，由導(dǎo)輪驅(qū)動(dòng)工件旋轉(zhuǎn)，主要用于磨削圓柱形表面磨床。 ⑸平面磨床：主要用于磨削工件平面磨床。 ⑹砂帶磨床：用快速運(yùn)動(dòng)砂帶進(jìn)行磨削磨床。 ⑺珩磨機(jī)：用于珩磨工件各種表面磨床。 ⑻研磨機(jī)：用于研磨工件平面或圓柱形內(nèi)，外表面磨床。 ⑼導(dǎo)軌磨床：主要用于磨削機(jī)床導(dǎo)軌面磨床。 ⑽工具磨床：用于磨削工具磨床。 ⑾多用磨床：用于磨削圓柱、圓錐形內(nèi)，上海高精度外圓數(shù)控磨床占地面積小、外表面或平面，并能用隨動(dòng)裝置及附件磨削多種工件磨床，上海高精度外圓數(shù)控磨床占地面積小。 ⑿**磨床：從事對(duì)某類零件進(jìn)行磨削**機(jī)床。按其加工對(duì)象又可分為：花鍵軸磨床、曲軸磨床、凸輪磨床、齒輪磨床、螺紋磨床、曲線磨床等。上海高精度外圓數(shù)控磨床占地面積小</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

內(nèi)圓的磨削與外圓磨削不同，內(nèi)圓磨削時(shí)，砂輪的直徑受到工件孔徑的限制，一般較小，故砂輪磨損較快，需經(jīng)常修整和更換。內(nèi)圓磨使用的砂輪要比外圓磨使用的砂輪軟些，這是因?yàn)閮?nèi)圓磨時(shí)砂輪和工件接觸的面積較大。另外，砂輪軸直徑比較小，懸伸長(zhǎng)度較大，剛性很差，故磨削深度不能大，而降低了生產(chǎn)率。 </p> <p> <br /> </p> <p> 工件兩端尺寸較大呈鞍型 </p> <p> 解析原因：外圓磨床的砂輪余越出工件端面太少；外圓磨床工作臺(tái)停留時(shí)間太短；磨細(xì)長(zhǎng)軸時(shí)，前列頂?shù)奶o；外圓磨床的中心架水平撐塊壓力太大； </p> <p>

大多數(shù)外圓磨床是將零件和砂輪置于一個(gè)水平線上。零件外圓的比較高點(diǎn)與砂輪外圓的比較高點(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(duì)于內(nèi)圓磨床用砂輪，將金剛石修整工具接近砂輪外圓的比較高點(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。　為減少修整時(shí)間，好象總存在一種想選擇大些修除深度的誘惑。這是一種極其錯(cuò)誤的想法。必須選擇**合適的修除深度對(duì)砂輪進(jìn)行修整。選擇太大的修除深度，會(huì)產(chǎn)生高的切削溫度，減少修整器的使用壽命，還會(huì)將有用的砂輪層切除。**終結(jié)果是使修整器和砂輪兩者受損，適得其反。比較好的修整量為經(jīng)幾次修除后，既能恢復(fù)砂輪的幾何外形，又能恰好產(chǎn)生出良好的磨削鋒刃為準(zhǔn)則。使用單點(diǎn)修整工具，應(yīng)以10-15o的軸心線傾斜角接觸砂輪的直徑方向。這樣將使單點(diǎn)修整工具在定期轉(zhuǎn)動(dòng)時(shí)，產(chǎn)生一個(gè)削尖的作用。以多點(diǎn)接觸的修整工具不需要傾斜這一角度。改為用修整工具的整個(gè)端面與砂輪表面接觸?！?　橫向移動(dòng)速度是修整工具在修整中通過(guò)砂輪表面的速度。它對(duì)加工零件要求的表面粗糙度和金屬切削率都起有關(guān)鍵的作用。橫向移動(dòng)速度太慢，將會(huì)堵塞砂輪，損害零件的表面粗糙度和金屬切削率。</p><p> 外圓磨削主要在外圓磨床上進(jìn)行，用以磨削軸類工件的外圓柱、外圓錐和軸肩端面。 </p> <p> 磨削時(shí)，工件低速旋轉(zhuǎn)，如果工件同時(shí)作縱向往復(fù)移動(dòng)并在縱向移動(dòng)的每次單行程或雙行程后砂輪相對(duì)工件作橫向進(jìn)給，稱為縱向磨削法。 </p> <p> 如果砂輪寬度大于被磨削表面的長(zhǎng)度，則工件在磨削過(guò)程中不作縱向移動(dòng)，而是砂輪相對(duì)工件連續(xù)進(jìn)行橫向進(jìn)給，稱為切入磨削法。 </p> <p> 一般切入磨削法效率高于縱向磨削法。如果將砂輪修整成成形面，切入磨削法可加工成形的外表面。 </p><div style="width:100%;text-align:

現(xiàn)在只講解**基礎(chǔ)的解決方法。磨削損傷實(shí)際上是由于磨削溫度過(guò)高，引起被磨削表面層的金相組織變化而致。磨削損傷一般有兩種情況，第一種是由于磨削溫度超過(guò)材料的相變溫度，往往造成“二次淬火”損傷；第二種是磨削溫度雖很高，但沒(méi)有超過(guò)材料相變溫度，往往會(huì)造成“回火”損傷。　　解決磨削損傷問(wèn)題的方法，是在磨削中充分澆注磨削液的同時(shí)，采取使用開槽砂輪的方法進(jìn)行斷續(xù)磨削。它在磨削過(guò)程中，砂輪槽經(jīng)過(guò)磨削區(qū)時(shí)沒(méi)有切削工件，這就相對(duì)減少了砂輪的滑擦和切削。斷續(xù)磨削的開槽砂輪具有較好的自銳性，砂輪自銳性好就意味著砂輪表面上的磨粒經(jīng)常處于鋒利狀態(tài)，磨削中切屑的變形就會(huì)減小，砂輪與工件之間的摩擦也減小，磨削過(guò)程中消耗的切削性能也相應(yīng)減少，所以切削力和切削溫度都能減小。　　斷續(xù)磨削的磨削溫度比普通磨削低，還有一個(gè)原因，就是它能減少或中斷熱量的積累。磨削損傷主要是由于磨削溫度引起工件表面層的金相組織變化，在磨削過(guò)程中，只要能減少切削熱的產(chǎn)生或及時(shí)將切削熱傳遞出去，都能有效地減輕或避免磨削損傷。普通磨削時(shí)，砂輪與工件始終接觸著，磨削前面工件產(chǎn)生的熱量，就會(huì)傳遞到后面即將被磨削的工件部分上。上海高精度外圓數(shù)控磨床占地面積小</p><p
