style="text-indent:25px">十八世紀(jì)30年代，為了適應(yīng)鐘表、自行車、縫紉機(jī)等零件淬硬后的加工，英國(guó)、德國(guó)和美國(guó)分別研制出使用天然磨料砂輪的磨床。這些磨床是在當(dāng)時(shí)現(xiàn)成的機(jī)床如車床、刨床等上面加裝磨頭改制而成的，它們結(jié)構(gòu)簡(jiǎn)單，江蘇屹亞有限公司出口內(nèi)圓數(shù)控磨床與時(shí)俱進(jìn)，江蘇屹亞有限公司出口內(nèi)圓數(shù)控磨床與時(shí)俱進(jìn)，剛度低，磨削時(shí)易產(chǎn)生振動(dòng)，要求操作工人要有很高的技藝才能磨出精密的工件，江蘇屹亞有限公司出口內(nèi)圓數(shù)控磨床與時(shí)俱進(jìn)。1876年在巴黎博覽會(huì)展出的美國(guó)布朗-夏普公司制造的wan能外圓磨床，是shou次具有現(xiàn)代磨床基本特征的機(jī)械。它的工件頭架和尾座安裝在往復(fù)移動(dòng)的工作臺(tái)上，箱形床身提高了機(jī)床剛度，并帶有內(nèi)圓磨削附件。</p><div

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(kāi)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(kāi)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。</p><div
