style="text-indent:25px">用磨料磨具(砂輪、砂帶、油石和研磨料等)為工具進(jìn)行切削加工的機(jī)床,統(tǒng)稱為磨床（英文為 Grinding machine),它們是因精加工和硬表面的需要而發(fā)展起來的。磨床種類很多,主要有:外圓磨床、內(nèi)圓磨床、平面磨床、工具磨床和用來磨削特定表面和工件的專門化磨床,如花鍵軸磨軸磨床、凸輪軸磨床、曲軸磨床等。對外圓磨床來說,又可分為普通外圓磨床、***外圓磨床、無心外圓磨床、寬砂輪外圓磨床、端面外圓磨床等。以上均為使用砂輪作切削工具的磨床。此外,還有以柔性砂帶為切削工具的砂帶磨床，以油石和研磨劑為切削工具的精磨磨床等。磨床要有專人負(fù)責(zé)保養(yǎng)和使用，定期檢修，這樣才能確保機(jī)床是一直處于良好的狀態(tài)。浙江端面外圓磨床</p><p style="text-indent:25px">對于很多用戶來講，購買了磨床設(shè)備只懂得怎么用，卻往往忽視了機(jī)械維護(hù)這個環(huán)節(jié)。山西平面精密磨床</p><p style="text-indent:25px">主軸軸承系統(tǒng)的剛性是指在磨削力或傳動力作用下，主軸軸承抵抗變形的能力。通常以主軸前端的撓度來度量。過低的剛性會降低磨削生產(chǎn)率、加工精度和工件表面的粗糙度，引起直波形和螺旋線缺陷。在砂輪架主軸的設(shè)計(jì)中，因?yàn)檩S的中間部分只有一部分需要進(jìn)行精加工,以便安裝動靜壓軸承,其余部分則沒有什么特殊的加工要求。隨著磨料磨具的發(fā)展(如新型磨料立方碳化硼的岀現(xiàn),粘結(jié)劑及砂輪結(jié)構(gòu)的改進(jìn))及磨床結(jié)構(gòu)的改進(jìn),在磨削加工中采用了高速磨削,強(qiáng)力磨削,寬砂輪和多砂輪磨削以及其他的磨削工藝(如砂帶磨削、電解磨削),使磨削效率不斷提高。高速磨削是指將砂輪的線速度從目前的35m/s水平提高到50-60m/s。砂輪線速度提高后可以提高磨削效率及表面質(zhì)量,延長砂輪使用壽命。山西平面精密磨床</p></p><br
