style="text-indent:25px">目前在套圈加工中成型方法主要有以下幾種：鍛造成型、車削成型、冷輾擴(kuò)成型和冷（溫）擠壓成型。（1）鍛造成型通過(guò)鍛造加工可以消除金屬內(nèi)在不足，改善金屬元素使金屬流線分布合理，金屬緊密度好。鍛造成型加工工藝普遍應(yīng)用于軸承成型加工中，常見(jiàn)的鍛造成型方法有：熱鍛加工、冷鍛加工、溫鍛加工。（2）沖壓成型工藝是一種能提高材料利用率，提高金屬元素致密性，保持金屬流線性的先進(jìn)工藝方法，它是一種無(wú)屑加工方法。采用沖壓工藝和鍛造成型工藝時(shí)，產(chǎn)品的精度除了受設(shè)備精度影響外，還要受成型模具精度的影響。（3）傳統(tǒng)的車削成型技術(shù)是使用**車床，采用集中工序法完成成型加工。一些外形復(fù)雜、精度要求高的產(chǎn)品正越來(lái)越多地采用數(shù)控車削成型技術(shù)。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。太原軸承**設(shè)備</p><p

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(guò)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(méi)有。⑷ 輔助時(shí)間（修整砂輪、更換砂輪）減少。對(duì)我國(guó)軸承行業(yè)來(lái)說(shuō)，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(guó)外早已進(jìn)行了研制并應(yīng)用于生產(chǎn)中。遼寧直線軸承生產(chǎn)廠家</p><p
