style="text-indent:25px">對(duì)于軸承套的加工工序來說，我們常見的就有兩種方法：一種是集中工序，另一種是分散工序。軸承套圈集中工序只用了一道工序就可完成一個(gè)或幾個(gè)套圈的車削加工。軸承套圈分散工序要分幾次裝夾才能完成一個(gè)套圈的車削加工。另外分散工序的工序多而且工藝路線比較長(zhǎng)，加工時(shí)間和工序間停貯、運(yùn)輸、檢查裝卸等時(shí)間都比較長(zhǎng)，一個(gè)套圈需經(jīng)多機(jī)、多工序、多次裝夾定位、多人操作和檢查，定位誤差大、加工精度差。增加了人員、財(cái)力、物力和能源的消耗。</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(dòng)過程中的摩擦系數(shù)，并保證其回轉(zhuǎn)精度。滾動(dòng)軸承一般由外圈、內(nèi)圈、滾動(dòng)體和保持架四部分組成。按滾動(dòng)體的形狀，滾動(dòng)軸承分為球軸承和滾子軸承兩大類。雖然滾動(dòng)軸承類型眾多，其結(jié)構(gòu)型式、公差等級(jí)、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(jiǎn)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(dòng)軸承的重要零件，由于滾動(dòng)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(duì)軸承的精度、使用壽命和性能有著重要的影響。如今國(guó)內(nèi)軸承業(yè)套圈磨削加工中應(yīng)用高速磨削技術(shù)，配套成功研制了高剛度、高轉(zhuǎn)速、大功率電主軸及高速砂輪。</p><div
