<p> 3）如果磨床保持架是在握持中段位置磨礪膠輥，軸承芯子應(yīng)選擇無(wú)心磨床生產(chǎn)的芯子；辨認(rèn)是否為無(wú)心磨床生產(chǎn)的芯子，簡(jiǎn)單的辦法是看芯子兩端，應(yīng)不帶前列孔。 </p> <p> 4）對(duì)軸承要先進(jìn)行檢查，看是否靈活、是否洗凈油污、軸承間隙大小是否合適、軸承表面有無(wú)傷痕及雜物。 </p> <p> 5）套制膠輥時(shí)，比較好選用立式套機(jī)，調(diào)好中心線(xiàn)，壓力要適中，并檢查套機(jī)探頭是否磨損，要定期對(duì)設(shè)備進(jìn)行保養(yǎng)和調(diào)校。 </p> <p> 6）套制完成后要檢查軸承兩端是否有金屬屑，如有要及時(shí)清理。 </p> <p> 7）加油封蓋時(shí)應(yīng)使用**工具，以免油堵塞在兩端。 </p> <p> 8）軸承芯子加油應(yīng)適量，上車(chē)4個(gè)月后應(yīng)重新補(bǔ)油。 **擠干輥數(shù)控鏜床上采用成型刀具加工各斷面處的槽形。</p><div style="width:100%;text-align: center;"><img style="max-width:
