G2CrNi2Mo滲碳鋼制圓錐滾子軸承外圈，在使用過程中出現開裂現象。由于該軸承產量高，使用部位關鍵，為避免再出現同樣的開裂現象，必須找出其產生失效的原因。本文通過宏觀分析、微觀分析、掃描電鏡的分析，就開裂的原因進行了討論。滲碳鋼制圓錐滾子軸承外圈開裂失效分析1.外圈開裂宏觀特征失效的滲碳鋼制圓錐滾子軸承外圈外表面除有一條貫通的、且與軸線平行的開裂裂紋外，還有兩條源自大裂縫的散射細裂紋。除兩端及中部非工作區外，套圈上有兩道大的磨損區，呈不同的亮白色光澤帶。

一般使用車床進行機械加工時，會發生所謂的振刀的場合大概有這幾種場合：利用成型刀片進行成形車削；細長圓桿的外圓車削；薄肉圓桿的外圓車削；箱形部品（如鈑金焊接結構件）車削；超硬材質切削；軸承已受損而繼續切削等。當振刀發生時，刀具、工件與車床的振動往往導致工廠內部有刺耳的噪音，而其振幅大小單邊達數十微米以上，有時其至高達1微米以上。這種振刀不僅造成刀具或工件的夾持變松之外，同時也因其嘈雜的噪音對操作人員造成不良的身心影響，而加工精度也因此無法達成客戶的要求，因此各工具機廠莫不戰戰兢兢地將振刀問題之排除視為莫大的挑戰。
