（3） 若换向器表面出现粗糙、烧焦等现象时可用“0”号砂布在旋转着的换向器表面进行细致研磨。若换向器表面出现过于粗糙不平、不圆或有部分凹进现象时应将换向器进行车削，车削速度不大于1.5m/s，车削深度及每转进刀量均不大于0.1mm，车削时换向器不应有轴向移动。
（4） 换向器表面磨损很多时，或经车削后，发现云母片有凸出现象，应以铣刀将云母片铣成1~1.5mm的凹槽。
（5） 换向器车削或云母片下刻时，须防止铜屑、灰尘侵入电枢内部。因为要将电枢线圈端部及接头片覆盖。加工完毕后用压缩空气做清洁处理。

从锁具材料及从标准看怎样挑选门窗锁具材料人们选购锁具时，普遍均担心锁具不耐用或用不了多久表面便生锈或氧化。这个问题是关系到使用的材料及表面处理问题。从耐用的角度看，的材料应是不锈钢，尤其是用作表面材料，越用越光亮。其强度好、耐腐蚀性强、颜色不变。但不锈钢也有多种，主要可分为铁素体和奥氏体。铁素体不锈钢有磁性，俗称不锈铁，时间长，环境不好也会生锈，只有奥氏体不锈钢才不会生锈，鉴别办法很简单，用磁铁一试即可鉴别。
