由于弹性胀套具有其特殊的优点被机械加工中广泛应用。胀套加工中的关键即内锥面对外圆的跳动不易保证,常被一些企业所困扰。生产中有一种特殊胀套,如图1。胀套为双向15°内锥面,对外圆的跳动公差为0.005,按通常加工工艺不可能保证工件合格。针对该工件的特点,采取了新的粘接加工的方法。粗加工略,以热处理后工艺为例。 （1）热处理后由无心磨床磨外圆至φ43.72_(-0.02)~0,各件尺寸公差不大于0.001mm。
Due to the elastic expansion sleeve has its special advantages are widely used in machining. Expansion sets the key to the processing of the inner cone beating the outer circle is not easy to guarantee, often troubled by some companies. Production of a special expansion, as shown in Figure 1. Expansion sleeve bi-directional 15 ° cone, the beating tolerance of the outer circle of 0.005, according to the normal processing technology can not guarantee the workpiece qualified. In response to the characteristics of the workpiece, has taken a new method of bonding process. Roughing slightly to the heat treatment process as an example. (1) After the heat treatment by the centerless grinder grinding cylindrical to φ43.72 _ (- 0.02) ~ 0, each piece size tolerance of not more than 0.001mm.
