针对机械密封加工的关键工序，即端面研磨中的问题，探讨了提高机械密封研磨面形精度的方法。通过控制研磨参数，使得磨具磨损均匀，从而保证磨具面形精度。得出了保证磨具均匀磨损的条件，分析了有关影响因素。根据这一理论设计磨具，选择研磨参数，进行实验，取得了很好的效果。 Aiming at the key process of mechanical seal machining, which is the problem of face grinding, the method to improve the precision of grinding surface of mechanical seal was discussed. By controlling the grinding parameters, making the abrasive wear uniform, so as to ensure the accuracy of abrasive surface shape. Obtained to ensure uniform abrasive wear conditions, analysis of the impact of factors. According to this theory, the design of abrasive tools, grinding parameters, experiments, and achieved good results.
