In view of the quality problems caused by the vibration of the middle rubber ring in the reform process of the central 〖JP2〗pin of a bogie, the processing method was studied from the aspects of processing equipment, tooling design and cutting tools, and finally〖JP〗 the vertical machining center with inner cooling function was chosen.A set of fixture was designed, boring tool and groove knife were combinated to solve the above problem. This scheme can improve the processing efficiency while ensuring the quality, so the method of solving the processing difficulty based on the cleverness of tooling design and the flexibility of equipment function is worthy of reference.
