Abstract
Not only the corrugation wear of railroad rail causes vibration and noise, but also it is mentioned as one of the factors which are connected with the derailment. As this corrugation wear countermeasure, the method that a cup grinding stone is installed in the vertical spindle and that it rotates, and that it does the re-profiling has been used. However, the problems that the grinding distance per unit time is short and that it is difficult to get a smooth plane, and that it is expensive, are also being taken up in this method. Then , in this study, the re-profiling equipment that facing contact polishing method with the ML belt was adopted has been developed. It is cheap and can carry out the high-precise and high-efficient re-profiling.
