仿形打磨机打磨钢轨焊头平直度的注意事项

Matters needing attention for profile grinding machine grinding rail welding head flatness

钢轨焊头平直度是无缝线路铺设的重要控制指标,也是影响铁路旅客舒适度和轮轨作用力的重要因素,主要从钢轨焊头平直度打磨的现状和常用仿形打磨机的性能进行分析研究,总结了仿形打磨机进行钢轨焊头打磨过程中的一些注意事项,为钢轨焊头打磨提供一些建议和思考。

The important control index of the straightness of the rail welding head has been laid on the seamless line, and it is also an important factor affecting the comfort of the railway passenger and the force of the wheel and rail. This paper mainly analyzes the status of the flatness of the rail welding head and the performance of the commonly used model grinding machine, and summarizes the process of the rail welding head grind- ing. Some points for attention are provided for the grinding and welding of rail welding head.
