| Abstract: | The manufacturing of high speed railway need high flatness requirement. Prefabrication adopting the mechanization and standardization operation, positioning of drilling clamping fixture using numerical controlled machine tool preciously, measuring adopting high precision instrument measurement and digital software processing can ensure the drilling precision of the switch board . In view of the deference of the 2 kinds of track switch board, drilling and assembly used in the roadbed and bridge , the construction technology and craft of ballastless track track switch board drilling and related problems are out forward. |
