摘要

Rail re-profiling machine machines longitudinal and cross profile of railway track rails and has rotary frame (2), driver positions (3,4), work cabin (5), drive group (6) and suction device (7). Under the machine frame are the measurement wagon (8), the milling wagon (9) for machining the train travel surface and the milling wagon (10) for machining the inner and outer radii of the rails together with the grinding wagon, which are connected with the tractive device (12) and hydraulic cylinders with the rail re-proofing machine. The production of a trouble-free longitudinal profile per extent of rail, the measurement device on the measurement wagon is controlled, as is the milling head in the milling wagon in relation to the length and depth of the track, so that the rails of the longitudinal profile are milled. The two milling heads in the milling wagons produce fourteen facets on the rail head with a relatively rough surface, which are finely ground by the profile grinding units on the grinding wagon.
