FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for rail head finishing and surface hardening. Proposed device comprises the frame arranged to displace along rail head and machining tools arranged on the frame both sides to run in opposite directions and to be fed to rail head rolling surface. Machining tools are composed of two surface cutters engaged via feeder box with common drive. Said cutters are fitted so that their axes of revolution are located in one plane to overlap cutting areas in rail head lengthwise direction.
EFFECT: higher machining speed, lower heating of rail head.
