Wheel profile measurement

Non contact wheel profile measuring presents the possibility of fast, non-contact registration of the parameters for subsequent wheel-set machining. For this profile registration a laser sensor is being moved along the profile.

By simultaneous scanning of the travel path and the laser distance values, the profile is registered by the computer, and then the characteristical parameters as, for example, thickness, height and width of the wheel flange, and wheel width will be determined. The systems, which are also in operation in the tramway- and underground sectors, have been developed in co-operation with Deutsche Bahn AG and have been integrated directly in wheel-set processing machines; so that the processes of pre-measuring, machining, and control-measuring can be carried out by one machine.
