Rafamet UDA 125 Portal wheel lathe

The Rafamet UDA 125 N Portal Wheel Lathe is CNC double saddle special purpose lathe designed for reprofiling of wheels and discs used in rail vehicles. The machine tool is provided with either radial or axial wheelset clamping system and it ensures machining of solid monoblock wheels and wheels with tyres of both used and new wheelsets. Machine main structure made in form of portal as extremely rigid, heavily ribbed box type, high grade grey iron casting providing maximum vibration damping capabilities during cutting process
Main drive powered by two AC motors of continuously variable rotation rates providing high productivity and quality of wheelset machining
Automatic and reliable profile wear measurement using touch type measuring heads
Versatile equipment and wide programming options guarantee precise machining of even unusual wheel profiles
Multi track gauge version available
Two versions of wheelset clamping system
Roll through and or Roll in Roll out arrangement
Available Machining
