Rafamet UFD 140N portal wheel lathe

The UFD 140 N Portal Wheel Lathe is CNC double saddle special purpose lathe designed for reprofiling of railway rolling stock wheelsets with axle boxes, gears and brake discs, operating in roll through system. Machine major body elements made as extremely rigid, heavily ribbed box type, high grade grey iron castings providing maximum vibration damping capabilities during cutting process

Main drive from six independent friction rollers, powered by AC motors of continuously variable rotation rates providing high productivity and quality of wheelset machining
Automatic and reliable profile wear measurement using touch type or laser based system
Versatile equipment and wide programming options guarantee precise machining of even unusual wheel profiles
Multi track gauge version available
Roll through and or Roll in Roll out arrangement
