Rafamet UFB 125N Floor wheel lathe

The Rafamet UFB 125 N Above Floor Wheel Lathe is CNC double saddle special purpose lathe designed for reprofiling railway rolling stock wheel sets with axle boxes, gears and brake discs, operating in roll in roll out 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, individually 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
Adjustable track gauge in the range of 1000 to 1676 mm
