CNC Under Floor Wheel lathe is an automatic machine for simultaneous profiling of new or worn out wheels of railways vehicles in situ. Wheel sets of railways rolling stock i.e. locomotive, coaches, wagons etc. are turned on this machine when in assembled condition. It is equipped with dual CNC tool post for turning any wheel profile along with pre and post measurement system.
Pl. note that improvements is a continuous process. Hence, details explained above may undergo some changes meeting functional, quality and productivity requirements of the required technical specification.
Why you choose us for your next project!
- Extremely rigid dual column construction made from closed-grained castings.
- All four drive rollers of both the machines moves up in synchronized mode with displacement feedback during lifting and centering of wheel set
- CNC based wear measurement system for economical depth of cut.
- Single, centralised control desk to monitor entire wheel measurement & machining
- Quick change tooling for swift operating cycle
