The CNC Under Floor Wheel Lathe is an advanced, fully automatic machine designed for simultaneous profiling of both new and worn-out railway vehicle wheels in situ. This versatile machine allows for the turning of wheel sets, including those of locomotives, coaches, wagons, and other rolling stock, while they remain in their assembled condition. Equipped with dual CNC tool posts, it ensures precise turning of any wheel profile. Additionally, the lathe features a pre- and post-measurement system, ensuring accuracy and efficiency throughout the process.

This system enhances maintenance efficiency and minimizes downtime, making it an ideal solution for railway wheelset management.

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.
