This lathe is suited for operations including outer diameter turning, surface profiling, tapering, and finish machining. It is capable of handling large diameter rolls with long lengths and high mass. ACE ENG’s roll lathe ensures high dimensional accuracy, concentricity, and surface finish required for demanding rolling applications.

With CNC control, the machine can execute complex tool paths, compensate for tool wear, and maintain precise tolerances over long machining cycles. The lathe supports machining of heavy steel or alloy roll materials. It is part of ACE ENG’s advanced roll processing capabilities, enabling the production and refurbishment of industrial rolling components.
