Precision Regrinding of Existing Rolls for IRM Model 2050 2-High Laboratory Rolling Mill

Description

This service includes the precision regrinding of the customer's existing work rolls for the IRM Model 2050 2-High Laboratory Rolling Mill. The rolls will be restored to provide accurate rolling performance for continued production of strip and sheet in research and process-development applications.

Rather than grinding between centers, our process references the roll journals themselves, ensuring the roll body remains concentric with the bearing journals that ultimately determine running accuracy in the mill.

Grinding between centers can introduce errors if the center holes have experienced wear or were not originally machined perfectly concentric to the journals. By grinding directly from the journals, we restore the working surface using the same reference as the roll bearings, producing finished rolls with less than 0.0002" Total Indicated Runout (TIR) from journal to journal.

Both rolls are precision ground to matched diameters, ensuring they share the same working diameter for proper rolling geometry, uniform pressure distribution, and accurate strip thickness. This minimizes roll mismatch and helps maintain consistent rolling performance throughout the service life of the roll set.

Following grinding, each roll receives a fine satin finish to restore the surface required for precision laboratory rolling. The finished rolls are then inspected to verify dimensional accuracy, runout, and overall serviceability prior to shipment.
