Precise roll grinding with 3D roll shape measurement

Grinding the roll on its own bearings. In addition to providing a smooth surface, roll grinding permits smooth roll rotation in paper machines. If you grind the roll on its own bearings, the rotation and the shape of the surface is a mirror image of the irregularity of the bearings. While it is normally much faster and easier to grind the roll on its own bearings, it requires a tool to compensate for these irregularities. This tool is proper 3D measurement of the roll

Numerical and Experimental Approach for Roll Grinding Process

In paper machine industry, a roll grinding machine is used to finish or maintain roll surface. Excellent surface finish should be homogenous one with silky sheen, free of scratches and any other blemishes. Precision roll provides more efficient roll operation and
