We specialize in Grinding Calendar Rolls on precision German Roll Grinding Machines, to very close geometric tolerance, resulting in tight control of gauge variation of paper.
Geometric tolerances are:
1) Concentricity : 3 Micron ( depends on Roller construction)
2) Cylindricity : 3 Micron ( depends on Roller construction)
3) Taper : 2 - 3 Micron ( depends on Roller construction)
4) Camber profile : 2 – 3 Micron station to station variation.
Our grinding capacity :
• 1850mm dia X 6500 mm Lg
• 900mm dia X 10000 mm Lg
• 25 tons weight capacity
With an infrastructure of 3 Roll Grinding machines and 5 Cylindrical Grinding machines, we can
We can grind Calendar Rolls, Work Rolls, Back Up Rolls, Dryer Cylinder, Rams, Calendar Rolls for PVC, Granite Rolls, Rubber Rolls etc.
