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 6500mm Lg
• 1320mm dia X 10000mm Lg
• 25 tons weight capacity
We can also carry out repair of broken journal/side shaft or Calender Rolls.
With an Infrastructure of 3 Roll Grinding and 5 Cylindrical Grinding Machines, we can meet very short delivery times to minimize your shut down time.
