Calender rolls

are used for producing plastic films and rubber sheeting. Even the smallest defects in the roll surface, e.g. pores or cracks, have to be excluded to ensure the best possible quality of the product.


The more precise the grinding of the calender rolls, the lower the product tolerances.
