calendering process, precision rolls are used in order to
guarantee that the final product has optimum properties. The
rolls used for these purposes must meet extremely high
standards. Calender rolls of maximum precision with respect
to geometry, runout and surface finish are supplied for use
in your continuous duty application. They are designed and produced in close cooperation with the end user. Structural and thermal stresses are controlled by roll design and manufacturing experience.
rolls are manufactured to comply exactly with customers'
specifications. They are designed and produced in close
cooperation with the end user. Structural and thermal
stresses are controlled by roll design and manufacturing
are fully inspected. Each manufacturing step is documented,
because complete quality assurance is a matter of course.
Research and development are considered as means of constant
improvement of materials, processes and service.
offer rolls made from various materials:
cast iron (single poured)
cast iron with nodular cast iron core (compound casting)
chrome-alloy special cast iron
rolls are manufactured using modern CNC machines at all
manufacturing stages, maximum precision is guaranteed with
respect to cylindricity, roundness, concentricity and surface
quality. Besides cylindrical barrel grinding all types of
crowns, as well as special roll profiles, are possible. Rolls
can be furnished with a matt, engraved or corrugated finish.
oil or water heating systems, roll grinding temperatures of
up to 300 -C can be achieved. This ensures maximum precision
for the roll when it is heated up to operation temperature.
Our expertise, which is the result of continuous research and
development in the field of superfinishing, even allows us to
produce rolls with a flawless mirror finish.
