3D Grinding with 4 point measuring system:
It has got the most accurate roll shape measuring for
roundness. The running time of the rolls and the bearings are
extended, roll change intervals are longer and the shut-down times
in the paper machine and maintenance costs are reduced.
The Richter Karhula Oy site in Kotka/Finland looks back on a
long and traditional history.
Founded in 1889 as “Karhula workshop” and in the following
centuries active as part of well-known manufacturers such as
Ahlström, Valmet and Metso. In 2013, Richter acquired the site and
now produces on approx. 20,000 m² for customers from all over the
world, particularly in the area of small to large rolls (up to 80 to.) and
vacuum pump service.
Thanks to the know-how of our employees and our very
well-equipped machinery park, we can support our customers as a
reliable partner in word and deed. Our expertise, especially in the
昀椀eld of special rolls such as de昀氀ection compensated rolls (all kinds
of), suction rolls etc. is well known in the market.Customer service
and satisfaction is always our top priority,
The following example illustrates our approach to this.
A potential customer from Hungary had enormous problems
with a zone-controlled de昀氀ection compensating roll, the only spare
roll was at a competitor’s service center. The problem occurred
during a late shift on Saturday. The customer tried to reach the other
supplier but without success.
They remembered a visit from our sales manager a few
weeks earlier and tried to call him, with success. We immediately
arranged transport with our forwarders and the roll arrived at our
workshop within a few days.
The necessary work was carried out day and night due to
the urgency. After a successful test run, the roll was sent back to the
customer in the best possible time. Customer service is in our DNA
and we are proud to call this customer nowadays a partner who
regularly sends us their rolls for service.
