The CorruGrind is used for producing corrugated rollers for manufacturing corrugated cardboard. Modern systems for corrugated cardboard operate with a paper run-through speed of up to 700 m/min. This places the most demanding requirements on the production accuracy of the corrugated rollers.
If the paper were to run through the system at such a high speed, even the smallest deviations in the pitch of the toothing profile or concentricity errors of the corrugated roller would result in the paper tearing.
From the standpoint of production and due to the high accuracy involved, a corrugated roller can be compared to a precision gearwheel, however with a toothing profile with a length of 2,000 to 3,000 mm.
