Measurement of the radial runout of a cutter disk

During the manufacture of veneer strips from laminated wood, the precision of the cutting disk determines the quality of the final product. High demands are placed on the veneer strips in terms of dimensional conformance. The thickness of the strips must be less than 1 mm and may only have tolerances in the micrometer range.

In order to comply with the quality criteria, the radial deviation of the cutting disk is measured and monitored during the production process using a non-contact optoNCDT 2300 laser triangulation sensor. This means that high demands are placed on the measuring system: Dust, chippings and a shiny target surface must not affect the measurement accuracy. The cutting disk has a diameter of 3200 mm and is equipped with 24 knives. The rotation speed is 180 to 210 rpm.
