Sandwichboard panels

The core construction, consisting of a wooden frame with honeycomb core is covered on both sides with plywood, hardboard or particleboard. Each of the three layers have thickness tolerances which, added together, need calibration before further processing.

Panels with solid wood edge materials

Particle or coreboard with solid wood edges calibration prior to pressing the thin veneer layer on the surfaces.

Chipboard panels

In a few countries, raw particleboard panels are already calibrated by the supplier. However, in most countries this is not the case, and, for good finishing results, calibration is necessary.

For these three types of substrate, calibration is a definitive must whether the panels are being veneered or finished immediately. Only with a precisely calibrated workpiece: - A perfect veneer sanding finish can be achieved, - An even finishing material application is guaranteed, - A perfect wood and sealer sanding can be achieved. In addition, the application of only low finishing material quantities permits considerable material savings. The Superfici calibrating machine is often positioned at the head of the veneering line directly in front of the glue spreading machine (see sketch).
