Trimming unprocessed panels for engineered wood flooring (EWF) in a most exceptional way — that was the task assigned to HOMAG Group Engineering by one of the largest manufacturers of floor coverings in North America.
The special feature:
EWF is found almost exclusively on the North American market. This manufacturer’s EWF consists of three layers: a 6 mm thick HDF core layer, a top layer made from 1.8 mm peeled veneer (oak, hickory, maple or walnut), and a back layer of 1.8 mm peeled veneer.
The finished floor planks have a tongue and groove all around or a click profile.
Because of the different standard formats used for peeled veneer and HDF panels, the unprocessed panels (1510 x 2460 mm) have a large veneer overhang of up to 150 mm. The panels also exhibit significant curving as a result of the hot pressing process. Before the unprocessed panel can be processed further, the veneer overhang must be removed as it would otherwise cause malfunctions during the subsequent stages of processing. However, as little as possible of the HDF core layer should be removed as it is the most expensive part of the panel.
