3.Machining and processing HPL
The cut edges of HPL-Compact can be machined. A machining allowance of 2 – 5 mm is recommended for good edge quality. For large batches, the use of special router heads which were developed for HPL-Compact has proven successful. For profile milling, we recommend the use of diamond tipped tools. Due to the high cutting pressure, secure guiding of workpiece and tool is imperative.
A special edge protection such as coating or painting is generally not required for HPL-Compact. A variety of design options are available for edges which are to remain visible:
1 Straight edge | 2 Rabetted edge | 3 Chamfered edge | 4 Bevelled edge | 5 and 6 Profiled edges
Marks from the blade impact of the profile routers on the routed surface are inevitable. They can be reduced through climb cuts (only with mechanical guiding!). They can be removed during the subsequent profile finish through sanding and then polishing.
To further improve the appearance of the routed edge, we recommend treating the edge with silicone-free furniture oils after machining.
