Edge Finishing

It is not necessary to apply edging strips to Compact Wood and for many applications clean sawn edges are sufficient. A spindle moulder or router may be used to achieve a superior finish or a profiled edge.

Although it is not possible to achieve complete freedom from cutter marks, they can be minimised by feeding the work at a constant controlled speed using a mechanical power feed.

Care should be taken to avoid pausing during cutting and profiling, as burn marks may result which are difficult to remove. Where it is desirable for edges to be completely free from cutter marks, a further sanding and scraping operation is necessary. Edges may be further enhanced by buffing with steel wool and applying silicone-free oil. Chamfering or profiling the edges of Compact Wood panels will reduce the risk of edge impact damage.

There are various CNC cutters that work well when cutting Compact Wood panels. TCT (Tungsten Carbide Tipped) will give similar results to PCD (Polycrystalline Diamond Tipped) cutters, but with a shorter life span of the cutter.

Before any CNC operations are carried out on Compact Wood, it is important to remove the protective film from the surfaces. The film may decrease the suction power of the CNC bed which could cause the laminate to move while a CNC program is running. The following are recommended feed speeds depending on the expected quality of the cut:

  • 18000 RPM with a speed rate of 1524mm / minute will deliver good quality edges
  • 18000 RPM with a speed rate of 762mm / minute will deliver very high quality edges

Saw blades normally used for cutting double sided composites are generally suitable for cutting Compact Wood®. Saws of less than 2mm in thickness are not recommended. Breakout on the underside of Compact Wood sheets can be avoided by various methods:

  • Using a pre-scoring blade on the underside.
  • Using a base-board of plywood beneath the Compact Wood sheet.
  • Altering the exit angle of the saw blade by adjusting the height setting. The higher the saw blade the better the top cut and the worse the bottom cut and vice versa. The feed speed essentially governs the quality of the saw cut when sawing Compact Wood® having two decorative faces. A speed of between 0.03 mm and 0.05 mm per saw tooth has been found to be the most successful.

Round off corners at cut-outs to avoid stress cracks or cracking. The recommended radius for all internal cut outs is 8-10 mm.
