Application of surfaced cutters for machining of wood-based materials
The present paper describes results of recent research aimed to make high wear resistance cutter for machining of wood-based materials. Medium density fibreboard (MDF) was chosen for wear test because it is quite abrasive, ease blunts edges of cutters, is inhomogeneous material: contains glue and different mineral particles. It is well known that cutting particleboard results wearing out of cutter faster than machining of natural wood. Because of this, experimental cutters made by surfacing using submerged arc welding (SAW) technique and prepared material powder mixture spread on the surface of cutters blank, were introduced in this research. Suggested material powder mixture ensured obtaining the high alloyed and wear resistant surface layer on the cutting edge of cutter. The wear performance of experimental and commercial cutter was accomplished on the typical industrial thickness planer with a face milling cutterhead using MDF as workpiece. Wear of experimental cutters showed very similar performance as commercial cutter made of high speed steel HSS18.
