Carbon-based layers for mechanical machining of wood-based materials

In the machining processes of wood-based materials, especially those of laminated chipboards, one of the most important features is the durability of the machining tool. This work presents the results of an investigation on the properties of sintered carbide tools modified using carbon and composite (carbon- and titanium-based) layers. The machining edges were examined before and after the modification processes. Coatings were applied under operating conditions using the spindle molder. As a result of the investigation, blunt characteristics as a function of the amount of machined material as well as characteristic wear profiles registered after the tests are described. The usefulness of each modification process was specified based on wear resistance criteria. Obtained investigation results prove the possibility to apply carbon-based coatings in mechanical machining of wood-based materials, in particular, in the treatment of non-laminated chipboards.
