Tungsten Carbide Cutting Tool Wear Rate Relating to Synthetic Wood Products Cutting

It is known that, during the synthetic wood products’(such as particle board) cutting processes, the factors like board density, resins and glues as well as silicon dioxide particles, which would affect tool wear, needed to take into consideration when adopting tungsten carbide cutting tool.



The function of silicon dioxide sand is normally referred to smooth the surfaces of the particleboard and since a large amount of the powder is usually ground against the wood surface, some of the particles may become embedded in the surface which subsequently may cause increasing the tungsten carbide cutting tools’ wear rates. The effect of silicon dioxide particles was investigated by Huber Wear, It is found that the wear rate increased linearly with increasing silica particle content. Tool wear was shown to be more closely related to the quartz content of wood than to the total salicaceous residue content.
