Abstract
We expected that the addition of fine wood particles in bonding materials of grinding wheels improve the polishing mechanism of surface finishing. In the experiment of finding suitable size and hardness of wood particles to be added to grinding wheels, first of all, we studied the effect of heating time and temperature to the distribution of wood (Western hemlock and Douglas fir) particles prepared to the size of 100 meshes. Experimental results showed that the heating time to the wood particles did not effect to the distribution of particles, and that finer particles were produced by the heating of higher temperature.
