 note = {In this study, total twelve kinds of cemented carbide bits for machine boring. that is, type K bits. impact-resisting bits and micro-grained bits were prepared. And tool-life tests whose final number of boring holes of each bit was 1000 in the machine boring of particleboard and MDF (medium density fiberboard) were performed under boring conditions of 3000rpm of spindle speed, O.1mm/rev of feed per revolution and 30mm of boring depth, the progression of spur edge recession of each bit was examined. From the experimental results, the relationship of edge recessions for five kinds of type K bits (K01-K40) to edge hardeness or cobalt content was not clear. For five kinds of impact-resisting bite (V4-V6 and E1), V6 bit showed the highest edge recession and these edge recessions progressed slower as the edge hardness became higher. For two kinds of micro-grained bits(F), edge recessions showed extremely small as compared with those of type K bits and impact-resisting bits. Furthermore, it became clear that edge recessions for twelve kinds of cemented carbide bits had good correlations with edge hardness and grain diameter of tungusten carbide., 論文},
