Outline of Final Research Achievements |
In this study, a high-speed constant pressure grinding device having an in-process dressing mechanism was investigated, and high-speed constant pressure grinding experiments on a polycrystalline diamond (PCD) were carried out, moreover grinding temperatures were analyzed using FEM. In consequence, it was clarified that a grinding efficiency and a surface roughness were improved concurrently with increasing wheel speed. Moreover, an estimated grinding temperature of workpiece surface exceeded 850 degrees C at 100 m/s in wheel speed in dry condition. It was indicated that high-temperature softening of diamond was accelerated. It followed that grinding efficiency of diamond was dramatically increased using the grinding method accelerated by high-temperature softening on PCD.
