This paper deals with the grinding characteristics of newly developed ultrafine-crystalline cBN (cBN-U) abrasive grains in creep feed profile grinding of high-speed steels. Experiments for producing a V-shaped groove on a flat surface in one pass by creep feed grinding have been carried out using new polycrystalline cBN-U and representative conventional cBN (cBN-B) abrasive grains. When grinding with the cBN-U wheel, both radial wear and profile wear are less, and hence the grinding ratio is around 4 times higher than that with conventional cBN-B wheel. Grinding force in grinding with the cBN-U wheel is reduced by 5∼15 % compared with that in grinding with the cBN-B wheel. The cBN-U abrasive grain is suitable for application with a high dimensional accuracy in creep feed profile grinding for high-speed steel, because it gives less profile wear, and hence better form retention of the wheel, than conventional cBN abrasive grain. |
