The grinding techniques and electro-deposited wheels suitable for a 13% Cr-Ni dental casting alloy were determined. The lever-type grinding test machine modified in the previous study was used to investigate the grinding performance of experimental wheels of CBN- and diamond-particles. Depression of the diamond wheel against the work yielded unfavorable grinding results. Not only depression of the wheel against it but also moving the wheel over it with a heavier pressure is desired for higher grinding efficiency and its durability. Probably, the undurability of this wheel is associated with abrasive attrition due to oxidation or some chemical reaction with the work. The CBN wheel had not been suitable for the Co-Cr alloy tested in the third paper, but it exhibited very excellent performance for grinding of the Ni-Cr alloy, even without being moved over the work. Although being high in cost, the CBN wheel may pay for the very high performance and its durability.
确定了适用于13%Cr-Ni牙科铸造合金的磨削技术和电沉积砂轮。使用在前一项研究中改进的杠杆式磨削试验机来研究立方氮化硼（CBN）颗粒和金刚石颗粒实验砂轮的磨削性能。金刚石砂轮压向工件会产生不利的磨削结果。为了获得更高的磨削效率及其耐用性，不仅需要砂轮压向工件，还需要用更大的压力在工件上移动砂轮。可能，这种砂轮的不耐用与由于氧化或与工件的某种化学反应导致的磨料磨损有关。CBN砂轮不适用于第三篇论文中测试的钴铬合金，但即使不在工件上移动，它在磨削镍铬合金时也表现出非常优异的性能。尽管CBN砂轮成本高昂，但它的高性能和耐用性可能物有所值。
