采用单点金刚石修整工具在氧化铝砂轮上切出浅周向槽。然后进行缓进给磨削实验，以比较这些槽轮与非槽轮的性能。结果表明，对于本研究中使用的条件，在工件发生烧伤之前，带槽砂轮可以去除两倍于无槽砂轮的材料。结果还表明，槽轮可以提高磨削效率，降低功耗高达61%。虽然与无槽砂轮相比，使用带槽砂轮导致工件表面粗糙度略有增加，但带槽砂轮能够去除高达37%的材料，同时仍保持工件表面粗糙度值低于0.3μm（“优质”表面光洁度），可多去除120%的材料，同时仍保持工件表面粗糙度值低于1.6μm（“平均质量”表面光洁度）。
A single-point diamond dressing tool was used to cut shallow circumferential groove on aluminum oxide grinding wheels. Creep-feed grinding experiments were then carried out to compare the performance of these grooved wheels with a non-grooved wheel. The results showed that, for the conditions used in this research, a grooved wheel could remove twice as much material as a non-grooved wheel before workpiece burn occurred. The results also showed that a grooved wheel can improve grinding efficiency by reducing the consumed power by up to 61%. Although the use of grooved grinding wheels caused the workpiece surface roughness to increase slightly when compared to a non-grooved wheel, the grooved wheel enabled up to 37% more material to be removed while still maintaining workpiece surface roughness values below 0.3μm (“fine quality” surface finish), and up to 120% more material to be removed while still maintaining workpiece surface roughness values below 1.6μm (“average quality” surface finish).
