诺顿产品提高了辊磨效率

两种类型的轮毂都采用玻璃结合结构，导致自由切割磨削。这最大限度地提高了金属去除率，同时从机床提取低功率和产生最小的热量，从而避免冶金损伤。测试是在圣戈班磨具公司的研究和开发中心进行的，使用直径915毫米、宽76毫米的量子轮在一台80千瓦的磨床上进行的。它加工了四种不同的工作辊和备用辊材料- ICDP(不确定冷双浇)铸铁，高铬铸铁，CPC(连续浇铸覆层工艺)高速钢，和(HSS)标准高速钢-所有热轧轧机。表面光洁度达到了半微米到一微米之间。圣戈班说，ICDP的结果令人震惊。与次之的陶瓷砂轮相比，Quantum的研磨比(G比)高出60%，G比是每克砂轮消耗的金属去除量的克数。与最差的轮子相比，Quantum的性能是140%。在加工CPC高速钢轧辊时，圣戈班磨具产品的G比比比所有其他陶瓷颗粒轮的基准要好60%左右。铬铁和高速钢轧辊磨削显示一个较小的，但仍然明显增加车轮寿命。 Across all the trials, the manufacturer claims an average increase in wheel life of 35%. Another test showed a rise in metal removal rate using Quantum of over 60% - from a Q of 2.3 up to 3.7 mm3/s/mm - while the power drawn from the grinder was 20% less. Vortex aluminium oxide grinding wheels have also proved effective at processing most rolls, but not work rolls, as used in hot rolling mills. The abrasive wheels cost less than Quantum and offer a proportionately lower G ratio. Nevertheless, Vortex performance in roll grinding is still very high, it is claimed.
