针对钢基体砂轮质量大、在高速超高速磨削中功率消耗大的问题,从启动功率、空耗功率、磨削功率等几方面,测量并分析了碳纤维增强树脂基复合材料(carbon fiber reinforced polymer,CFRP)基体砂轮与钢基体砂轮功率消耗的情况。试验结果表明:与钢基体砂轮相比,CFRP砂轮的质量轻,能够有效减小砂轮在高速超高速磨削中的启动功率、空耗功率以及磨削功率;验证了CFRP砂轮在高速超高速磨削中减轻主轴负荷、减少能源消耗的优越性能。
In high speed and ultra-high speed grinding,power consumption of steel substrate grinding wheel with large mass is high.Aimed at this problem,the power consumption situation,which consisted of starting power,depletion power and grinding power,of CFRP substrate grinding wheel and steel substrate grinding wheel was measured and analyzed.The results indicated that compared with steel substrate grinding wheel,the lighter CFRP grinding wheel could effectively reduce power consumption of the spindle.Also,the superior performances of CFRP grinding wheel in reducing the spindle load and energy consumption were verified.
