中文摘要：
主要对纳米粒子射流微量润滑磨削性能进行实验评价。采用K-P36数控平面磨床,选取干磨削、浇注式磨削、微量润滑磨削和纳米粒子射流微量润滑磨削4种工况条件,分别从磨削力、磨削G比率、磨削温度和表面粗糙度方面进行磨削性能评价,结果表明:纳米粒子射流微量润滑磨削改善了换热能力,与干磨削相比降低了将近150℃,干磨削得到的工件表面粗糙度Ra值为1.2μm,纳米粒子射流微量润滑磨削Ra值为0.58μm,工件表面质量显著提高;在纳米粒子的润滑作用下,得到的磨削力较稳定,且比干磨削和微量润滑磨削得到的磨削力减小15%以上;纳米粒子射流微量润滑磨削G比率在4种工况中最高,值为33,干磨削仅为12,比其他工况增大约一倍,砂轮的磨损明显减小,延长砂轮使用寿命。
