摘　　要： 针对磨削液的使用性能 ,按四球试验法、攻丝扭矩模拟评定试验法、磨削加工试验法对三种磨削液进行了性能试验研究。结果表明 ,四球试验法的结果重复性较好 ,但该方法以滑动摩擦接触面的油膜强度来评价磨削液的性能 ,与磨削加工试验的结果有较大差别。攻丝扭矩模拟评定试验方法为真正的切削试验 ,与切削加工的相关性较强。磨削加工试验是最能体现磨削液性能的试验方法 ,因影响因素较多 ,需要建立完善的试验装置和试验方法。 Three test methods for grinding performance evaluation of grinding fluids were used to investigate the influences of three kinds of grinding fluids on grinding process. The three test methods are four balls test, tapping torque test and real grinding test. The results show that the four balls test mechanism is based on the oil film load capacity between sliding contact surface. The test results have good repeatability, but there is a large divagation with real grinding test results. The tapping torque test is a real cutting test, it has a good relativity with cutting process. The real grinding test is the best test method for grinding performance evaluation, but there are so many influencing factors on this test method. Therefore, it is imperative to establish canonical test equipment and test method for real grinding test.
