Study on Service Performance Evaluation of Grinding Coolants

摘要

Grinding coolants have the functions of cooling, lubrication, cleaning and rust prevention in grinding process. To avoid the environment pollution, we should develop environmental protection grinding coolants. So it is important to research the performance evaluation for grinding coolants. In this paper, three different test methods for grinding performance evaluation of grinding coolants are used to investigate the influence of three coolants on grinding process. The three test methods are four balls test, tapping torque test and real grinding test. The test results showed that the mechanism of four balls test is simple, and the test results have good repeatability, but there is a large divagation with real grinding test results. The tapping torque test has a good relativity with cutting process. The real grinding test is the best test method for grinding performance evaluation.
