Study on Service Performance Evaluation of Grinding Coolants

Abstract

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.

A comprehensive review on the grinding process: Advancements, applications and challenges

“…The selection of proper coolant is not the only way to avoid thermal damage as the grinding has a larger contact area. Ge et al 77 studied various grinding coolant's performance with three different coolant application methods. These methods include the tapping torque test, real grinding test and four-ball test.…”
