Study on application of lubrication technology in turning pure iron

摘要

In the process of precision turning parts of pure iron, tool wear is very serious. The tool wear has been a key factor to affect the precision of parts. In this paper, the experiments of turning pure iron by use of carbide tools have been carried out in different cooling and lubricating conditions. Based on the analysis of the SEM pictures of carbide tool wear morphology and the compare of the carbide tool wear degree in different cutting conditions, it can be concluded that the carbide tool wear mechanism are mainly adhesion wear and fatigue wear and the benefit of lubricating condition is better than cooling condition to improve the tool life. According to the results, the application of CMQL technology can effectively reduce tool wear in turning pure iron.
