A comparison of two minimum quantity lubrication delivery systems
Abstract
Purpose
The purpose of this paper is to compare the performance of single- and dual-channel minimum quantity lubrication (MQL) for reaming spool bores in an automotive transmission valve body.
Design/methodology/approach
Machining experiments are conducted under various parameters for both single- and dual-channel MQL. Comparison metrics include part surface temperature, spindle power consumption and hole quality. Experimental data from traditional through-tool flood coolant are provided as a baseline for spindle power consumption and part quality.
Findings
The results show that with proper tooling and machining parameters, dual-channel MQL can perform equivalently or better than flood coolant. Single-channel MQL was not deemed suitable for this machining application.
Practical implications
The results of the study show that MQL can be successfully applied for precision reaming of aluminum and can provide guidance in developing an MQL system.
Originality/value
Few studies have been performed for reaming holes in general, and very few studies have been performed for reaming with MQL. Reaming is a critical operation used to create holes with precise quality. No study was found in the literature review that directly compared the performance of single- and dual-channel MQL delivery systems.
