MQL minimizes a shop’s environmental impact by significantly reducing fluid usage and eliminating the need for coolant treatment and disposal.

 

In a recent e-newsletter, Unist, designer and manufacturer of industrial fluid application systems, cited a study about micromilling 316L stainless steel using Minimum Quantity Lubrication. (MQL is the process of applying minute amounts of lubricant directly to the cutting tool/work piece interface instead of using traditional flood coolants.) The study found that a properly configured MQL process can reduce the built-up edge on a micro cutting tool and increase tool life as much as 100 times compared to dry milling. It cites the importance of quantifying tool runout, wetting both the cutting tool and the workpiece, and properly positioning the MQL stream to maximize lubrication at the chip/material interface.

 

The report (“Micromilling in Minimum Quantity Lubrication” found in Machining Science and Technology: An International Journal) is available for purchase here. Additional information about the advantages of machining with MQL can be found at Unist’s website as well as this blog post and this article about Ford’s use of MQL.

  • The Case For Supplementary Fire Suppression

    Systems designed to put out fires inside machine tools can provide a level of protection that external systems such as overhead sprinklers cannot. They cost a small percentage of the investment represented by today’s CNC machines and certainly far less than repairing major damage caused by a fire. 

  • A Separator Solves The Tramp Oil Problem

    With their strong attention to routine housekeeping, it's not surprising that this shop carefully researched all methods for removing tramp oil from coolant in machine sumps. If tramp oil is allowed to build up in the coolant, the resulting shop odor, smoke generation and unpleasant conditions for the operators will quickly undermine all efforts to keep a clean shop and maintain an optimum working environment.
