Minimum quantity lubrication (MQL) is used more in Europe than here in the States due to stricter environmental regulations across the pond. However, MQL has a proven track record in working just as well as, or better than, traditional flood coolants for certain applications. Plus, shops don’t have to deal with negative consequences like health hazards, disposal costs and pricey circulation equipment. If you’re interested in learning more about MQL, consider signing up to receive the “MQL Handbook” offered by Unist, the Grand Rapids, Michigan manufacturer of MQL systems for metalworking applications.

The handbook explains how MQL differs from conventional coolant methods, how it works, what equipment is needed, how to develop an MQL process and what fluids work best for it. Sign up to receive the handbook here.


  • Running Unattended at Night Lets Machine Shop Serve New Customers During Day

    Precision Tool Technologies found capacity for diversification not by adding machines, people or space, but by freeing up time. Running unattended—running so it can machine through all 168 hours in the week—has enabled this shop to use hours when staff is present to deliver work that lands outside its established specialty. To achieve unattended machining, some of the biggest challenges have related to basic details such as chips and coolant.

  • 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.

  • Long-Lasting Coolant Reduces Costs, Downtime

    This shop provides a case in point of the substantial savings that can be realized with the proper coolant formulation. Rustlick Ultracut Pro, available from ITW Rocol North America, lasted twice as long in the sump than the shop’s previous coolant, leading to significant operating and maintenance cost savings.
