The idea of sustainability is becoming more defined and better understood. However, most manufacturers still are not taking the necessary steps to implement newer proven technologies that employ the philosophy of sustainability. Generally speaking, manufacturers still associate sustainability with higher costs. However, when we break down the investment and operating expenses of “wet” manufacturing systems we begin to understand just how much they are costing us. One huge step towards sustainability is eliminating the costly consumable known as “coolant“. Minimum Quantity Lubrication (MQL) technology eliminates the large quantity of water and oil based coolants and replaces them with a small quantity of lubricant mixed with air. The air oil stream is precisely metered and delivered to the cutting edge. The philosophy of MQL technology is based on the principle that more isn’t better. Only use the quantity needed for the application, because enough is as good as a feast.
Manufacturers applying MQL are reaping the many sustainable benefits. Their workers are safer. Operators, skilled trades, and engineers are no longer exposed to the toxicity, bacteria, and fungi risks that come with traditional “wet” manufacturing systems. The metal chips produced in MQL applications are nearly dry and much cleaner. The chips are easier to recycle and more valuable as a recycled material.
Materials that are poor thermal conductors generally require cooling power that MQL cannot provide. As such, MAG’s vision for next generation dry machining is to evolve from their significant MQL expertise and replace or supplement MQL with Minimum Quantity Cryogenic (MQC) technology enabling higher cutting speeds and productivity.
