For decades, industrial manufacturers have used flood coolants to help lubricate machines and tools while machining and metal working. The heat produced during the metal on metal cutting process can reach temperatures high enough to degrade or even destroy the cutting piece and the tools used during that machining process. So, using flood coolants to reduce this heat has been the most common method used for some time. While it does provide some heat reduction by quenching, it has many downsides.
Micro lubricants use only microscopic amounts of the lubricant, which is applied in the exact spot needed during the cutting, or machining process. Because of the chemical composition of the lubricant, it forms a thin coating on the cutting tool and work piece. If the lubricant is formulated properly, like the micro lubricants developed by Maglube, it can provide up to 300 times the lubricity of some flood coolant fluids. This is due to the chemical make up of the lubricant.
With the introduction of MQL or micro lubrication, we’ve eliminated a potentially eco-unfriendly part of the process. Because minimum quantity lubrication uses such a small amount of fluids, there’s no need for cleanup after a production run. Contrast that to a production run using petroleum-based flood coolants and you’ll quickly understand why micro lubrication is far more ecologically acceptable in today’s manufacturing process.
With up to 99.9% of the lubricant being used or burnt up during the cutting process, there’s nothing remaining that needs to be disposed. That’s just not the case with the fluids used in flood cooling. These chemicals have the need to be disposed properly. But many facilities don’t do this. They simply hose down their machines after production, allowing those eco-unfriendly wastes to be washed down the drain, eventually making it back into the environment.
