Unist MQL (Minimum Quantity Lubrication System): The Future of Metal Cutting Fluid
Nowadays, ‘going green’ is an important social- and environmental-responsibility consideration for many manufacturers. Implementing a Minimum Quantity Lubrication System (MQL) with Unist Coolube® is an easy step to take towards this direction. The minimum oil system MQL is the process of applying tiny amounts of high-quality lubricant directly to the cutting tool or work piece interface instead of using traditional flood coolants.
MQL minimises your environmental impact by significantly reducing fluid usage and eliminating the need for coolant treatment and disposal. These near-dry machining benefits are multiplied further when using 100% biodegradable Coolube® lubricants which are formulated from renewable plant-based oils. When considering these facts, along with the performance benefits of Coolube® and MQL, it becomes clear that this should be the future of metal cutting fluid.
What Makes Coolube® Unique?
Coolube’s polar molecules have opposing charges at each end. This causes Coolube® molecules to align and create strong bonds.
Using the right lubricant is very important in MQL applications. The perfect lubricant will adhere to the surface of the tool and provide a thin, low friction barrier between the cutting tool and work piece. Studies have shown that Coolube® has superior properties which make it an ideal lubricant.
Coolube® reduces friction 50% better than typical mineral oils, preventing heat build-up and resulting in longer tool life and a superior cut finish.

Unist MQL Application Systems
Coolube® is most effective when accurately applied with a Unist MQL application system. Unist systems feature precise air operated metering pumps that can deliver Coolube® in quantities of less than a drop per cycle. Coolube® is typically mixed with a small amount of compressed air right at the nozzle tip to disperse the fluid and propel it to the cutting tool.
The ability to precisely control both the fluid and air is the key to maximizing productivity when applying Coolube®. Unist manufactures a broad range of metal cutting application systems from basic systems for saws or drill presses to sophisticated electronically controlled systems for CNC machines. All of our systems feature a lifetime warranty on the fluid metering pumps when used exclusively with Coolube® lubricants.
Coolube’s® 100% natural, non-toxic, renewable plant oil-based composition makes it an ideal choice for manufacturers who care about their environmental impact. Coolube® contains no petroleum products, is 100% chlorine and silicone free and produces no harmful VOC’s. Coolube® is completely biodegradable, yet still has a long shelf life.
Impact on Your Shop
Coolube® is as good for your shop as it is for the global environment. Its non-toxic formula is safe for workers and will not cause dermatitis. Implementing MQL with Coolube® also eliminates coolant spills and overspraying, resulting in dry machines and floors and improved safety conditions.
Impact on Your Bottom Line
Coolube® is one of the most cost-effective metal cutting fluids available when you consider the amount of Coolube® that is actually required and the additional benefits it offers. Coolube® is most effective when applied sparingly. In a typical operation, the amount of Coolube® consumed in an is typically only a few millilitres. This is in stark contrast to traditional flood coolant systems that require litres of coolant, coolant filtering, testing, treatment, and toxic disposal. Replacing a flood coolant system with Coolube® and a Unist MQL minimum oil system eliminates these costs while often increasing tool life and improving surface finish. Additional savings include reduced housekeeping and cleaning costs and an increase in the recycling value of chips because they are clean and dry.
