The UNIST Infinity™ is a Minimum Quantity Lubrication (MQL) system designed to deliver lubricant through the spindle of CNC machines. It provides direct, digital control of air and fluid flow rates, allowing for a nearly unlimited number of air/fluid combinations to meet the needs of different machining operations.
The Infinity™ delivers continuous fluid flow rates from 5 to 500 mL/hr per output. It is not sensitive to fluid viscosity or temperature, eliminating the need for output calibration. This technology also simplifies the overall system by eliminating fluid heaters and complex valves often associated with other approaches.
The Infinity™ provides precise control of lubricant application during CNC machining operations. Its technology simplifies system operation by eliminating fluid heaters and complex valves often associated with other lubrication methods.
Active monitoring of spindle backpressure, fluid flow rates, reservoir levels, and other important operating parameters ensures optimal system performance. If an issue occurs, detailed monitoring of system behavior allows for quick and accurate troubleshooting. The Infinity™ can be integrated into the machine controller for complete and intuitive control from the operator interface. An optional touchscreen interface is also available.





CNC Mill

Active process monitoring ensures optimal performance and an alarm history log makes troubleshooting simple

Directly set the output flow rates. Nearly unlimited MQL output settings provide precise control to optimize your operation

The patent-pending continuous-flow pump delivers accuracy and repeatability, even at very low flow rates

The volumetric nature of the Infinity’s pump technology makes it inherently accurate and repeatable at all output levels for all fluids in all environmental conditions

The Infinity’s™ positive-displacement pump technology results in a much simpler system than those based on other technologies. This reduction in complexity has a direct relationship to the reliability and maintainability of the system.
The elimination of fluid heaters and complex valves that are required for a time-based flow MQL system means there are fewer parts to maintain. Furthermore, the elimination of output calibration saves not only the time and effort, but an entire class of errors related to a bad calibration.

A robust set of control parameters are available in the Infinity™ controller which allows a full and complete integration with the machine controller and access to all of the advanced capabilities of the Infinity™.
A compatibility interface for controllers that may already have interfaces for other MQL applicators is also supported. This compatibility interface gives basic control of the unit with minimal integration effort.
