    Options & Accessories

    Unist Spindle Kit
    Unist Spindle Kit
    To get the best through-spindle MQL performance, it is necessary to deliver the lubricant and air in separate channels through the spindle to the tool holder. The Unist Spindle Kit includes two specially-designed components: a rotary union and a fluid delivery tube.

    Unist Tool Holder Kit
    Unist Tool Holder Kit
    Unist MQL Tool Holder Kits fit into most common CAT and BT style tool holders. The MQL optimized retention knob and MQL tool holder insert ensure proper aerosol delivery from the end of the spindle to the shank of the tool.

    Unparalleled Precision

    The Infinity uses patent-pending pump technology to deliver fluid accurately and repeatably, even at very low flow rates. It delivers continuous flow rates from 5-500 mL/hour, is not sensitive to fluid viscosity or temperature, and eliminates the need for output calibration. This technology simplifies the overall system, eliminating fluid heaters and complex valves often associated with other approaches.

    The Infinity gives you direct, digital control of air and fluid flow rates. This provides a nearly unlimited number of air/fluid combinations for use in any operation. The Infinity’s precision and accuracy make process control simple and effective, and its reliability makes it a shop favorite.

    Active monitoring of spindle back pressure, fluid flow rates, fluid tank levels, and other important operational parameters ensure the system is performing well. In the rare case that an issue does arise, detailed tracking of the system behaviors make troubleshooting fast and precise.

    The Infinity can be integrated with the machine controller to give complete and seamless control from the operator interface or an optional touch screen interface is available to give operators an easy and intuitive interface at the unit itself.

    Less is more

    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.

    Easy Integration

    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.
