The Uni-Max® Pro from UNIST is a highly configurable minimum quantity lubrication (MQL) system designed for machining processes requiring multiple lubrication points, advanced actuation, or fluid output monitoring.
With support for 1 to 12 nozzles, the Uni-Max® Pro allows pumps to be controlled individually, in groups, or remotely to deliver a precise, repeatable amount of lubricant exactly where and when it is required. This provides the flexibility needed to integrate lubrication throughout a complex process
Minimum Quantity Lubrication replaces conventional flood coolant with a very small, precisely controlled amount of high-quality lubricant applied directly at the interface between the cutting tool and workpiece.
Rather than cooling the process after heat has been generated, MQL reduces friction at the cutting edge and minimizes heat generation. This significantly reduces fluid consumption while maintaining excellent machining performance.
The Uni-Max® Pro takes this approach further with a modular architecture designed for more complex processes. Each actuation signal can control an individual pump or group of pumps, allowing a single system to manage lubrication for multiple operations or application points.
Configure 1 to 12 outputs, choose fixed or adjustable output pumps, and add fluid output monitoring according to the requirements of your application.
Pumps can be actuated individually or grouped to lubricate different points at different stages of the process. Direct, remote, and common actuation options allow the system to integrate with more complex equipment.
Pumps are tested to 12 million cycles, are self-priming, and are designed for easy maintenance. A fluid shut-off valve also allows pumps to be replaced without lubricant leakage.
Every process has different lubrication requirements. The number of points requiring lubrication, the amount of lubricant needed, application frequency, and how different operations are actuated can vary considerably from one machine to another.
The Uni-Max® Pro is designed around this reality. Its modular architecture allows different pumps, nozzles, actuation methods, and monitoring options to be combined to create a system tailored to the process rather than forcing the process to fit the system.
A single system can supply up to 12 nozzles. Pumps can be controlled individually or in groups, allowing different outputs to be actuated according to the requirements of each stage of the process.
Positive-displacement pumps with 20, 40, or 60 µL outputs, available in fixed or adjustable configurations, allow lubricant delivery to be tailored to different application points.
Optional flow sensors allow lubricant delivery to be monitored, adding an extra level of process monitoring for applications where confirmation of fluid output is important.
The Uni-Max® Pro can be configured for either continuous spray or shot spray operation, depending on process requirements.
In continuous mode, the pumps provide a steady supply of lubricant while the system is operating. The amount applied can be adjusted by changing pump stroke and cycling frequency.
This configuration is particularly well suited to continuous operations such as:
In shot mode, the pumps deliver a controlled amount of lubricant in response to an actuation signal. The number of shots and quantity delivered can therefore be tailored to the operation.
This configuration is particularly well suited to intermittent operations such as:

Adjustable or fixed 20μL, 40μL, or 60μL pumps deliver consistent output, with adjustable stroke and air volume control

Push-to-connect tubing simplifies the installation, replacement, and repositioning of lubrication nozzles.

For hassle-free start-up, pumps draw fluid even if air is present

The fluid shut-off valve allows the fluid supply to be isolated for leak-free pump replacement, simplifying routine maintenance.
With its extensive configuration options, the Uni-Max® Pro is suitable for a wide range of machining operations and automated processes.
Machining cells combining several processes may require lubrication at different locations and at different times. The Uni-Max® Pro can supply these points from a single system integrated with the machine’s actuation signals. For example, a single system can be configured to supply multiple spindles, a drill, and saw blades independently, allowing the lubrication requirements of an entire automated cell to be managed from one system.
In robotic machining applications, entering a cell may require a complete lockout/tagout procedure. Remote pump control allows lubrication to be adjusted without requiring access to the cell.
Positive-displacement pumps provide precise, consistent lubricant delivery even through long tubing runs, making the system particularly well suited to tooling mounted at the end of a robotic arm.
The modular design of the Uni-Max® Pro also makes it an attractive solution for machine builders and OEMs looking to integrate MQL directly into their equipment.
The Uni-Max® Pro can also be configured for a wide range of operations, including:

**** Required timing may vary depending on system configuration.
Lubrication requirements vary depending on the machine, materials, tooling, and different stages of the process. The number of outputs, pump output, spray mode, nozzles, actuation method, and monitoring requirements should therefore all be considered when configuring the system.
Thanks to its modular architecture, the Uni-Max® Pro can be configured to lubricate a single point or manage multiple operations from one system.
