ThroughSpindle™ MQL Systems
Unist offers the most technologically-advanced integrated lubrication systems
for through-spindle MQL applications:
The Infinity™ sets a new standard for performance in dual-channel, through-spindle, Minimum Quantity Lubrication (MQL) systems. Specifically designed for high-production through-spindle operations, it consistently, reliably, and accurately delivers MQL fluids through the spindle over a wide range of flow rates.
The Infinity™ has unlimited MQL rates and integrates with the machine controller at the PLC level. It’s continuous-flow pump is ideal for critical production cycles with repeated, short-duration operations. Using precise flow measurement, it monitors the pump output in real time down to flow rates as low as 1 mL/hr.
The Quantum™ is a reliable, digitally-controlled applicator suitable for through-spindle applications, complex external-spray applications, or a combination of both. It supports up to six outputs, and its intermittent positive-displacement pumps assure high accuracy with the nearly unlimited MQL rates. Discrete inputs or serial commands allow close integration with CNC programs.
The Revolution™ is designed specifically for CNC machines. Its patented technology brings the same level of computer controlled accuracy, precision, and repeatability to your cutting tool lubrication as the CNC controls bring to your machining operations.
The Revolution™ is a reliable, digitally-controlled applicator with support for up to 2 outputs. It features 4 MQL output settings, each at 25% interval of a user-defined max. The Revolution™ controls its intermittent positive-displacement pumps through M-codes, and is appropriate for applications with a limited set of tool sizes/lengths.
