Uni-Max Revolution(TM) Minimum Quantity Lubrication (MQL) system allows users to customize lubricant output volume for each tool in machine directly from CNC program. Developed specifically for OEM installations on CNC mills and turning centers, system can also be retrofitted on machines with available M-code outputs. MQL technology accurately applies small amounts of lubricant, such as UNIST Coolube® 2210, to interface where cutting tool meets material being worked.
