MQL technology for CNC machines


  • Revolutionary MQL technology

    The Revolution™ is a reliable, digitally-controlled applicator designed specifically for CNC machines. Its patented technology brings accuracy, precision, and repeatability to your cutting tool lubrication. The Revolution™ offers up to two independently-controlled MQL outputs. Each can be programmatically controlled through M-codes. The Revolution™ is a good choice for through-spindle lubrication when digital control is needed but only a few MQL rates are required.

Revolutionary control

The Revolution™ allows the operator to control the amount of fluid being dispensed directly from the CNC program. Support for MQL rates down to 6 mL/hr. makes the Revolution™ an ultra-precise lubrication system. Lubricant is delivered in programmable steps of 25, 50, 75, or 100% of a user selectable maximum rate. In addition to the MQL output, the Revolution™ has an optional air blow-off nozzle to assist in chip removal. This air blow-off delivers electronically adjustable pulses to maximize effectiveness while minimizing the air used. Both the frequency (1-255 pulses/minute) and duty cycle (1-100%) can be set. The Revolution™ is versatile and easy to use. All operational setup and configuration are done through intuitive menus which are shown on a high-contrast 4-line X 20 character LCD display.

Keeping you machining with intelligent, precision application technology

The Revolution™ electronically controls the MQL rates as well as the air blow-off for chip removal. Through-spindle MQL can eliminate the need for external spray nozzles which can get in the way and require positioning. With proper design, fluid passages can be placed to deliver the MQL output precisely where it is needed for each specific tool, eliminating the need for operator adjustments. Active monitoring of flow, pressure and fluid level ensures you know when critical situations arise, so you can react before you destroy valuable tools or ruin your work piece.
