Thru-the-tool lubrication system

Unist, Inc. has released its Tornado Thru-the-Tool Lubrication System, which can be retrofitted to CNC and other coolant-fed drilling applications. The newly configured system connects directly to a machine equipped with coolant inducers. The system includes a solenoid valve that allows the fluid delivery signal to be wired directly to the CNC drilling machine. It also has a quick disconnect coaxial air/fluid line for easy connection to the inlet port on the machine. The unit can be connected to shop air, or an independent air supply.
The Tornado Micro-Fluidization System is a positive displacement system that produces a total range in fluid output of 1 drop to 100 drops per minute (0.03 cc to 3.3 cc per minute). Unist says that using its low air pressure drop technology, gives the Tornado System nearly unrestricted airflow and minimum air pressure drop to the cutting tool edge. That allows the system to maintain a consistent, precise flow of lubricant throughout the cut. The company says this feature results in improved hole quality, improved chip evacuation and increased production rates.
The Tornado System is designed for use with high efficiency lubricants, such as Unist’s Coolube line of vegetable based lubricants. When it is used with Unist Coolube products, the company says the Tornado System permits the user to drill at faster speeds and use increased feed rates while eliminating housekeeping requirements associated with flood cooling. Unist also manufactures a system it calls Power Cool for the similar applications in which water based fluids are required.
