Aerosol-Booster AB 250 LC
Minimum lubrication system for internal feed with programmable dosing
- for machining centers and special machines with one to six spindles
- external control of operating pressure, total volume flow and aerosol content for programmable, tool-dependent lubrication
- highest flexibility
Operating principle
The Aerosol Booster generates an air-liquid mixture with extremely small liquid particles from non-water-miscible lubricants. This aerosol is suitable to be conducted over longer distances in hoses as well as through rotating spindles and tools. The cooling channels of the tools cause a nozzle effect through which the incoming aerosol condenses, i.e. oil and air are separated. This results in precise oil lubrication at the tool.
Three different aerosol generators are installed in the AB 250 LC, which can be controlled externally by solenoid valves individually or in groups. This enables programmable, tool-dependent lubrication.
Advantages
- wear-free and reliable, no moving parts or electronics in the unit
- manual control of the parameters operating pressure, total volume flow and oil dosage for individual tool-dependent lubrication with seven operating modes
- external control of the seven operating modes via three solenoid valves, on/off switching of lubrication via a solenoid valve
- suitable for all tool sizes
- in combination with our tank extension: automatic refilling (of several MQL units) during operation with filtered lubricant from central reservoir
