It is a safe and economical greasing system, an innovative technology for lubricating high speed spindles with air / oil. The main application of this system is the lubrication and cooling of the internal bearings of the spindles. Air/oil lubrication is based on the principle that a drop of liquid is split by airflow, dispersed in streaks and transported in the direction of the airflow. The drops are transported along the inner wall of a narrow tube in the direction of the lubrication point. With an appropriate length of tube (minimum length 1 m) and a sufficient sequence of oil-delivery cycles, a continuous flow of lubricant arrives at the outlet where it is compressed in the nozzle and fed to the friction point in relatively “large” droplets with the help of air. The oil remains at the friction point and the air, which unlike oil mist lubrication is nearly free of oil, can escape unimpeded into the open. The air protects bearings from outside contamination and has a fresh effect on the bearings.
The pneumatic micro-pump system is equipped with an inductive sensor. This allows to verify currently, the dosage of the lubricant to the point to be greased. This verification is done on each individual discharge.
