<\/p>\nUnilube generally recommends using tools with internal cooling, where the high-performance lubricant reaches its point of application by means of internally supplied compressed air.<\/p>\n
This method soon comes up against its physical limits, however, when it comes to very small tools used in micro-cutting. In addition, the tool spindle used provides no room for a central supply of lubricant due to its limited dimensions. With just one lateral nozzle, although enough lubricant reaches the tool in case of high-speed micro-tools, shaded areas may arise depending on the nozzle positioning and workpiece that interrupt the application of micro-lubricant film. This can be the case especially in 5-axis machining.<\/p>\n
In order to ensure a constant film of micro-lubrication without discontinuities, with the semi-annular nozzle the jet is split from one supply by a dual nozzle unit, in other words two \u201cnozzle levels\u201d, and applied from several sides to where it is needed with pinpoint accuracy. <\/p>\n
The finely coordinated micro-nozzles guarantee an all-round constant application of micro-lubricant film onto the tool. By varying the nozzle outlet angle, extremely different tool lengths can be reliably serviced with the innovative Unilube ltotal-loss ubrication if required.<\/p>\n
Originally developed for the watchmaking industry, this proven \u201cdual nozzle principle\u201d, adapted to customer-specific structural shapes, opens up interesting and various possible applications including the tube machining sector. Moreover, the low operating costs with oil consumption of less than 1 litre per year are surely record breaking.<\/p>\n
