Tiny amounts of a high-performance lubricant are pulverised where they are needed by an accelerated air flow. A liquid micro-coating is produced between the tool and workpiece.
Pneumatically activated piston pumps deliver tiny, exactly reproducible amounts of the high-performance lubricants developed by UNILUBE into a capillary tube. Spray air is delivered separately in a ring line at an operating pressure from 5 to 8 bar. Via these coaxial lines, the lubricant and air get to the areas to be lubricated as close as possible, reaching them separately. For example, that may be the cutting edges of cutting tools or also the surfaces of profiles being metal formed. A special mixing nozzle pulverises and delivers the micro-dosed lubricant particles in an accelerated air flow to apply an extremely fine lubricating film on tools and components being machined.
For a particularly fine-tuned minimal quantity lubrication – for example in case of micro-machining in the precision engineering of watches or in the medical technology sector – the tried-and-tested UNILUBE minimal lubrication systems can generate a permanent micro-lubricating film even with an extremely low lubricant dose of 0.2 ml an hour. The basic settings for the delivery of air and lubricant are manually adjusted to the actual machining process. By means of an external control signal or indexed control, the lubricant delivery rate can be adjusted dynamically to the machining process.
Why this works better than a flood cooling system with emulsions or oils is explained by us in our technical article “Physical principle?”.
