ABSTRACT --- The most common method used to lubricate saws, milling cutters,
drills, taps, punches, mandrels and other tools used in the fabrication of aluminum
billets, castings, and extrusions, dispenses tiny amounts of liquid from a gravity
reservoir. This process uses a positive displacement injection pump that is mixed with
air at the point of application. These systems were originally introduced in the United
States in the mid 1980s and quickly became the worldwide industry standard when
combined with high performance, non-staining, biodegradable lubricants. The original
spray equipment designs, although well received, were not well designed relative to the
rough working environment associated with billet casting, extrusion, and fabrication.
Over time, this type of equipment has been incrementally improved; however, several
recent developments will revolutionize the installation, use and maintenance of these
precision lubrication systems. These developments include: enhancements to the
reservoirs; injection meters; and the liquid/air transport mechanisms, which improve
system reliability and functionality while also reducing the system repair time of the
spray equipment and the machine on which they are installed. Further, these
developments also allow for subcomponent repair, as opposed to replacing a complete
component or the entire spray system. System changes are available on new
equipment or can be retrofitted to existing spray applicators.
