8.3 INTERNAL LUBRICATION
MaXtreme
is used for internal lubrication work: the aerosol is brought inside the tool via the spindle.
In such a situation, it is suggested to follow the following instructions:
The spindle must be suitable for the type of application in question (dry machining).
Some spindles have a non-return valve. This could be a problem due to the relatively low working pressure of
the system. A valve modification may be required. Ask
DropsA
for advice.
Make sure that the hose used to transport the oil does not have any alterations such as cross cuts, cracks or
cracks. In this case, the lubricant would be deposited in the cracks and would not reach the correct amount at
the cutting point.
Be advised when choosing the ideal tool for minimal lubrication.
Ensure that there is no excessive bending or shrinkage (diameter reduction) of the piping in the lubrication
line. This would result in a deposit of lubricant in these areas preventing the aerosol from reaching the
machining centre.
Make sure that aerosol mist comes out of the tool.
The workpiece must be positioned at a maximum distance of 40 mm (1.57 in.) from the outlet of the
minimum lubrication channel to ensure the formation of a thin film of lubricant.
The amount of aerosol mixture must be appropriate for the type of processing. If necessary, change the flow
quantity through the oil flow control valve. (
Ref. par. 6
)
NOTICE
MaXtreme
is capable of effective lubrication through very small
tool channels (capillaries); in this case, it may be necessary to
configure the system for aerosol pressure up to 20 Bar.
For a greater system efficiency, we recommend the use of the
same tools or with a similar internal lubrication passage, if used at
the same time.
