INTRODUCTION
This Operation and Maintenance Manual refers to the MaXtreme product for dry machining processes.
You can obtain the latest version by requesting it from the Technical Sales Department, or by consulting our website
http://www.DropsA.com.
This operation and maintenance manual contains important information for the health and safety protection of the
personnel who intends to use this equipment. This manual must be read carefully and kept so that it is always
available to the operators who want to consult it.
1. GENERAL DESCRIPTION
MaXtreme is designed for near-dry machining, a technology recently designed to replace traditional cooling systems
and immersion in pure or emulsified oil in machining environments for chip removal, where a controlled flow of
compressed air transports minimal amounts of cutting oil in "aerosol" format to the cutting surface. This technology
ensures lubrication of the cutting surface and enables high-performance machining while offering longer tool life and
reduced cycle times. Removing coolant from the process also provides important environmental benefits and reduces
the high cost of the waste product.
The aerosol is transported to the cutting surface from the outside (via nozzles positioned around the tool) or from the
inside, also known as "through the tool".
Internal lubrication is the most difficult to achieve due to the coalescence of oil particles inside the tool. MaXtreme
solves this by generating ultra-thin particles that can pass through the rotating tool without hindrance caused by
centrifugal force.
MaXtreme combines years of research and development in aerodynamic and fluid-dynamic effects to produce oil
particles in an ultra-fine aerosol (diameter below the micron) that allow high-performance machining.
The double vortex solution is a revolutionary system that allows minimal lubrication and superior internal or external
near-dry lubrication.
In fact, for some applications, the second nozzle optimised for higher pressures is designed to increase the aerosol
flow directly on tools with minimum passage sections, thus offering better chip outflow and constant tool cooling.
This option can operate in a hybrid configuration with the primary nozzle delivering constant and rich aerosol even at
low flow rates, reducing the 'dead zone' at extremely low flow rates.
In addition to the Machinery Directive 2006/42/EC and, due to the increase in pressure performance up to 20 bar,
MaXtreme is certified according to PED Directive 2014/68/EU, according to which the circuit identifies the following
characteristics:
- PED RISK CATEGORY = I
- PED module: Module A
- Maximum allowable pressure: 22 Barg
- Test pressure: 36 Barg
- Permissible temperature: min 0 °C –max +60 °C
- Fluid group: Group 2
1.2 SELF-ADAPTING AND HYBRID FEATURE
The self-adaptive and hybrid functions mean that no adjustments between tool changes or complex programming
configurations are necessary. The system is mounted and adapts automatically.
How it works:
the aerosol is produced using a new vortex generator that has an improved operational envelope.
A special conical exhaust nozzle design combined with a controlled surface finish fragments the oil particles by
decelerating them at a controlled speed to create an aerosol with particles smaller than a micron. When the flow
rates become very high (typically for very large utensils), an air pressure increase valve opens to integrate the airflow
for the removal of chips and heat and therefore the density is reduced of the aerosol not required for this type of
processing operation.

2. STRUCTURE AND OPERATION
2.1 LP/HP CIRCUIT OPERATION
The system consists of a pressurised lubricant reservoir with air. The lubricant contained in the tank (1) is sent through
a pipeline inside the tank itself, to the generator nozzle (3) located inside the generator head, as a result of the
pressure from the air, regulated by the valve (2).
The oil previously regulated by the valve (4) meets the airflow placed in rotation at high speed, thus splitting into
micro-particles that form the aerosol mist conveying with the opening of the electro-pneumatic valve (14), towards
the use in the CNC chamber.
By simply turning the valve (4), the quantity of oil introduced into the circuit is defined in % according to the position
of the ball on the flowmeter (11), and the fog density is varied accordingly. (only for LP mode).
Even if totally closed, the valve (4) allows a minimum oil passage that can guarantee minimum lubrication.
The flowmeter has reading integrated for both HP / LP operating modes.
The left scale reading indicates oil supply on LP circuit, while right scale indicates oil supply on HP circuit.
In case of high airflow rates, the valve (5) feeds additional air into the tank in order to keep the pressure in the tank
constant. (Ref sheet 1 –Page 6)
When using drills with very small lubrication diameters, there is an increase in pressure in the reservoir. This condition
causes the pneumatic valve (10) to open the high-pressure duct, thus activating the multiplier (8) (if present) or
external accessory connected to the port (7).
In this situation, the pressure inside the tank will tend to increase, thus closing the check valve (9). Increased pressure
will facilitate the release of machining waste material, ensuring continuous tool cooling/lubrication. (Ref sheet 2 -
Page 6)
There is no oil regulation on the HP circuit.
The oil can be filled from the port (16) or the valve (15), which also acts as an oil drain.
The max/min oil level in the tank is directly observable from the pipe (12) located on the tank.
Note: The oil level must not exceed the reference on the tank.
When topping up, make sure to exclude the mains air by acting on the valve (18), discharge the residual pressure
contained in the tank by acting on the quick-release valve (22).
It is also possible to connect a minimum level alarm (13) directly to the connector under the equipment in order to
prevent machining without lubricant when the system is unattended.
(Ref sheet 1 –Page 6)
Note: A single nozzle version is available in which the HP circuit is deactivated.
2.2 HP CIRCUIT DRIVE WITH REMOTE CONTROL
It is possible to mount an ON/OFF solenoid valve (21) externally controlled by the CNC that controls the intervention
of external accessories.
In this case, it is preferable to deactivate the pneumatic valve (10) by completely unscrewing the adjustment screw on
the valve itself. (Ref sheet 3 –Page 6)
In case of maintenance, it is possible to eliminate the residual pressure on the multiplier circuit by opening the valve
(23) and energising the ON/OFF solenoid valve (21) if present.
ADVANTAGES:
Reduction of the cycle time: from 25% to
80%.
Reduction of the quantity of lubricant
required
Longer utensil life
Improved finishing of the pieces
Application:
Machine tools;
Sheet metal cutting and bending machines;
Steel mills.

7. UNPACKING AND INSTALLATION OF THE MACHINE
7.1 UNPACKING
Once you have identified the suitable place for installation, open the packaging and remove the equipment. Check the
unit for damage during transport and storage. The packing material does not require special disposal precautions as it
is in no way dangerous or pollutant. For disposal, refer to local regulations.
7.2 INSTALLATION
The equipment can be installed in two ways:
a) Attach the equipment to the structure of the machine tool. Take care not to install the equipment in an
environment that is particularly prone to strong vibration or oscillation.
b) Install the equipment in the vicinity of the machine tool, ensuring that it is a suitable environment for this
type of equipment.
Strictly follow the following rules:
In order to avoid malfunctions, always position the equipment vertically.
NEVER turn the equipment upside down.
For filling and control of the system, place the equipment in an easily accessible environment.
NOTICE
Place the equipment on the machine
vertically and in an easily accessible location.
NEVER flip the equipment
The operator is responsible for any damage caused to the MaXtreme equipment by improper installation.
7.2.2 COMPRESSED AIR CONNECTION
WARNING
The compressed air connection must be made by
competent and qualified personnel.
For safety reasons, the compressed air pressure at the
mains air connection must never exceed 6 bar.

7.2.3 TANK FILLING
7.2.3.1 FIRST FILLING
During the first filling, it must be ensured that there is
no residual pressure inside the tank. (Ref. par.9.1).
The oil must be poured into the tank through the
special inlet (OIL RECHARGE).
The "maximum" sign (B) on the filling indicator must
under no circumstances be exceeded.
7.2.3.2 SUBSEQUENT FILLINGS
When the oil reaches the "minimum" level (A),
MaXtreme must be refilled. If the unit is in operation,
switch it off and eliminate the residual pressure
(Ref.par.9.1). Then proceed as described in 7.2.3.1
FIRST FILLING UP.
If connected in analogue mode with the minimum
level alarm, the numerical control would block the
system. In that case eliminate the residual pressure,
(Ref.par.9.1), and proceed as described in paragraph
7.2.3.1 FIRST FILLING UP
WARNING
During the filling operations, always
disconnect the system from the
compressed air by acting on the manual
sliding valve and on the multiplier supply
pressure reducer by turning it fully
counterclockwise.
When filling the tank, never exceed the
"maximum"(B) level.
NOTICE
Use the same oil in case of subsequent
fillings, otherwise make sure to remove all
traces of the lubricant previously used via
the oil drain cock.
Only then fill the tank with the new oil and
operate the equipment.
DropsA declines all responsibility for the
incorrect operation of the equipment.

7.3 PIPES AND NOZZLES
The recommended pipes have an external diameter of 12 mm for the whole part of the system that can be covered
with this diameter.
The length of the aerosol pipeline should be kept as short as possible. The longer the aerosol pipeline length, the
greater the pressure and aerosol losses.
The aerosol lines should be laid as linearly as possible, especially avoiding "narrow bows", otherwise there is a danger
of lubricant precipitation. If deflection connections cannot be avoided, they must have a radius of at least 200 mm.
The aerosol pipeline should have a continuous slope in the direction of the machine. Downward curves should be
avoided as much as possible since lubricant could accumulate at these points if the machine is stopped.
The feeding of aerosols into spindles or rotating tools should be carried out as far as possible in the axial direction. In
the case of radial adduction, it can happen, especially at high spindle speeds, that the lubricant is "centrifuged out",
thus causing a separation of the aerosol.
This is particularly the case when used with small tools with high rotational speed.
WARNING
The equipment must operate according to the
parameters indicated in the technical
characteristics.
8. OPERATING INSTRUCTIONS
The same general procedures and precautions typical of the installation of traditional lubrication and cooling systems
must be observed.
8.1 MaXtreme SETTINGS
Refer to the figure in paragraph 6
Air quantity: by air pressure regulator with pressure gauge.
Oil quantity: through the flow control valve.
8.2 START-UP - BASIC PRINCIPLES
Refer to the figure in the paragraph. 6
a) Close the air pressure regulator valve completely by turning the ring nut counterclockwise.
b) Connect the compressed air hose via the appropriate mains air connection.
c) Mount the tool in the machine.
d) Open the following valves:
Manual on/off slide valve for compressed air by moving it horizontally to (ON).
Turn the ring nut of the air pressure regulator until you get 6 bar reading on the pressure gauge.
f) Open operating valve.
g)
NOTICE
During operation in HP mode, the percentage of oil indicated on
the flowmeter may be at a maximum of 20%.
LP flow rate in percentage of oil indicated on the flowmeter may
be at a maximum of 100%.
The oil flow rate of the HP nozzle is not adjustable.

16
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.
