It is possible to adjust the speed of the Air Turbine Spindle by controlling the air pressure with a
regulator. Please consult the below table. (The values indicated in the below table are reference
values. Depending on the model, the speed may differ by 5%.)
Please refer to the table indicating the air pressure and the spindle speed on the body of the Air
Turbine Spindle.

Caution
Since the air purge does not work when the air is not supplied to the Air Turbine Spindle,
under this situation, coolants, etc. may be able to invade the internal parts. For this reason,
start supplying the air to the turbine before starting the application of coolants and oil mists. In
case of stopping the application of the coolant, please execute the operation continuing to
supply the air to the turbine.
The Air Turbine Spindle, by using air purge for moving the turbine, is built to prevent coolants and oil
mists from invading the internal parts of the holder. However, if the coolant is applied directly on the
spindle body, it may invade its internal parts.
Pay attention to not apply the coolant directly on the body of the Air Turbine Spindle.
Coolants and foreign bodies, by invading the internal parts of the unit, will reduce the lifespan of the
bearings.

Always respect the recommended torque when clamping the pull-stud bolts. In particular for
BBT30, exceeding the recommended values will easily bulge the taper, due to the thickness of
the small part of the taper. Since, when the Air Turbine Spindle is used, the spindle of the
machine does not rotate, the clamping torque of the pull-stud bolts is a little lower than normal.
Follow the below procedures to install the pull-stud bolts.
Check if the machine and the pull-stud bolts are compatible.
Clean the installation holes of the taper and remove the grease of the pull-stud bolts.
Apply an anti-loosening solution. (Refer to the operation manual of the anti-loosening manufacturer
for details regarding the application method.)
Always use the torque wrench (available on the market) and clamp following the below
recommended torque.

The locating block is necessary for the air supply. Since the measures and the shape of the locating
block depend on the model of the machining center, control, by checking the operation manual,
drawing and materials of the machine that the block is actually suitable for the machine’s spindle.
Caution
A tap hole for plumbing laterally the air is always necessary for the locating block.
When installing the air to the locating block, use an air filter. An air rich with moisture and
foreign particles may damage the bearings.
In case of using the ATC, before installing the Air Turbine Spindle release one time the air
for clean the ditches and the internal parts of the block.
To the customers that currently use our High Jet Holder, High Spindle, etc and
have already installed the locating block in the machines
Even if the locating block for the Air Turbine Spindle and the locating block for the holder of the
High Jet Holder, High Spindle, etc have the same shape, please avoid a shared use. In case of
the Air Turbine Spindle, the air supplied from the locating pin has to be pure. If a locating block
that has used in the past coolants, is used for the Air Turbine Spindle, the coolant invading the
Air Turbine Spindle, may reduce its efficiency and life due rust, etc.

Caution
Be sure to do the checks when performing the manual installation.
If there are errors in the settings, the Air Turbine Spindle may be damaged during the ATC.
INSTALLATION (Side through type)
After the orientation (M19) of the machining center’s spindle, fix the drive key’s position and install
manually the Air Turbine Spindle on the machine. At this time check that the drive key and the
locating pin enter without problems.
Execute the ATC after have checked the procedures from 1-1 (P9) to 1-5 (P11) and the below attention notes.
Caution
Please reduce the ATC speed.The impact with the ATC may damage the tool in case of using
tools with small diameter.
Do not rotate the machine’s spindle at high speed or for a long time when the Air Turbine
Spindle is installed in the machine.
(When the unit is fixed on the case with the locating pin, since it is built to let rotate only the
internal part of the holder even if the machine’s spindle is rotated, high speed and long time
rotations will lead to damages due being stuck, etc.)
It is not a problem to rotate the machine’s spindle for the orientation at the moment of the ATC.
Pay attention that a clutch movement of the locating pin higher
than the prescribed amount (6mm) will exert an eccentric load
on the case and add an anomalous load to the bearings leading
to heat and a reduction of the lifespan. Pay also attention that
a movement of the locating pin inferior to the prescribed
amount will not release the lock mechanism. If the spindle is
rotated in this situation the Air Turbine Spindle may be
damaged. The correct position has a gap of 2mm and 1mm on
each side of the clutch. (See the figure on the right)
Check that the setting measures of the “Inspection sheet” included with the Air Turbine Spindle
match the values of the machine’s spindle nose.

Do not use air that contains large quantities of drain (moisture, oil, dust).
Install the device vertically in order to have the drain valves pointing downward
Arrange enough space under the “Air filter regulator” for changing the elements and for draining.
Before doing the plumbing, clean the tubes removing chips, coolants and foreign bodies.
Prevent tensional and bending moments on the “Air filter regulator” other than its own weight.
(Pay attention in particular when using pipes like steel pipes, etc., that do not have flexibility.)
Cautions regarding the maintenance
Since the Air Turbine Spindle uses compressed air as driving source, if an air rich with moisture and
foreign bodies is used, the bearings may rust or get stuck reducing the tool life. In order to use pure
air, the following device is recommended. Even when using the center through type, always use a
filter (mesh: 0.01mm or above) to supply pure air from the machine’s spindle.

Caution
Do not apply the anti-rust oil on the body (muffler case, locating pin, etc.) of the unit.
The oil invading the unit may lower the life of the bearings.
Protect the air inlet so that foreign bodies, dust, etc. do not penetrate.
Apply anti-rust oil on the internal and external diameters of the chuck and on the taper shank.
Check that the pull-stud bolts, the internal and external diameters of the chuck and the taper
shank are not affected by rust.
Remove completely the anti-rust oil.
Before connecting the air tube to the unit, release the air to check that moisture, etc. is not
present inside the tube.
Perform a warming-up operation.
It is not necessary to oil the internal parts of the unit. We will grease the unit when doing the
overhaul.
Never disassemble or modify the unit. Otherwise, it will be considered outside the normal
overhaul or repairs.
It is recommended to perform the overhaul after 1 year from the first operation or when the
operation time exceeds 2000 hours. The overhaul is also recommended if the unit is not used
for a long period of time (1 year or more). Return the unit through our distributors for the
overhaul. The overhaul is charged.
Stop immediately the operation and contact us in case of strange noises and nasty smells
coming from the Air Turbine Spindle or in case of strong vibrations.
In addition do not continue to operate with strong vibrations (chattering process).
