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.
