9.6 EXTERNAL TOOL COOLING<br />
For the external tool cooling use water with the following specifications:<br />
� Index of aggressiveness (I.A) = 11-12<br />
� Electrical conductivity: not more than 600 microS/cm<br />
� Turbidity not above 20 mg/l<br />
� Chlorides not above 300 mg/l<br />

Only an accurate analysis will tell if the water used for the machining process has the<br />
required physical characteristics.<br />
Do not use products containing sodium chloride (NaCl), which cause corrosion<br />
(rust).<br />
When using the <strong>HSD</strong> “Water flange” optional part, do not use de-scaling products<br />
in the external tool cooling circuit. De-scaling products will damage the watertightness<br />
of the “Water flange” unit.<br />
Never direct liquid or air jets to<br />
the pressurized labyrinth seal,<br />
because infiltrations damage the<br />
internal parts of the spindle.<br />
Do not direct liquid or air jets<br />
into the electrospindle when the<br />
tool-holder is not clamped in, as<br />
they could dirt the coupling<br />
surface of the taper fit or they<br />
could get dirt into the<br />
electrospindle.<br />
