5.2 Electrical connection
The HF spindle may only be operated with a frequency converter (FC).
ÜCheck whether the current, voltage, and frequency data of the HF spindle
match the raw data for the frequency converter.
ÜUse a motor supply line that is as short as possible.
ÜAdjust the speed of the HF spindle using the FC.
ÜRefer to the frequency converter manual for further information.
The FC detects the following operating states of the HF spindle, depending on
the version:
qHF spindle rotating.
qHF spindle too hot.
qHF spindle at a standstill, etc.
The FC forwards the operating states of the HF spindle to the machine con-
troller.
Note: Connect the SpeedTEC quick locking connector.
uFor the combination SpeedTEC connector plug/SpeedTEC cable plug:
uRemove the O ring on the SpeedTEC connector plug.
5.3 Cooling
Liquid cooling keeps the HF spindle at a constant temperature during opera-
tion.
Note: Extension of the service life through heat dissipation.
Heat is produced during operation of the HF spindle. The temperature of the
HF spindle should not exceed + 45° C as this shortens the service life of the
bearing.
uCheck the temperature of the HF spindle on the housing.
5.4 Sealing air
For guidelines on air quality,
see "Air purity classes (ISO
8573-1) [}30]" section.
The sealing air prevents foreign bodies such as chips and liquids (e.g. emul-
sions) from entering the HF spindle.
ÜCheck that air escapes at the front between the housing and the rotating
parts of the HF spindle.

Technical description
Item no. 10206007, Revision 00 13 ( 44 )
5.5 Internal coolant supply
The internal coolant supply cools the tool and the HF spindle.
The tool coolant is routed internally through the HF spindle and tool, and
emerges at the interface of the clamped tool. The coolant lubricates the tool
at the same time.
Note: Unsuitable tool.
Tools without an internal hole are not suitable for internal coolant supply.
uIt is essential to switch off the internal coolant supply if tools without an
internal hole are being used for production reasons.
If this is not done, the HF spindle will be damaged or destroyed.
ÜOnly use tools and tool holders that are suitable for internal coolant sup-
ply.
ÜMake sure that the cooling lubricant used conforms to the current specifi-
cations in legislation and from the trade associations.
5.5.1 Cooling lubricant
ÜDo not use pure or distilled water.
ÄSuch water causes immediate corrosion on bare parts, which is often un-
noticeable at first, but later leads to serious corrosion damage.
ÜOnly use cooling lubricants that comply with the following guidelines:
Corrosion protection in accordance with DIN 51360 Part 2:
No corrosion after 2 hours.
Compatibility with elastomers:
No change to Shore hardness values or elongation
Compatibility with non-ferrous metals:
No damage to copper, brass, or aluminum parts
Adhesive residue behavior after slow evaporation at 50°C:
Not adhesive.
No “adhesive tape effect”
Easily resoluble or re-emulsifiable.

Technical description
Item no. 10206007, Revision 0014 ( 44 )
5.5.2 Filtering the cooling lubricant
Unfiltered flow media with a particle size in excess of 50 µm lead to increased
wear.
ÜUse a filter upstream of the internal coolant supply that filters out particles
that are bigger than 50 μm from the medium.
The greater the number of particles in the flow medium, the greater the wear
on the internal coolant supply.
5.5.3 Avoiding pressure peaks
Pressure peaks mainly occur when an incompressible medium (e.g. cooling lu-
bricant) collides at high speed with a closed or almost closed hole. This impact
may cause the pressure to increase to many times the permitted pressure.
ÜSelect the duty cycle of the valve so that the peaks in pressure that occur
not exceed the normally permitted operating pressure.
Closing valves may also cause excessive pressure (fluid hammer).
Excessive pressures may also occur when pressure is additionally applied to an
incompressible medium (e.g. cooling lubricant) in a closed space due to a
stroke motion.
ÜRemedy: ventilation.
5.6 Leakage
Note: Damage to the HF spindle due to leakage.
Cooling lubricant may enter the HF spindle through the bearing of the inter-
nal coolant supply and destroy it:
qIf the internal coolant supply is operated in the lower pressure range.
qIf the pressure of the cooling medium builds up slowly.
uUse leakage monitoring to protect the HF spindle from damage.
