Safety instructions
Item no. 10405047-05, Revision 03 9 ( 48 )
4 Safety instructions
The high frequency spindle is a state of the art product and is safe to operate.
However, the HF spindle may pose a risk in the following cases:
qIf it is installed by untrained personnel.
qIf it is used incorrectly.
qIf it is not used in accordance with its intended use.
The high frequency spindle may only be installed, commissioned, and main-
tained by specialist personnel.
Definition: Specialist personnel are persons who are familiar with the assem-
bly, installation, commissioning, and operation of the product and have the
relevant qualifications for their area of activity. The operator must closely con-
trol the responsibility, training, and monitoring of these personnel.
DANGER: Due to explosion.
HF spindles are not approved for use in areas at risk of explosion. Use in such
areas may result in explosions.
uDo not use the HF spindle in potentially explosive atmospheres.
DANGER: Due to flying parts.
The HF spindle operates at high speeds and may therefore be flung away by
these.
uOperate the HF spindle only if it is installed in the machine or system in a
fixed manner.
Note: Adhere to the limit values.
uObserve the limit values specified in the technical data.
Note: Take account of the machine.
uObserve the manual of the machine in which the HF spindle is installed.
uObserve all safety instructions specified by the machine manufacturer.
uEnsure that the machine does not cause any hazards (e.g. uncontrolled
movements). Do not install the HF spindle in the machine until this has
been done.
Note. Do not damage the HF spindle.
uAny damage reduces the accuracy of the HF spindle.
uAny damage restricts the functionality of the HF spindle.
uAny damage shortens the service life of the HF spindle.

Safety instructions
Item no. 10405047-05, Revision 0310 ( 48 )
4.1 Safe working
Observe all safety instructions set out in the manual, the applicable national
accident prevention regulations, and the valid company work, operation, and
safety guidelines.
DANGER: Due to flying parts.
Tools that are not clamped correctly will be flung away by the centrifugal
forces that occur during machining.
uUse the full clamping depth of the clamping system.
uClamp the tool securely.
DANGER: Due to flying parts.
If the wrong rotational direction is used, the clamping system releases and
the tool is flung away.
uIt is essential to adhere to the rotational direction of the HF spindle.
WARNING: Risk of injury due to flying parts.
The HF spindle operates at high speeds which may cause chips to fly out
with great force.
uNever remove the protective devices of the machine or system.
uAlways wear protective goggles during work.
Exampleofdesign: Inserting the
shank
Note: Ensure functionality.
uNever operate the HF spindle without a clamped tool shank.
If no tool shank is clamped:
qThe clamping system is damaged by the centrifugal forces.
qThe clamping system is shifted.
qThe balance of the HF spindle is affected.
qThe bearing is damaged.
ÜTake the relevant measures to protect against splashes and spray accord-
ing to the type of machining, the type of material being machined, and the
type of tool selected.
ÄObserve the manual of the machine in which the HF spindle is installed.
ÜObtain the maximum circumferential speeds of the tools used from the
tool supplier.
Single-point tools are not suitable for high speed cutting.
If they are required for production reasons:
ÜOnly use a balanced tool.
ÄDIN ISO 1940
ÄBalance grade 2,5

Safety instructions
Item no. 10405047-05, Revision 03 11 ( 48 )
The tool cutting diameter (X) must not be greater than the maximum
clamping range (Y).
ÜAlways clamp the tool so that it is as short as possible.
ÜKeep the dimension (Z) small.
Ä(Y) See section: Technical Specifications [}14].
4.2 Shutdown of HF spindle
The procedure for shutting down the high frequency spindle for installation
and maintenance work is as follows:
ÜCompletely disconnect the power supply.
ÜCompletely disconnect the media supply (air and liquid).
ÜMake sure that the shaft of the HF spindle has come to an absolute stand-
still.
If the HF spindle is being shut down to be cleaned:
ÜReconnect only the sealing air and the taper cleaning air.
Tip: Forward the data to the controller.
uUse the option on the frequency converter of detecting the shutdown
signal from the shaft and forwarding this to the machine controller for
evaluation.
4.3 Installation and maintenance
ÜCarry out installation, cleaning, and maintenance work only after shutting
down the HF spindle and after the shaft has come to a standstill.
ÜInstall all safety and protective devices of the machine immediately after
completing work.
4.4 Modification and repair
Modifications or alterations to the HF spindle are only permitted after prior
consultation with Alfred Jäger GmbH.
Only the service partners listed in the “Service and repair [} 43]” section are
authorized to open and repair the HF spindle.
Only approved accessories have been tested for operational safety and func-
tionality.
4.5 Improper operation
The high frequency spindle is only safe to operate for its designated use.
ÜObserve the safety instructions in all sections of the manual to prevent
hazards to persons, the environment, the machine, or the HF spindle itself.
Failure to observe the safety instructions may invalidate any warranty claims
and compensation claims for damages.

Technical description

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.
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.
5.5 Taper cleaning
For guidelines on air quality,
see "Air purity classes (ISO
8573-1) [}30]" section.
Taper cleaning prevents chips and liquids from entering the shaft during a
tool change and causing contamination and damage to the inner taper and
the clamping system.
5.6 Pneumatic tool change
For guidelines on air quality,
see "Air purity classes (ISO
8573-1) [}30]" section.
The tool change or tool taper change is performed pneumatically.
During this, a mechanism is operated inside the HF spindle which clamps, re-
leases, or ejects the tool taper or collet.
