Operation
Clamping Ø 3 – 5 mm:
• Select the parameters for Ø 3 – 5.
• Press the
key.
The coil travels to the desired position.
• Press the key
. The aperture opens.
• Unlock the ferrite ring (30) by turning it clockwise.
• Remove the ferrite ring (30).
• Insert the insert ring (55).
• Lock the insert ring (55) by rotating it counterclockwise.
• Insert the ferrite ring (30) again once the shrink fit
operation has been completed.
5.3.4.3 Coil with stop disks
The purpose of the stop disk (49) is to correctly position the
coil under the shrink fit chuck (52). In addition, the stop disk
(49) protects the shank of the tool against heating up due
to stray magnetic fields.
Caution: If the stop disk (49) is missing or set incor-
rectly, stray fields could be emitted from the coil area.
On a long-term basis these stray fields could affect
the health of the operator. For that reason the coil
should never be used without a stop disk (49).
The stop disk (49) is inserted by hand. The stop disk (49)
is attached by a bayonet fastening.
Caution: After long use or after resting on a hot
chuck for a long time, the stop disks can become hot.
There is a danger of being burnt. When changing the
disks, always wear protective gloves. This applies in
particular to the disks for the inductor for Ø 40 – 50
mm (20 kW), since they are not jacketed.
• Select a stop disk (49) to match the tool.
• Insert the stop disk (49) into the coil from above.
• Turn the stop disk (49) clockwise until it audibly clicks
into place. A spring element clicks into place in a notch
in the stop disk (49).
In the case of tools with an increased cutting diameter
(e.g., T-slot milling cutters), under certain circumstances
the cutting diameter is greater than the hole in the stop
disk. For such a situation there are split stop disks. These
washers are in two halves. After the shrink fitting operation
the washer halves are removed first before the coil is lifted
out over the tool. In an unshrinking operation the coil is
first lowered over the tool without a washer disk. The disk
