Attaching and removing the clamping device
Check the machine spindle head or the finished intermediate flange or basic take-up
on the machine for concentricity and axial run-out (0.005 mm permitted according to
DIN 6386 and ISO 3089).
The flange/basic take-up must be designed such that the mandrel has contact with its
square face. The square face on the flange/basic take-up or spindle must be
absolutely level.
Attaching the clamping device
 Move the draw tube into the foremost position.
 Push the connection piece / bayonet piece in the rear position in the clamping
device.
 Turn the clamping device up to the stop on the draw tube.
 Turn the clamping device back until the fastening bore is aligned with the
fastening thread.
 In the case of a bayonet connection, stick the bayonet on the basic take-up
and turn.
 Press the clamping device against the spindle take-up, move the draw tube /
bayonet piece to the rear position using minimal force.
 Lightly tighten the mandrel fastening screws.
 Correct axial run-out and concentricity. Afterwards, tightly mount the clamping
device on the spindle (firmly tighten mandrel fastening screws).
 Check function and magnitude of the actuation force.
 Check clamping device for concentricity and axial run-out using the control
ring.
 Disassembly is done in the opposite order.
