Checking the clamping force
The minimum number of rotations are indicated on the HTC clamping chuck (see section 4.2) and provide a simple and reli-
able check of the clamping force. This ensures that the minimum transferable torque is achieved at each clamping opera-
tion. The minimum number of rotations are the number of rotations of the clamping screw that have to be achieved from
the gripping point of the shank up to the stop of the clamping screw. The gripping point is the position of the clamping
screw in which the tool shank can no longer be turned with two fingers or pulled out of the location bore.

INFORMATION
Actuation of the HTC clamping chuck is possible from both sides. The HTC clamping chuck can be adjusted either
axially or radially, depending on the design.
WARNING
Shrinking or heating the HTC clamping chuck can lead to injuries and damage to machines and accessories!
Shrinking or heating can cause the HTC clamping chuck to become deformed or to burst explosively. Hot oil,
oil vapours and metal slivers can then fly around uncontrolled and cause serious injuries to the operator and
cause damage to machines and accessories.
Do not shrink the HTC clamping chuck or heat it above the specified operating temperature.
