2.2 Intended use
The 3-jaw power chuck with centrifugal force compensation of Type 3QLCLM is engaged through a
rotary double piston clamping cylinder. Its axial actuating force must be suitable for the power chuck.
The power chuck 3QLCLM must be used
only for its intended purpose. Intended use
is the
clamping of work pieces on lathes and other tooling machines.
The maximum gripping force and maximum speed of the chuck must not exceeded. The permissible
speed or the required gripping force must be determined for the application in accordance with the
applicable technical rules (e.g. VDI 3106). In case of doubt or accessories not provided by the
manufacturer, the threshold values must be approved by the manufacturer or redefined.
The following factors must be taken into consideration:
•
Variable friction coefficient between work piece and top jaw
•
Proportion of clamping diameter and working diameter
•
Magnitude of the cutting force on the cutting tool
•
Swing of the top jaw from the clamping point
•
Decrease of the gripping force through centrifugal force due to external clamping
Even adherence to the assembly, commissioning, operating and repair conditions prescribed by the
manufacturer are part of intended use. Any and all other usage is considered improper use. The
manufacturer cannot accept liability for damage resulting from such use.
