For many years, FORKARDT has set
the pace, worldwide, for chuck development. For example, in 1979 FORKARDT
invented the NHF chuck, the first power chuck to combine centrifugal counterbalance,
wedge hook mechanism and automatic lubrication - a chucking system which
has been adopted by many others in the business and arguably has become
the most copied power chuck ever.
Now FORKARDT has advanced power chucking technology yet again. The concept
we followed is straightforward: We took the best qualities of the NHF chuck
together with new design ideas, techniques and materials which, when combined,
meet the stringent manufacturing needs of today. The result is in many ways
an improved version of the NHF chuck, but a chuck which is sufficiently
different to deserve the new name QLC. The new QLC offers the reliability,
efficiency, precision and longevity you have come to expect from FORKARDT.
The key characteristics are summarised below. Meanwhile, rest assured that
FORKARDT continually strives to make the best even better so you get improved
value for money, productivity, reliability.
So, by now you should be convinced that the QLC is technically superior.
But is it affordable you ask. Well, you will probably be surprised to hear
that it doesn't cost a single penny more than the NHF. You can take advantage
of the most advanced technology at no extra cost. This is truly FORKARDT
at its best!
Furthermore, our customers who use NHF chucks can rest assured that FORKARDT
will continue to offer the usual service and stock of spare parts in the
future.
In summary, the QLC is stronger, more stable, with both higher accurary
and repeatability. It has centrifugal force compensation, a large bore hole,
and requires less frequent maintenance. Your downtimes are reduced, and
your quality and productivity are increased. Surely, it is not a question
of whether you can afford to buy the QLC, it's a question of whether you
can afford not to own a QLC chuck!
Don't take unnecessary risks - buy original FORKARDT!

The new FORKARDT QLC power
chuck :
 |
New base jaw profile with optimal
length of bearing for both internal and external clamping |
 |
Increased stability due to multiple
jaw guides and reduced jaw overhang |
 |
Profile ground base jaws - no loss
of lubrication due to undercuts or open fissures |
 |
Internal grease supply with improved
forced circulation |
 |
Permanently engaged wedge hook mechanism,
backlash free, for highest gripping forces and repeatability |
 |
Centrifugal force compensation for
consistently high gripping forces |
 |
Large throughbores for bar chucking |
 |
Optimum combination of materials
- all working parts are hardened and ground |
 |
Simplified mounting - connection
inside the chuck, no overhang to the rear |
 |
Axial stroke limitation inside the
chuck, stroke overtravel does not impact the system |
 |
Base jaw location availbable as standard
in European and US norms |
 |
Optional quick-change jaws |
 |
Designed and produced according to
ISO 9001. |
