The centrifugal torque of the base jaws M
cGB
can be found in the data of the lathe chuck.
The centrifugal torque of the top jaws M
cAB
is calculated.
The lathe chuck K11-200 has no base jaws and no top jaws.
Example:

The centre of gravity radius r
s
of the jaw = 0.0632 m (jaw flush with the outer diameter of
the chuck)

Weight of a jaw = 0.622kg

Centrifugal moment for one jaw

The lathe chuck has 3 jaws.

Calculation of the total centrifugal force at a rotational speed of 3000 rpm
The total possible clamping force of the chuck at a standstill is ∑
s
31 kN at a tightening torque
of 250Nm with the lathe chuck key.
An effective clamping forceF
sp
of 19.4 kN remains at the chuck.

"Basic safety instructions“ on page 86
WARNING!
The greater distance above the chuck surface that clamping occurs, the lower the
clamping force will be.
7.8 Notes on instruction of operating personnel
We recommend that the business operating our manual chucks makes the operating instruc-
tions in particular the section "Safety" available to all persons being in charge of operation,
maintenance and repair, with the intention ofacquiring specialised knowledge. We further rec-
ommend that the business operator issues internal "operating instructions" which take into
account the known qualifications of the operating personnel.
The business operator must guarantee that suitable measures in organisation and instruction
are taken to ensure that the appropriate safety rules and regulations are complied with by the
persons entrusted with operation, maintenance and repair of the manual chuck.
7.9 Scope of delivery
Note: Soft, non-stepped jaws are only available as an option.

1 manual clamping chuck (complete) with camlock bolt for direct fixing of the chuck on a
lathe as per DIN ISO 702-2 , size depending on the spindle size.

1 set of internal clamping jaws, centric clamping
